Lean Manufacturing in Steel Companies

Steel companies have caught up with the fever and are trying to implement lean manufacturing in their operations. Lean manufacturing of steel is a production process that seeks to eliminate waste in all steel production phases with the end purpose of satisfying the customer.

Results of a successful implementation of lean manufacturing of steel are monumental: huge reductions in production cost and inventory and cycle times, large gains in quality, and evident improvements in delivery reliability.

Traditional approaches to implement basic lean manufacturing in companies involve :

(a) a top-down rolling out of concepts

(b) installing and following goal-curves across management levels, meaning departmental goals must be in sync with each other and people are held accountable to meeting their targets

(c) doing the easy tasks first and gaining momentum from small successful results

(d) interactive education and creating at atmosphere that welcomes taking risks and

(e) initiating a pilot project before wide scale implementation.

Although very worthwhile, lean manufacturing is a very complicated process by itself. Lean manufacturing of steel even creates unique problems.

Steel parts that carry loads like automotive trains, jet engines, industrial bearings and metal-forming machinery are produced in a time-consuming multi-step process that involves a lot of grinding and polishing.

Steel parts are first molded out of metal that is relatively soft and then hardened by being subjected to high heat and quickly cooled in a liquid, or “quenched.” After this, steel parts still require precision finishing processes to produce ultra-smooth surfaces that reduce friction and wear

In steel production, equipments are often physically huge that rearrangement of these to reduce unnecessary human and machine movements may be unrealistic. Some processes in manufacturing of steel must be performed in large batches.

Because of the size of the products made, cycle time is often longer than in other manufacturing businesses. Metallurgical constraints limit the aggressive acceleration of heat-up and cool-down cycles.

Difficult equipment set-up increase production time, effort, yield loss and equipment deterioration. Protective inventories are necessary to avoid costly “out of metal” conditions during bottleneck operations and cannot be avoided.Traditional “kanban” or “signal controls are not suitable because some mills have a variety of routings and passes on the same equipment.

Also, unions and uncooperative labor relations make empowerment of employees and team building difficult to establish.

Despite these drawbacks, there have been success stories of lean manufacturing of steel.

In order to slash manufacturing costs by up to 30 percent and as to add $6 billion to the U.S. economy every year, Edison Materials Technology Center developed and refine, from 2000 to 2005, an innovative technique for making a wide array of hardened steel parts through lean manufacturing of steel.

“Hard turning”, a method to forge hot metal into nearly perfect parts and hardening and machining these after, was discovered to eliminate waste and possibly the need for polluting oils which are used in cutting and grinding. If hard turning will be applied to manufacture gears and turbine blades, this would meet EMTC’s goals.

EMTC has developed hard-turning technologies and a complete prototype system. Other members of the team are Delphi Automotive Systems, Torrington Co., Kennametal, Third Wave, Hardinge, Inc., Masco Tech, Georgia Institute of Technology, and Ohio State University.

Applying lean manufacturing of steel, Cairns Steel Fabricators also doubled its capacity and improved productivity. Established in 1979, CSF is a company focusing on steel fabrication and erection which employs around 60 personnel and handles 150 tonnes of steel per week.

QMI solutions offered a holistic approach to lean manufacturing of steel through its ProEdge Manufacturing Excellence program.

To ensure lean manufacturing of steel, CSF decided to address its internal processes first before expanding. CSF altered factory layout, house keeping and machinery setup. Efficient use of space and equipment resulted to increased productivity.

CSF positioned individual work areas in specific spots and color-coded tools to ensure they are returned to their proper places. In CSF’s case, it was important to look at the “little everyday things” in order to make the system leaner.

Getting In Shape With Lean Manufacturing Techniques

Everyone wants to have a good physique and a healthy condition. When the entire body is working efficiently, the individual said to be strong and resistant to diseases. Training the body and toning the muscles can achieve this.

This analogy works in the business organization system. All departments work like the different parts of the body. When one is efficient and the others are lagging, the entire unit is not working at the optimum level. Lean manufacturing techniques can firm up the company by reducing wastes and making the organization better

Lean manufacturing is a management philosophy that concentrates on eliminating wastes and dividing the resources of the company into departments and business projects that requires the most immediate attention. The lean manufacturing techniques gives the company the opportunity to harness the best possible mix of all the best their organization can offer.

The first step in lean manufacturing techniques is to hire a lean manufacturing techniques consultant. Just like in a gym, a person hires a trainer to teach them the proper way to exercise, tone and sculpt their bodies. In the same way, companies must hire a lean manufacturing techniques consultant to guide them on how to achieve zero waste in the workplace.

Depending on the lean manufacturing techniques consultant and services that they offer, the standard process of training involves teaching the staff, employees and managers in a classroom setting. The concepts of lean manufacturing must be clear to these people in order for them to fully appreciate the benefits of streamlining their systems.

Lean manufacturing techniques involves analyzing the problematic parts of the organization, including the production department, making an assessment of the most inexpensive yet effective solution an implementing it to the organization.

Lean manufacturing techniques programs

There are different types of lean manufacturing techniques programs available to businesses. Some of these are:

1. 5S – This is a simple and highly effective set of lean manufacturing techniques techniques that removes waste from the work environment through a better workplace organization, general cleanliness and effective visual communication.

The 5S means: Sort, Set in order, Shine, Standardize and Sustain. The 5S lean manufacturing techniques program clearly positions the methods within the framework of the principles of lean manufacturing and the improvement of values in the organization.

The core of this 5S lean manufacturing techniques program is that to achieve an easy flow of products or services in the company in small groups, cleanliness and a followed set of procedures is needed.

2. Hoshin Kanri – This type of lean manufacturing techniques makes an aligned team. It makes employees feel part of the development of the system. Because of this, the smaller units of the corporation help higher management achieve goals more effectively as new kaizens are identified and implemented, all consistent with the vision and strategy.

3. Kaizen – This type of lean manufacturing techniques is applied as a part of the system level approach to improvement. Kaizen events, also known as Kaizen Blitz, is a focused, more intense short-term projects that are made to improve the process of a certain department.

Kaizen events takes companies away from the traditional lengthy projects where valuable time and money is spent more on planning rather than making actual changes in the company.

4. Kanban – This is a type of lean manufacturing techniques focuses on the pull system of an organization. Kanban represents the visual aspect of the physical storage locations in the retail business.

Kanban and Supermarkets work hand in hand to establish and maintain the interactive relationship of the products from the customer back to the producer and to the supplier/s. Lean manufacturing techniques explain the kanban scheduling systems that makes a more efficient way of stocking the goods from the warehouse to the point of purchase.

5. Set-Up Reduction (also known as Single Minute Exchange of Die or SMED) – This is a lean manufacturing techniques system that is often ignored. When the company doesn’t have standard or set of procedures to follow on the start of any working activity, time is wasted. Lean manufacturing techniques flexes this attribute by effectively allowing employees to get used to a system and then do it frequently for more efficiency.

There are only a few of the lean manufacturing techniques program available to any business. Six Sigma training, value stream mapping, lean assessment, lean accounting and standardization of work are among others.

Get a leaner and more effective company by undergoing lean manufacturing techniques. You will have no regrets with the number of benefits this training system can do for your organization.

Sustaining the Gains from Lean Manufacturing

Lean manufacturing is becoming a popular and widely used set of techniques and approaches aimed at boosting profitability and increasing competitiveness among major companies worldwide.

Because the world economy has somehow been subjected to various crises and turmoil from political and other economic hurdles, companies around the world are currently on the receding trend.

That is why companies do acknowledge the importance of integrating within them and adopting the helpful and effective strategies and principles of lean manufacturing.

Since lean manufacturing is basically involved in obtaining the right things, putting them to their proper and right places, during the right time, at the same time in ample and sufficient quantities, companies adopting them should really be careful in implementing them.

Lean manufacturing fundamentally aims to reduce waste and make companies more competitive by helping them turn into flexible firms which are open and subject to positive developments, innovations and changes.

Hence, the real challenges faced by all firms adopting the lean manufacturing principles are those that revolve around how to sustain gains from lean manufacturing.

Gains from lean manufacturing

There are several identified benefits that can surely arise from successful and effective implementation of lean manufacturing principles.

It is apparent and logical to state that lean manufacturing can have positive, direct and immediate influence and impact on companies. Implementation of lean manufacturing measures and techniques will surely and undoubtedly bring about numerous and significant gains and benefits to companies.

Lean manufacturing is sure to get companies reduce or slash manufacturing time without sacrificing output number and quantities. Experts believe that by implementing lean manufacturing principles within operations, companies can have a 50% to 90% reduction in overall manufacturing time.

That gain from lean manufacturing can be sustained only by continuing to implement effectively the helpful and effective principles of lean manufacturing.

Space gains

Another gain sure to be brought about by effective implementation of lean manufacturing is the reduction or lessening of floor space requirements.

Because lean manufacturing also involves the effective and strategic elimination of wastes and unproductive equipment in the work place, companies are expected to maximize space, making worker freer and faster to move around the work stations.

That could be sustained by preventing to buy unnecessary equipment. Redundancies and duplication of machines’ purposes and intent should also be avoided.

Increased benefits

If lean manufacturing reduces manufacturing time and floor space requirements, it can, on the other hand, increase a number of gainful aspects.

For one, productivity of companies increase by using and adopting the lean manufacturing principles and techniques. As mentioned earlier, because disruptions and unnecessary wasteful machines are taken out of the work place, personnel are more free to move around.

The comfort given to employees make them more efficient and thus make them more produce more outputs. In turn, that could be to the advantage of the company.

That lean manufacturing gain can be sustained by maintaining the smooth and effective implementation of lean manufacturing strategies and techniques.

Other gains of lean manufacturing

Companies adopting and integrating lean manufacturing techniques in their operations are also expected to improve their overall customer and client focus, boost the leadership potentials of their key personnel and make up for a leaner structure of the business.

What benefits would it be if companies achieve these gains? Of course, the overall profitability, competency and image of the company will be significantly boosted.

That would really count amid an intense competition, hard economic environment and overall rising of operational costs among companies.

To sustain such gains, it would be really imperative for companies to really maintain their focus on their goals and priorities upon implementing lean manufacturing techniques and principles.

Companies should remember that reaping benefits from such strategies upon initial successful implementation should not be a guarantee that the gains would keep on pouring.

Strong will power and determination would really keep companies afloat and surviving. Sustaining gains would be as hard an activity as seeking profit improvements and boosting competitiveness, but it is one concept and aspect, companies should really strive to get into.

Why Deploy Six Sigma?

Why Deploy Six Sigma in your organization?

Here are some reasons why we should be using Six Sigma to make process improvements:

a) It is a structured approach – if we follow the process, people will not forget any important steps along the way before they implement the solution.

b) It helps quantify the benefits and thus make it easier to sell the improvements to senior managers in the company.

c) It uses facts & data and the rigor of statistical testing to arrive at the right root cause instead of fixing symptoms or putting band-aids.

d) There is a greater likelihood of the solution being sustainable if we follow the Six Sigma process.

e) Six Sigma focuses of solving the right problems using the project selection matrix.

f) It has proven itself in a large number of deployments. Frankly, there is no better tool out there to make process improvements – especially when the root cause or the solution is not known.

Elements of the Six Sigma Framework

Elements Of The Six Sigma Framework

Management strategies, such as TQC, TQM, and Six Sigma, are distinguished from each other by their underlying rationale and framework. As far as the corporate framework of Six Sigma is concerned, it embodies the five elements of top-level management commitment, training schemes, project team activities, measurement system and stakeholder involvement.

Stakeholders include employees, owners, suppliers and customers. At the core of the framework is a formalized improvement strategy with the following five steps: define, measure, analyse, improve and control (DMAIC) which will be explained in detail in Section 2.3. The improvement strategy is based on training schemes, project team activities and measurement system. Top-level management commitment and stakeholder involvement are all inclusive in the framework.

Without these two, the improvement strategy functions poorly. All five elements support the improvement strategy and improvement project teams. Most big companies operate in three parts: R&D, manufacturing, and non-manufacturing service. Six Sigma can be introduced into each of these three parts separately. In fact, the color of Six Sigma could be different for each part. Six Sigma in the R&D part is often called “Design for Six Sigma (DFSS),” “Manufacturing Six Sigma” in manufacturing, and “Transactional Six Sigma (TSS)” in the non-manufacturing service sector. All five elements are necessary for each of the three different Six Sigma functions. However, the improvement methodology, DMAIC, could be modified in DFSS and TSS. These points will be explained in detail in Sections 2.6 and 2.7.2.2 Top-level Management Commitment and Stakeholder Involvement

(1) Top-level management commitment

Launching Six Sigma in a company is a strategic management decision that needs to be initiated by top-level management. All the elements of the framework, as well as the formalized improvement strategy, need top-level management commitment for successful execution. Especially, without a strong commitment on the part of top-level management, the training program and project team activities are seldom successful. Although not directly active in the day-to-day improvement projects, the role of top-level management as leaders, project sponsors and advocates is crucial. Pragmatic management is required, not just lip service, as the top-level management commits itself and the company to drive the initiative for several years and into every corner of the company.

There are numerous pragmatic ways for the CEO (chief executive officer) to manifest his commitment. First, in setting the vision and long-term or short-term goal for Six Sigma, the CEO should play a direct role. Second, the CEO should allocate appropriate resources in order to implement such Six Sigma programs as training schemes, project team activities and measurement system. Third, the CEO should regularly check the progress of the Six Sigma program to determine whether there are any problems which might hinder its success. He should listen to Six Sigma reports and make comments on the progress of Six Sigma. Fourth, he should hold a Six Sigma presentation seminar regularly, say twice a year, in which the results of the project team are presented and good results rewarded financially. Finally, he should hold a Champion Day regularly, say once in every other month, in which Champions (upper managers) are educated by specially invited speakers and he should discuss the progress of Six Sigma with the Champions.

It is also the responsibility of top-level management to set “stretch goals” for the Six Sigma initiative. Stretch goals are tough and demanding, but are usually achievable. Some companies set the stretch goal for process performance at 6 sigma or 3.4 DPMO for all critical-to-customer characteristics.

However, the goals can also be set incrementally, by stating instead the annual improvement rate in process performance.

The industry standard is to reduce DPMO by 50% annually.

(2) Stakeholder involvement

Stakeholder involvement means that the hearts and minds of employees, suppliers, customers, owners and even society should be involved in the improvement methodology of Six Sigma for a company. In order to meet the goal set for improvements in process performance and to complete the improvement projects of a Six Sigma initiative, top-level management commitment is simply not enough. The company needs active support and direct involvement from stakeholders.

Employees in a company constitute the most important group of stakeholders. They carry out the majority of improvement projects and must be actively involved. The Six Sigma management is built to ensure this involvement through various practices, such as training courses, project team activities and evaluation of process performance. Suppliers also need to be involved in a Six Sigma initiative.

A Six Sigma company usually encourages its key suppliers to have their own Six Sigma programs. To support suppliers, it is common for Six Sigma companies to have suppliers sharing their performance data for the products purchased and to offer them participation at in-house training courses in Six Sigma. It is also common for Six Sigma companies to help small suppliers financially in pursuing Six Sigma programs by inviting them to share their experiences together in report sessions of project team activities. The reason for this type of involvement is to have the variation in the suppliers’ products transferred to the company’s processes so that most of the process improvement projects carried out on suppliers’ processes would result in improvement of the performance.

Customers play key roles in a Six Sigma initiative. Customer satisfaction is one of the major objectives for a Six Sigma company. Customers should be involved in specific activities such as identifying the critical-to-customer (CTC) characteristics of the products and processes. CTC is a subset of CTQ from the viewpoint of the customers. Having identified the CTC requirements, the customers are also asked to specify the desired value of the characteristic, i.e., the target value and the definition of a defect for the characteristic, or the specification limits. This vital information is utilized in Six Sigma as a basis for measuring the performance of processes. In particular, the R&D part of a company should know the CTC requirements and should listen to the voice of customers (VOC) in order to reflect the VOC in developing new products.

ISO 14001 And The Environment

The ISO 14000 family of International Standards on environmental management is a relative newcomer to ISO’s portfolio – but enviroment-related standardization is far from being a new departure for ISO.
In fact, ISO has two-pronged approach to meeting the needs of business, industry, governments, non-governmental organizations and consumers in the field of the environment.
On the one hand, it offers a wideranging portfolio of standardized sampling, testing and analytical methods to deal with specific environmental challenges. It has developed more than 350 International Standards (out of a total morethan 12000) for the monitoring of such aspects as the quality of air, water and soil. These standards are means of providing business and government with scientifically valid data on the environmental effects of economic activity.
They also serve in a number of countries as the technical basis for environmental regulations.
ISO is leading a strategic approach by developing environmental management system standards that can be implemented in any type of organization in either public or private sectors (companies, administration, public utilities). To spearhead this strategic approach, ISO establish a new technical commitee, ISO /TC 207, Environmental management, in
1993. This followed ISO’s successful pioneering experience in management system standardization with the ISO 9000 series for quality management.
ISO’s direct involvement in environmental management stemmed from an intensive consultation process, carried out within the framework of a Strategic Advisory Group on Environment (SAGE),set up in 1991, in which 20 countrie, 11 international organizations and more than 100 environmental experts participated in defining the basic requirements of a new approach to environment-related standards.
This pioneering work was consolidated with ISO’s commitment to support the objective of “sustainable development” dicussed at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992.
Today, delegations of business and government experts from 55 countries have participate actively within TC 207,
and another 16 countries have observer status. These delegations are chosen by the national standars institute concerned and they are required to bring to TC 207 a national consensus on issue being addressed by the commitee.
This national consensus is derived from a process of consultation with interested parties.
From its beginning, it was recognized that ISO/TC 207 should have close cooperation with ISO/TC 176, Quality management and quality assurance, in the areas of management systems, auditing and related terminology. Active efforts are under way to ensure compatibility of ISO environmental management and quality management standards, for the benefit of all organizations wishing to implement them.

Introduction to ISO Certification

Certification is a way to attest, by the intermediary of a third-party certifier, to a company’s ability to provide a service, product or system in accordance with client requirements and regulation requirements. ISO and IEC give the following definition:
Procedure by which a third party gives written assurancethat a product, process or service complies with the requirementsspecified in a benchmark.The ISO 9000 family of standards corresponds to all the management best practices benchmarks as regards quality, which are defined by ISO (the International Organisation for Standardization).
ISO 9000 standards were originally written in 1987, with revisions taking place in 1994 and 2000. Thus, the 2000 version of the ISO 9001 standard, which is part of the ISO 9000 family, is written “ISO 9001:2000″. The ISO 9001:2000 standard mainly focuses on the processes used to produce a service or product, whereas the ISO 9001:1994 standard was mainly focused on the product itself. Here is an overview of all the different standards in the ISO 9000 family:
ISO 9000: “Quality Management Systems – Basic Principles and Vocabulary”. The ISO 9000 standard describes the principles of a quality management system and defines the terminologyISO 9001: “Quality Management Systems – Requirements”. The ISO 9001 standard describes the requirements relative to a quality management system either for internal use or for contractual or certification purposes. Therefore, this standard is a group of requirements that companies must followISO 9004: “Quality Management Systems – Guidelines for Improving Performance”. This standard, which is intended for internal use and not for contractual purposes, focuses particularly on continually improving performanceISO 10011: “Guidelines for auditing quality management and/or environmental management systems”.

Requirements for Product Environmental Quality Assurance

All Mandatory Requirements for Product Environmental Quality Assurance need to be carried out in the following manner1. Establish a system that meets all requirements2. Ensure the system is stable and efficient.3. Document the processes and procedures4. Keep records of the system’s performance.
The assigned management of the supplier shall establish a system to prevent BannedSubstances from being used in the products and packaging.(1) To determine policies and methods for ensuring Product Environment Quality.(2) To assign a person to be in charge of managing Product Environment Quality(“Product Environmental Quality Management Representative”)(3) To establish an organization in managing Product Environment Quality,determine responsibilities, authorities, roles of each department and familiarize allmembers in each department with the importance of Product Environment Quality.(4) To establish a “Cadmium-Free Factory”(5) To review the adequacy and efficiency of the system.
Maintenance of the SystemThe supplier shall maintain the system in a condition to be able to respond to therequests for Product Environment Quality and instruction letters to suppliers),ensure the system is properly functioning.(1) Plan and carry out an internal audit at least once a year.(2) When Non-conforming Products or defects are found in the system, the suppliershall conduct an internal audit immediately.(3) The assigned management for Product Environment Products at the suppliershall revise the system according to the results of the internal audit if necessary.

Why is Six Sigma Fascinating in ISO 9000?

Six Sigma has become very popular throughout the whole world. There are several reasons for this popularity. First, it is regarded as a fresh quality management strategy which can replace TQC, TQM and others.
Many companies, which were not quite successful in implementing previous management strategies such as TQC and TQM, are eager to introduce Six Sigma.
Development process of Six Sigma in quality management
Six Sigma is viewed as a systematic, scientific, statistical and smarter (4S) approach for management innovation which is quite suitable for use in a knowledge-based information society.
Second, Six Sigma provides efficient manpower cultivation and utilization. It employs a “belt system” in which the levels of mastery are classified as green belt, black belt, master black belt and champion. As a person in a company obtains certain
training, he acquires a belt. Usually, a black belt is the leader of a project team and several green belts work together for the project team.
Third, there are many success stories of Six Sigma application in well known world-class companies. As mentioned earlier, Six Sigma was pioneered by Motorola and launched as a strategic initiative in 1987. Since then, and particularly from 1995, an exponentially growing number of prestigious global firms have launched a Six Sigma program. It has been noted that many globally leading companies run Six Sigma programs (see Figure 3), and it has been well known that Motorola, GE, Allied Signal, IBM, DEC, Texas Instruments, Sony, Kodak, Nokia, and Philips Electronics among others have been quite successful in Six Sigma. In Korea, the Samsung, LG, Hyundai groups and Korea Heavy Industries & Construction Company have been quite successful with Six Sigma.
Lastly, Six Sigma provides flexibility in the new millennium of 3Cs, which are:
• Change: Changing society
• Customer: Power is shifted to customer and customer demand is high
• Competition: Competition in quality and productivity
The pace of change during the last decade has been unprecedented, and the speed of change in this new millennium is perhaps faster than ever before. Most notably, the power has shifted from producer to customer. The producer-oriented industrial society is over, and the customer-oriented information society has arrived. The customer has all the rights to order, select and buy goods and services. Especially, in e-business, the customer has all-mighty power.
Six Sigma with its 4S(systematic, scientific, statistical and smarter) approaches provides flexibility in managing a business unit.

Quality Characteristic in ISO 9000

Any feature or characteristic of a product or service that is needed to satisfy
customer needs or achieve fitness for use is a quality characteristic. When
dealing with products the characteristics are almost always technical character-
istics, whereas service quality characteristics have a human dimension. Some
typical quality characteristics are given below.

Product characteristics
1. Accessibility Functionality Size
2. Availability Interchangeability Susceptibility
3. Appearance Maintainability Storability
4. Adaptability Odour – Strength
5. Cleanliness Operability -Taste
6. Consumption Portability – Testability
7. Durability Producibility Traceability
8. Disposability Reliability – Toxicity
9. Emittance Reparability Transportability
10. Flammability Safety – Vulnerability
11. Flexibility Security – Weight

Service quality characteristics
1. Accessibility Credibility – Honesty
2. Accuracy Dependability Promptness
3. Courtesy Efficiency – Responsiveness
4. Comfort Effectiveness Reliability
5. Competence Flexibility – Security

These are the characteristics that need to be specified and their achievement
controlled, assured, improved, managed and demonstrated. These are the
characteristics that form the subject matter of the product requirements
referred to in ISO 9000. When the value of these characteristics is quantified or
qualified they are termed product requirements. We used to use the term quality
requirements but this caused a division in thinking that resulted in people
regarding quality requirements as the domain of the quality personnel and
technical requirements being the domain of the technical personnel. All
requirements are quality requirements – they express needs or expectations that
are intended to be fulfilled by a process output that possesses inherent
characteristics. We can therefore drop the word quality. If a modifying word is
needed in front of the word requirements it should be a word that signifies the
subject of the requirements. Transportation system requirements would be
requirements for a transportation system, Audio speaker design requirements
would be requirements for the design of an audio speaker, component test
requirements would be requirements for testing components, and management
training requirements would be requirements for training managers. ISO 9000
requirements are often referred to as quality requirements as distinct from other
types of requirements but this is misleading. ISO 9000 is no more a quality
requirement than is ISO 1000 on SI units, ISO 2365 for Ammonium nitrate or
ISO 246 for Rolling Bearings. The requirements of ISO 9000 are quality
management system requirements – requirements for a quality management
system.

Quality Management

There are two schools of thought on quality management. One views quality management as the management of success and the other the elimination of failure. They are both valid. Each approaches the subject from a different angle:

The ‘success’ school is characterized by five questions :
1 What are you trying to do?
2 How do you make it happen?
3 How do you know it’s right?
4 How do you know it’s the best way of doing it?
5 How do you know it’s the right thing to do?

The ‘failure elimination’ school is characterized by five different questions
1 How do you know what is needed?
2 What could affect your ability to do it right?
3 What checks are made to verify achievement?
4 How do you ensure the integrity of these checks?
5 What action is taken to prevent a recurrence of failure?

In an ideal world, if we could design products, services and processes that could not fail we would have achieved the ultimate goal. Success means not only that products, services and processes fulfil their function but also that the function is what customers’ desire. Failure means not only that products, services and processes would fail to fulfil their function but also that their function was not what customers desired. A gold-plated mousetrap that does not fail is not a success if no one needs a gold-plated mousetrap.

The introductory clause of ISO 9001:1994 contained a statement that the aim of the requirements is to achieve customer satisfaction by prevention of nonconformities. (This was indicative of the failure school of thought.) The introductory clause of ISO 9001:2000 contains a statement that the aim is to enhance customer satisfaction through the effective application of the quality management system and the assurance of conformity to customer and applicable regulatory requirements. (This is indicative of the success school of thought.)

In reality you cannot be successful unless you know of the risks you are taking and plan to eliminate, reduce or control them. A unification of these approaches is what is therefore needed for organizations to achieve, sustain and improve quality. You therefore need to approach the achievement of quality from two different angles and answer two questions. What do we need
to do to succeed and what do we need to do to prevent failure?

Quality does not appear by chance, or if it does it may not be repeated. One has to design quality into the products and services. It has often been said that one cannot inspect quality into a product. A product remains the same after inspection as it did before, so no amount of inspection will change the quality of the product. However, what inspection does is measure quality in a way that allows us to make decisions on whether or not to release a piece of work. Work that passes inspection should be quality work but inspection unfortunately is not 100% reliable. Most inspection relies on human judgement and this can be affected by many factors, some of which are outside our control (such as the private life, health or mood of the inspector). We may also fail to predict the effect that our decisions have on others. Sometimes we go to great lengths in
preparing organization changes and find to our surprise that we neglected something or underestimated the effect of something. We therefore need other means to deliver quality products – we have to adopt practices that enable us to achieve our objectives while preventing failures from occurring.

Measurement and Evaluation In ISO 14001:2004

After implementing the environmental policy, management needs to measure environmental that the data can be verified by an internal or external auditor.
interventions and their impact on the environment. This is done by building up an environmental effects register (environmental inventory). All equipment used for monitoring and measuring must be accurate and calibrated on a regular basis. To check the compliance status of an organization, additional information about regulations and other requirements is needed. A so called environmental regulations register?Eis often installed and maintained for this purpose. To obtain a better picture about the financial consequences of environmental protection, the accounting system should reflect environmental costs. Therefore, information about environmentally-induced costs and earnings needs to be collected. All this information should be recorded in such a manner.er
Environmental Performance Evaluation Accesses Environment Performance against environmental targets and objectives and against applicable environmental regulations. Responsibilities and authority need to be defined to deal with non-compliance within the EMS. This includes specifying the actions to be taken to correct an undesirable ituation and to prevent future non-compliance.
The analysis of environmental and economic performance leads to eco efficiency, the key component in sustainable business management.
The analysis of environmental and economic performance leads to eco
efficiency, the key component in sustainable business management. The recording of physical environmental data, environmental regulations and environmentally-induced financial information is necessary as a basis for effective decision making. Therefore, financial, legal and ecological data systems must be built up from scratch or adapted to the requirements of the EMS standard.

Evaluation Of Compliance Of ISO 14001 EMS

The requirement to establish a procedure for periodically evaluating compliance with applicable legal and other requirements falls short of specifically requiring regulatory compliance audits but, in fact, a system of regular regulatory compliance audits may be the most practical means for meeting this requirement of the standard. In the U.S., determination of whether to conduct a compliance audit will be governed in part by the particular jurisdiction’s approach to allowing a legal privilege for the self-assessment audit.
Evaluation vs. Audit – The difference between an evaluation and audit can only be determined by looking outside of ISO 14001. Consulting a dictionary reveals that an evaluation involves a determination of value or worth and that an audit is an examination of accounts done by persons appointed for the purpose. A better definition `is the more specific ISO 19011:2002, Guidelines for Quality and/or Environmental Management Systems Auditing, which defines an audit as a “systematic, independent, and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which the audit criteria are fulfilled.” Many organizations do not have a system for evaluating regulatory compliance other than their own records and the inspections of regulatory officials. This lack of a verification system can be a risky way to operate. Reports of enforcement actions and consent agreements show that many organizations are blindsided by rogue employees who violate rules and falsify documents to cover up environmental misdeeds. Although ISO 14001 does not prescribe a specific approach to evaluation of regulatory compliance, organizations should consider methods for going beyond verification of records by collecting and evaluating physical evidence.

Basic QC and Six Sigma Tools

The 7 QC Tools
The Seven Quality Control tools (7QC tools) are graphical and statistical tools which are most often used in QC for continuous improvement. Since they are so widely utilized by almost every level of the company, they have been nicknamed the Magnificent Seven. They are applicable to improvements in all dimensions of the process performance triangle: variation of quality, cycle time and yield of productivity.
Each one of the 7QC tools had been used separately before 1960. However, in the early 1960s, they were gathered together by a small group of Japanese scientists lead by Kaoru Ishikawa, with the aim of providing the QC Circles with effective and easy-to-use tools. They are, in alphabetical order, cause-and-effect diagram, check sheet, control chart, histogram, Pareto chart, scatter diagram and stratification. In Six Sigma, they are extensively used in all phases of the improvement methodology – define, measure, analyze, improve and control.
(1) Cause-and-effect diagram
An effective tool as part of a problem-solving process is the cause-and-effect diagram, also known as the Ishikawa diagram (after its originator) or fishbone diagram. This technique is useful to trigger ideas and promote a balanced approach in group brainstorming sessions where individuals list the perceived sources (causes) with respect to outcomes (effect).
When constructing a cause-and-effect diagram, it is often appropriate to consider six main causes that can contribute to an outcome response (effect): so-called 5M1E (man, machine, material, method, measurement, and environment).
When preparing a cause-and-effect diagram, the first step is to agree on the specific wording of the effect and then to identify the main causes that can possibly produce the effect. The main causes can often be identified as any of 5M1E, which helps us to get started, but these are by no means exhaustive.
Using brainstorming techniques, each main cause is analyzed. The aim is to refine the list of causes in greater detail until the root causes of that particular main cause are established. The same procedure is then followed for each of the other main causes. The method is a main cause, the pressure and the temperature are the causes, and “the pressure is low” and “the temperature is too high” are the root causes.
(2) Check sheet
The check sheet is used for the specific data collection of any desired characteristics of a process or product that is to be improved. It is frequently used in the measure phase of the Six Sigma improvement methodology, DMAIC. For practical purposes, the check sheet is commonly formatted as a table. It is important that the check sheet is kept simple and that its design is aligned to the characteristics that are measured. Consideration should be given as to who should gather the data and what measurement intervals to apply. For example, Figure 4.2 shows a check sheet for defect items in an assembly process of automobile ratios.
(3) Control chart
(a) Introduction
The control chart is a very important tool in the “analyze, improve and control” phases of the Six Sigma improvement methodology. In the “analyze” phase, control charts are applied to judge if the process is predictable; in the “improve” phase, to identify evidence of special causes of variation so that they can be acted on; in the “control” phase, to verify that the performance of the process is under control.
The original concept of the control chart was proposed by Walter A. Shewhart in 1924 and the tool has been used extensively in industry since the Second World War, especially in Japan and the USA after about 1980. Control charts offer the study of variation and its source. They can give process monitoring and control, and can also give direction for improvements. They can separate special from common cause issues of a process. They can give early identification of special causes so that there can be timely resolution before many poor quality products are produced. Shewhart control charts track processes by plotting data over time in the form shown in Figure 4.3. This chart can track either variables or attribute process parameters. The types of variable charts are process mean (x), range (R), standard deviation (s), individual value (x) and moving range (Rs). The attribute types are fraction nonconforming (p), number of nonconforming items (np), number of nonconformities (c), and nonconformities per unit (u).
(4) Histogram
It is meaningful to present data in a form that visually illustrates the frequency of occurrence of values. In the analysis phase of the Six Sigma improvement methodology, histograms are commonly applied to learn about the distribution of the data within the results Ys and the causes Xs collected in the measure phase and they are also used to obtain an understanding of the potential for improvements.
(5) Pareto chart
The Pareto chart was introduced in the 1940s by Joseph M.Juran, who named it after the Italian economist and statistician Vilfredo Pareto, 1848–1923. It is applied to distinguish the “vital few from the trivial many” as Juran formulated the purpose of the Pareto chart. It is closely related to the so-called 80/20 rule – “80% of the problems stem from 20% of the causes,” or in Six Sigma terms “80% of the poor values in Y stem from 20% of the Xs.”
In the Six Sigma improvement methodology, the Pareto chart has two primary applications. One is for selecting appropriate improvement projects in the define phase. Here it offers a very objective basis for selection, based on, for example, frequency of occurrence, cost saving and improvement potential in process performance.
The other primary application is in the analyze phase for identifying the vital few causes (Xs) that will constitute the greatest improvement in Y if appropriate measures are taken.
A procedure to construct a Pareto chart is as follows:
1) Define the problem and process characteristics to use in the diagram.
2) Define the period of time for the diagram – for example, weekly, daily, or shift.
Quality improvements over time can later be made from the information determined within this step.
3) Obtain the total number of times each characteristic occurred.
4) Rank the characteristics according to the totals from
(6) Scatter diagram
The scatter plot is a useful way to discover the relationship between two factors, X and Y, i.e., the correlation. An important feature of the scatter plot is its visualization of the correlation pattern, through which the relationship can be determined. In the improve phase of the Six Sigma improvement methodology, one often searches the collected data for Xs that have a special influence on Y. Knowing the existence of such relationships, it is possible to identify input variables that
cause special variation of the result variable. It can then be determined how to set the input variables, if they are controllable, so that the process is improved. When several Xs may influence the values of Y, one scatter plot should be drawn for each combination of the Xs and Y.
(7) Stratification
Stratification is a tool used to split collected data into subgroups in order to determine if any of them contain special cause variation. Hence, data from different sources in a process can be separated and analyzed individually. Stratification is mainly used in the analyze phase to stratify data in the
search for special cause variation in the Six Sigma improvement methodology.
The most important decision in using stratification is to determine the criteria by which to stratify. Examples can be machines, material, suppliers, shifts, day and night, age groups and so on. It is common to stratify into two groups. If the number of observations is large enough, more detailed stratification is also possible.

TQM and Six Sigma

While Six Sigma is definitely succeeding in creating some impressive results and culture changes in some influential organizations, it is certainly not yet a widespread success. Total Quality Management (TQM) seems less visible in many businesses than it was in the early 1990s. However, many companies are still engaged in improvement efforts based on the principles and tools of TQM. It appears at least in Korea that Six Sigma is succeeding while TQM is losing its momentum.
One of the problems that plagued many of the early TQM initiatives was the preeminence placed on quality at the expense of all other aspects of the business. Some organizations experienced severe financial consequences in the rush to make quality “first among equals.” The disconnection between management systems designed to measure customer satisfaction and those designed to measure provider profitability often led to unwise investments in quality, which has been often practiced in TQM. Ronald Snee (1999) points out that although some people believe it is nothing new, Six Sigma is unique in its approach and deployment. He defines Six Sigma as a strategic business improvement approach that seeks to increase both customer satisfaction and an organization’s financial health. Snee goes on to claim that the following eight characteristics account for Six Sigma’s increasing bottom-line (net income or profit) success and popularity with executives.
• Bottom-line results expected and delivered
• Senior management leadership
• A disciplined approach (DMAIC)
• Rapid (3–6 months) project completion
• Clearly defined measures of success
• Infrastructure roles for Six Sigma practitioners and leadership
• Focus on customers and processes
• A sound statistical approach to improvement
Other quality initiatives including TQM have laid claim to a subset of these characteristics, but only Six Sigma attributes its success to the simultaneous application of all eight. Six Sigma is regarded as a vigorous rebirth of quality ideals and methods, as these are applied with even greater passion and commitment than often was the case in the past. Six Sigma is revealing a potential for success that goes beyond the levels of improvement achieved through the many TQM efforts. Some of the mistakes of yesterday’s TQM efforts certainly might be repeated in a Six Sigma initiative if we are not careful.
A review of some of the major TQM pitfalls, as well as hints on how the Six Sigma system can keep them from derailing our efforts is listed below.
1. Links to the business and bottom-line success:
In TQM, quality often was a “sidebar” activity, separated from the key issues of business strategy and performance. The link to the business and bottom-line success was undermined, despite the term “total” quality, since the effort actually was limited to product and manufacturing functions. Six Sigma emphasizes reduction of costs, thereby contributing to the bottom-line, and participation of three major areas: manufacturing, R&D and service parts.
2. Top-level management leadership:
In many TQM efforts, top-level management’s skepticism has been apparent, or their willingness to drive quality ideas has been weak. Passion for and belief in Six Sigma at the very summit of the business is unquestioned in companies like
Motorola, GE, Allied Signal (now Honeywell), LG and Samsung. In fact, top-level management involvement is the beginning of Six Sigma.
3. Clear and simple message:
The fuzziness of TQM started with the word “quality” itself. It is a familiar term with many shades of meaning. In many companies, Quality was an existing department with specific responsibilities for “quality control” or “quality assurance,” where the discipline tended to focus more on stabilizing rather than improving processes. Also TQM does not provide a clear goal at which to aim. The concept of Six Sigma is clear and simple. It is a business system for achieving and sustaining success through customer focus, process management and improvement, and the wise use of facts and data. A clear goal (3. 4 DPMO or 6s quality level) is the centerpiece of Six Sigma.
4. Effective training:
TQM training was ineffective in the sense that the training program was not so systematic. Six Sigma divides all the employees into five groups (WB, GB, BB, MBB and Champion), and it sets very demanding standards for learning, backing them up with the necessary investment in time and money to help people meet those standards.
5. Internal barriers:
TQM was a mostly “departmentalized” activity in many companies, and it seemed that TQM failed to break down internal barriers among departments. Six Sigma places priority on cross-functional process management, and cross-functional project teams are created, which eventually breaks down internal barriers.
6. Project team activities:
TQM utilized many “quality circles” of blue-collar operators and workers, and not many “task force teams” of white-collar engineers even if they are needed. Six Sigma demands a lot of project teams of BBs and GBs, and the project team activities are one of the major sources of bottom-line and top-line success.

ISO 9000 Series and Six Sigma

ISO (International Organization for Standardization) 9000 series standards were first published in 1987, revised in 1994, and re-revised in 2000 by the ISO. The 2000 revision, denoted by ISO 9000:2000, has attracted broad expectations in industry.
As of the year 2001, more than 300,000 organizations world-wide have been certified to the ISO 9000 series standards. It embodies a consistent pair of standards, ISO 9001:2000 and ISO 9004:2000, both of which have been significantly updated and modernized. The ISO 9001:2000 standard specifies requirements for a quality management system for which third-party certification is possible, whereas ISO 9004:2000 provides guide- lines for a comprehensive quality management system and performance improvement through Self-Assessment.
The origin and historical development of ISO 9000 and Six Sigma are very different. The genesis of ISO 9000 can be traced back to the standards that the British aviation industry and the U.S. Air Force developed in the 1920s to reduce the need for inspection by approving the conformance of suppliers’ product quality. These standards developed into requirements for suppliers’ quality assurance systems in a number of western countries in the 1970s. In 1987 they were amalgamated into the ISO 9000 series standards.
Independent of ISO 9000, the same year also saw the launch of Six Sigma at Motorola and the launch of Self-Assessment by means of the Malcolm Baldrige National Quality Award in USA. Both Six Sigma and Self-Assessment can be traced back to Walter A. Shewhart and his work on variation and continuous improvement in the 1920s. It was Japanese industry that pioneered a broad application of these ideas from the 1950s through to the 1970s. When variation and continuous improvement caught the attention of some of the American business leaders in the late 1980s, it took the form of the Malcolm Baldrige National Quality Award, on a national level, and of Six Sigma at Motorola.
Some people are wondering if the ISO 9000:2000 series standards make Six Sigma superfluous. They typically refer to clause 8 of ISO 9001: “Measurement, analysis, improvement.”
It requires that companies install procedures in operations for the measurement of processes and data analysis using statistical techniques with the demonstration of continuous improvement . They also partly refer to the ISO 9004:2000 standards that embody guidelines and criteria for Self-Assessment similar to the national quality awards.
The author firmly believes that Six Sigma is needed regardless of whether a company is compliant with the ISO 9000 series. The two initiatives are not mutually exclusive and the objectives in applying them are different. A Six Sigma program is applied in organizations based on its top-line and bottom-line rationales. The primary objective for applying the ISO 9000 series standards is to demonstrate the company’s capability to consistently provide conforming products and/or services. Therefore, the ISO 9000 series standard falls well short of making Six Sigma superfluous.
The ISO 9000 series standards have from their early days been regarded and practiced by industry as a minimum set of requirements for doing business. The new ISO 9000:2000 stan
dards do not represent a significant change to this perspective. Six Sigma on the other hand, aims at world-class performance, based on a pragmatic framework for continuous improvement.
The author believes that Six Sigma is superior in such important areas as rate of improvement, bottom-line and top-line results, customer satisfaction, and top-level management commitment. However, considering the stronghold of ISO 9000 in industry, Six Sigma and ISO 9000 are likely to be applied by the same organization, but for very different purposes.

Lean Manufacturing and Six Sigma

(1) What is lean manufacturing?
Currently there are two premier approaches to improving manufacturing operations. One is lean manufacturing (hereinafter referred to as “lean”) and the other is Six Sigma.
Lean evaluates the entire operation of a factory and restructures the manufacturing method to reduce wasteful activities like waiting, transportation, material hand-offs,inventory, and over-production. It reduces variation associated with manufacturing routings, material handling, storage, lack of communication, batch production and so forth. Six Sigma tools, on the other hand, commonly focus on specific part numbers and processes to reduce variation. The combination of the two approaches represents a formidable opponent to variation in that it includes both layout of the factory and a focus on specific part numbers and processes.
Lean and Six Sigma are promoted as different approaches and different thought processes. Yet, upon close inspection, both approaches attack the same enemy and behave like two links within a chain – that is, they are dependent on each other for success. They both battle variation, but from two different points of view. The integration of Lean and Six Sigma takes two powerful problem-solving techniques and bundles them into a powerful package. The two approaches should be viewed as complements to each other rather than as equiva
lents of or replacements for each other (Pyzdek, 2000). In practice, manufacturers that have widely adopted lean practices record performance metrics superior to those achieved by plants that have not adopted lean practices. Those practices cited as lean in a recent industrial survey (Jusko, 1999) include
• quick changeover techniques to reduce setup time;
• adoption of manufacturing cells in which equipment and workstations are arranged sequentially to facilitate small-lot, continuous-flow production;
• just-in-time (JIT) continuous-flow production techniques to reduce lot sizes, setup time, and cycle time; and,
• JIT supplier delivery in which parts and materials are delivered to the shop floor on a frequent and as-needed basis.
(2) Differences between Lean and Six Sigma
There are some differences between Lean and Six Sigma as noted below.
• Lean focuses on improving manufacturing operations in variation, quality and productivity. However, Six Sigma focuses not only on manufacturing operations, but also on all possible processes including R&D and service areas.
• Generally speaking, a Lean approach attacks variation differently than a Six Sigma system does (Denecke, 1998) as shown in Figure 5.4. Lean tackles the most common form of process noise by aligning the organization in such a way that it can begin working as a coherent whole instead of as separate units. Lean seeks to co-locate, in sequential order, all the processes required to produce a product. Instead of focusing on the part number, Lean focuses on product flow and on the operator. Setup time, machine maintenance and routing of processes are important measures in Lean. However, Six Sigma focuses on defective rates and costs of poor quality due to part variation and process variation based on measured data.
• The data-driven nature of Six Sigma problem-solving lends itself well to lean standardization and the physical rearrangement of the factory. Lean provides a solid foundation for Six Sigma problem-solving where the system is measured by deviation from and improvements to the standard.
• While Lean emphasizes standardization and productivity, Six Sigma can be more effective at tackling process noise and cost of poor quality.

Seven Steps for Six Sigma Introduction

When a company intends to introduce Six Sigma for its new management strategy, we would like to recommend the following seven-step procedures:
1. Top-level management commitment for Six Sigma is first and foremost. The CEO of the corporation or business unit should genuinely accept Six Sigma as the management strategy. Then organize a Six Sigma team and set up the long-term Six Sigma vision for the company.
2. Start Six Sigma education for Champions first. Then start the education for WBs, GBs, BBs and MBBs in sequence. Every employee of the company should take the WB education first and then some of the WBs receive the GB education, and finally some of the GBs receive the BB education. However, usually MBB education is practiced in professional organizations.
3. Choose the area in which Six Sigma will be first introduced.
4. Deploy CTQs for all processes concerned. The most important is the company’s deployment of big CTQy from the standpoint of customer satisfaction. Appoint BBs as full-time project leaders and ask them to solve some important CTQ problems.
5. Strengthen the infrastructure for Six Sigma, including measurement systems, statistical process control (SPC), knowledge management (KM), database management system (DBMS) and so on.
6. Designate a Six Sigma day each month, and have the progress of Six Sigma reviewed by top-level management.
7. Evaluate the company’s Six Sigma performance from the customers’ viewpoint, benchmark the best company in the world, and revise the Six Sigma roadmap if necessary. Go to step 1 for further improvement.
First of all, a handful or a group of several members should be appointed as a Six Sigma team to handle all kinds of Six Sigma tasks. The team is supposed to prepare proper education and the long-term Six Sigma vision for the company. We can say that this is the century of the 3Cs, which are Changing society, Customer satisfaction and Competition in quality. The Six Sigma vision should be well matched to these 3Cs. Most importantly, all employees in the company should agree to and respect this long-term vision.
Second, Six Sigma can begin from proper education for all classes of the company. The education should begin from the top managers, so called Champions. If Champions do not understand the real meaning of Six Sigma, there is no way for Six Sigma to proceed further in the company. After Champion’s education, GB BB MBB education should be completed in sequence.
Third, we can divide Six Sigma into three parts according to its characteristics. They are R&D Six Sigma, manufacturing Six Sigma, and Six Sigma for non-manufacturing areas. The R&D Six Sigma is often called DFSS (Design for Six Sigma). It is usually not wise to introduce Six Sigma to all areas at the same time. The CEO should decide the order of introduction to these three areas. It is common to introduce Six Sigma to manufacturing processes first, and then service areas and R&D areas. However, the order really depends on the current circumstances of the company.
Fourth, deploy CTQs for all processes concerned. These CTQs can be deployed by policy management or by management by objectives. Some important CTQs should be given to BBs to solve as project themes. In principle, the BBs who lead the project teams work as full-time workers until the projects are finished.

What is Six Sigma?

Sigma (s ) is a letter in the Greek alphabet that has become the statistical symbol and metric of process variation. The sigma scale of measure is perfectly correlated to such characteristics as defects-per-unit, parts-per-million defectives, and the probability of a failure. Six is the number of sigma measured in a process, when the variation around the target is such that only 3.4 outputs out of one million are defects under the assumption that the process average may drift over the long term by as much as 1.5 standard deviations.
Six Sigma may be defined in several ways. Tomkins (1997) defines Six Sigma to be “a program aimed at the near-elimination of defects from every product, process and transaction.” Harry (1998) defines Six Sigma to be “a strategic initiative to boost profitability, increase market share and improve customer satisfaction through statistical tools that can lead to breakthrough quantum gains in quality.”
Six Sigma was launched by Motorola in 1987. It was the result of a series of changes in the quality area starting in the late 1970s, with ambitious ten-fold improvement drives. The top-level management along with CEO Robert Galvin developed a concept called Six Sigma. After some internal pilotm implementations, Galvin, in 1987, formulated the goal of
“achieving Six-Sigma capability by 1992” in a memo to all Motorola employees (Bhote, 1989). The results in terms of reduction in process variation were on-track and cost savings totalled US$13 billion and improvement in labor productivity achieved 204% increase over the period 1987–1997 (Losianowycz, 1999). In the wake of successes at Motorola, some leading elec-
tronic companies such as IBM, DEC, and Texas Instruments launched Six Sigma initiatives in early 1990s. However, it was not until 1995 when GE and Allied Signal launched Six Sigma as strategic initiatives that a rapid dissemination took place in non-electronic industries all over the world (Hendricks and Kelbaugh, 1998). In early 1997, the Samsung and LG Groups in Korea began to introduce Six Sigma within their companies. The results were amazingly good in those companies. For instance, Samsung SDI, which is a company under the Samsung Group, reported that the cost savings by Six Sigma projects totalled US$150 million (Samsung SDI, 2000a). At the present time, the number of large companies applying Six Sigma in Korea is growing exponentially, with a strong vertical deployment into many small- and medium-size enterprises as well.
As a result of consulting experiences with Six Sigma in Korea, it was believed that Six Sigma is a “new strategic paradigm of management innovation for company survival in this 21st century, which implies three things: statistical measurement, management strategy and quality culture.” It tells us how good our products, services and processes really are through statistical measurement of quality level. It is a new management strategy under leadership of top-level management to create quality innovation and total customer satisfaction. It is also a quality culture. It provides a means of doing things right the first time and to work smarter by using data information. It also provides an atmosphere for solving many CTQ (critical-to-quality) problems through team efforts.
CTQ could be a critical process/product result characteristic to quality, or a critical reason to quality characteristic. The former is termed as CTQy, and the latter CTQx.

Why is Six Sigma Fascinating in ISO 9000?

Six Sigma has become very popular throughout the whole world. There are several reasons for this popularity. First, it is regarded as a fresh quality management strategy which can replace TQC, TQM and others.
Many companies, which were not quite successful in implementing previous management strategies such as TQC and TQM, are eager to introduce Six Sigma.
Development process of Six Sigma in quality management
Six Sigma is viewed as a systematic, scientific, statistical and smarter (4S) approach for management innovation which is quite suitable for use in a knowledge-based information society.
Second, Six Sigma provides efficient manpower cultivation and utilization. It employs a “belt system” in which the levels of mastery are classified as green belt, black belt, master black belt and champion. As a person in a company obtains certain
training, he acquires a belt. Usually, a black belt is the leader of a project team and several green belts work together for the project team.
Third, there are many success stories of Six Sigma application in well known world-class companies. As mentioned earlier, Six Sigma was pioneered by Motorola and launched as a strategic initiative in 1987. Since then, and particularly from 1995, an exponentially growing number of prestigious global firms have launched a Six Sigma program. It has been noted that many globally leading companies run Six Sigma programs (see Figure 3), and it has been well known that Motorola, GE, Allied Signal, IBM, DEC, Texas Instruments, Sony, Kodak, Nokia, and Philips Electronics among others have been quite successful in Six Sigma. In Korea, the Samsung, LG, Hyundai groups and Korea Heavy Industries & Construction Company have been quite successful with Six Sigma.
Lastly, Six Sigma provides flexibility in the new millennium of 3Cs, which are:
• Change: Changing society
• Customer: Power is shifted to customer and customer demand is high
• Competition: Competition in quality and productivity
The pace of change during the last decade has been unprecedented, and the speed of change in this new millennium is perhaps faster than ever before. Most notably, the power has shifted from producer to customer. The producer-oriented industrial society is over, and the customer-oriented information society has arrived. The customer has all the rights to order, select and buy goods and services. Especially, in e-business, the customer has all-mighty power.
Six Sigma with its 4S(systematic, scientific, statistical and smarter) approaches provides flexibility in managing a business unit.
