Six Sigma Training

Six sigma was once reserved for the largest corporations in the world. During the last few years, six sigma has moved to mid-size and small organizations seeking a way to improve their business. Some of these companies employ a single six sigma black belt to produce project results.

Six sigma has now become so popular there are thousands of job openings for green belts, black belts, and master black belts. As a result of this huge job market, there are now hundreds of six sigma training courses and seminars.

One major focus of six sigma is the reduction of variation. The ironic fact is that six sigma training courses have huge variation, the very characteristic the discipline attempts to minimize.

A recent look at green belt courses at a few major universities looked like the difference between algebra and geometry.

Master Black Belt courses also had extreme variation – some teach the black belt to instruct six sigma, while others have an in depth study of just a few areas, such as Design of Experiments or Design for Six Sigma. This variation does not help companies when seeking a Master Black Belt.

The six sigma training landscape is such that the student must determine their needs prior to taking a course. This is difficult, especially at the green belt level. Many students aren’t even sure what six sigma is – they just know it’s in high demand.

The problem with a short six sigma learning period is the body of knowledge required is very large, and most people simply cannot absorb all of it by attending a few week course.

Online courses have several advantages and a few disadvantages. Six sigma online courses can offer a larger and longer course since no travel or instructor is involved. Live instructors cannot afford to deliver a 10 – 16 week course. Online courses generally have a liberal time limit.

Live courses have the disadvantage of necessary travel time and costs. The advantage is the one-on-one contact, although it’s for a brief period.

Regardless of which type of course is taken, anyone pursuing a six sigma training course should obtain a good collection of books for reference. The depth and instruction within books varies as widely as training courses. Therefore, most practicing black belts have quite a collection of reference materials.

It is also important to determine the type of instruction before taking the course. Most companies are not doing six sigma for the fun of it. They want impact, which in laymen’s terms is financial gain. If a course only teaches the tools and methods behind six sigma the student is only learning a portion of the skills needed to be successful.

It is the use of the tools that will ultimately determine success. For example, anyone can learn Failure Mode and Effects Analysis (FMEA), Design of Experiments (DOE), and hypothesis testing for equal means and variances. The successful black belt knows which tool to use and when to use it. There are simply too many tools to apply them all and hope something is gained.

How Lean Six Sigma Can Bring Quality And Efficiency To Firms

To ensure the success of lean Six Sigma implementations, the project manager should not only have the requisite Six Sigma qualifications and training, but should also have knowledge about the basics of Lean 6 Sigma. Given below are some of the basics of Lean 6 Sigma, which are applicable to manufacturing firms that are in the process of implementing Lean Six Sigma.


Data Authenticity


Even the most advanced computerized systems installed in an organization will not be effective as long as the data or information that is used as input is incorrect. This is why it is necessary to concentrate efforts on gathering genuine data relevant to the needs and requirements of a particular Lean 6 Sigma improvement initiative.


Managing Performance


Lean Six Sigma implementation projects require team effort. If a team were strained with the personal egos of individual team members, it would become quite difficult to achieve the desired results in time. The project manager should continuously try to motivate team members to contribute their efforts towards the achievement of common Lean 6 Sigma goals and objectives.


Production System


Lean 6 Sigma lays stress on employing sequential production techniques, rather than depending on the obsolete shop scheduling production technique. The fact that sequential production techniques are quite effective is easily evident from the use of such techniques by manufacturing behemoths. This however does not imply that this technique is only beneficial for large corporations. Small and medium sized enterprises can also derive the same benefits from this new production methodology.


Effective Logistics


Lean 6 Sigma stresses building a simple yet effective logistical platform that helps in reducing inventory-carrying costs, while improving efficiency at the same time. Such a logistical system is characterized by continuous flow of raw materials and finished goods from point A to point B.


Cycle Time Management


Lean 6 Sigma methodologies stress reducing long cycle times, which are a reflection of inefficient manufacturing processes and excessive non-value-added costs. The focus is on eliminating the root cause of extended cycle times, rather than devising short-term solutions.


Linear Production Model


Lean Six Sigma stresses designing a production model that can be configured as and when needed, depending on the existing demand. It should be flexible so that the production can be decreased or increased according to seasonal variations, without affecting the quality of the end product.


Timely Decisions


To make the most of what the market has to offer, manufacturing firms need to be proactive in making essential strategic decisions, such as when to downsize and when to start recruiting. A timely decision is one of the main factors that make the difference between a lost opportunity and increased profitability. Lean Six Sigma is beneficial because it helps in making timely business decisions.


Having knowledge about the above stated Lean Six Sigma basics will help project managers to complete the implementations successfully and within the specified planned period. It will also help in ensuring the long-term sustainability of the implemented Lean Six Sigma project.

Team Building

BUILDING SUPERVISOR TEAMS:

A CASE STUDY


BACKGROUND TO THE PROJECT


In June 1999, I was contracted to lead a twenty-four hour team-building intervention with a group of twenty Managers, Supervisors, Lead personnel, and journeyman production employees of a major truck body manufacturer. This privately held company was founded in 1971 and is guided by its President and a General Manager who began as a shop floor laborer, and worked his way up the organizational ladder to his present position. Operating in three shifts, the 200-person company has 150,000 square feet of manufacturing, warehouse and office space in Southern California, and is the largest service body company in the western United States. Its clients include Ford and Chevrolet. My involvement was requested because of the need to design and deliver training in both Spanish and English. Audience characteristics are discussed in more detail, below.

This effort was a partnership between the California Manufacturing Technology Center (C.M.T.C.), based in Hawthorne, California, the Center for Economic Development at West Los Angeles College, and the Employment Training Panel, State of California, which funded the project. This author and C.M.T.C. identified the client’s main needs to be:


-Significant growth in production capacity and financial performance, especially during the last 2-3 years. This rapid growth has given rise to thousands of hours of overtime to meet customer demand; an increased accident rate; difficulty in recruiting skilled workers, particularly in the Fabrication Department; a “firefighting” approach to problem-solving and decision-making by management, which is mirrored throughout the organization; and unexpected stresses on equipment, machinery, and work processes. These stresses, in turn, have generated production bottlenecks and contributed to the “management by crisis” atmosphere of the plant.

-A stable workforce (see Table 1, below) who were reluctant, according to C.M.T.C., to adopt the new technology and work processes required by Lean Manufacturing. For example, a manufacturer’s representative who regularly services the plant as an account, reported that “veteran” workers resist learning new requirements, processes and materials, because of they feel their present their present technology and methods for painting truck bodies technology and processes they know well are adequate.

-A lack of reliable means to measure the actual amounts of scrap and re-work produced.

-Unpredictability of job scheduling associated with changing customer requirements and sporadic Company use of reliable scheduling tools.

-Re-occurring production bottlenecks on the shop floor, particularly with regard to the line producing their standard (vs. custom) products.

-Organizational “firewalls” between certain units and departments (e.g., Standard vs. Cargo vs. Sport production lines) that result in production and organizational inefficiencies. For example, the customized jigs and fixtures designed and built by a company Engineer for the particular requirements of one production line, could be effectively adapted for use on other production lines. However, production inefficiencies resulted from employee resistance to adapt or combine this customized equipment with the older equipment, used on other production lines.


Given these issues, management decided to act. Seeking to grow market share and to continue to build its long-term customer base, the company contracted with C.M.T.C. to prepare for the formation of a cross-functional (e.g., Production, Purchasing, Accounting, Engineering, etc.) team of 5-6 people. This team, to be selected from the group of 20 training participants, would lead continuous improvement efforts at this company. More particularly, the team would use Lean Manufacturing technology to identify and resolve issues associated with one particular product line. This core team would, in turn, guide the formation of other teams from the shop floor, whose representatives were participating in this training.


Successful implementation of Lean Manufacturing depends on building effective work teams. My role in this process was to design and conduct a series of six, four-hour team-building workshops, over a three-week period, that would lay the groundwork for subsequent Kaizen events. Following my work, a bi-lingual Kaizen consultant from the C.M.T.C. would follow-up with sixteen hours of intensive training in Lean Manufacturing. At the conclusion of the six-week training, the client would begin working together in using newly acquired skills to identify and resolve issues for continuous improvement.


THE AUDIENCE


The outstanding characteristic of this training group was its cultural and linguistic diversity. Of the twenty participants, only four were native English-speakers. All other participants were native Spanish-speakers, from Mexican ancestry. The plant Manager and two other Supervisors, who are of Mexican decent, speak and read English fluently. The remaining 12-13 Spanish-speaking participants were uncomfortable with both written and oral English. An estimated 20% of these Spanish-speakers experienced difficulty in reading and writing Spanish.


There were also important differences in cultural values and assumptions that were reflected in the training design, and training materials. These related to such issues as: how time at work should be used, how power and authority should be exercised, how day-to-day relationships between peers should be carried out, the appropriate exercise of discipline, perceptions about the formal and informal reward systems, how much participation in decision-making and problem-solving is appropriate and desirable for hourly employees, etc.


For example, many hourly wage-roll participants in these team-building meetings openly expressed reluctance to “intrude” on the decision-making responsibilities of their bosses a common feature of work relationships in Latin American cultures. To become involved in decision-making and problem solving is perceived as a management role, and sharing power and authority was commonly seen by most participants as a sign of weakness, and undesirable. The openness and trust that productive work teams require was frustrated by a Latin cultural perspective that emphasizes the solitary nature of the human being, and his or her essential and necessary isolation from non-family members. For a definitive discussion on this point, the reader may wish to consult the work of the Mexican author, Octavo Paz, in his seminal work, The Labyrinth of Solitude (1).


LESSONS LEARNED


Training design and materials needed to reflect these data. Therefore, the training design and presentation of the material emphasized these points:

1.Build trust. In Spanish, the word “‘confianza’” is loosely translated as “trust.” Velásquez’ New Revised Spanish-English Dictionary (1974) also translates this word as “honest boldness, ” “assurance,” “firmness of opinion,” as well as describing a relationship that permits a certain secretiveness and privacy. As is generally well known, it is normative in Latin America for “confianza” to play a large role in shaping interpersonal relationships. It is also an important mitigating factor in working and organizational relationships. This certainly extends to the training arena: if ‘confianza’ is not earned and present – both among training participants and between trainees and instructor – trainees will “shut down” and learning will dramatically suffer. The usual repertoire of training tools to elicit participation and involvement will likely fail when ‘confianza’ is not present. This is particularly relevant for interpersonal communications skills training where such concepts and skills as providing relevant feedback, active listening, and self-disclosure are not only highly valued as elements of training design and delivery, but indeed are deemed by most training practitioners as fundamental to this type of training.


Therefore, the instructor’s ability to gain and maintain ‘confianza’ with the group is critical, and he or she should avoid behaviors that participants may interpret as confrontational. In virtually all Hispanic cultures, interpersonal confrontation is considered negative and potentially destructive – it is likely to be viewed as a personal challenge and an exercise of power and dominance. It does not have an “up” side, and is not valued for its own sake. U.S trainers, however, are much more accepting of confrontation, who see it as tool that can be brought to bear to resolve conflicts and differences.


Among the most effective ways to bridge the gap between these two worldviews is to consistently “model” trust-building behaviors during training, and to avoid situations, at least in the beginning, that participants consider confrontational. This often means that training is at a “slower” pace than it would be with non-Hispanic audiences – in other words, it takes a little longer to accomplish training goals. This author’s experience is that a typical “soft” skills training program is lengthened by a factor of about 20% because of these factors.


2.Stress basic skills. The training design provided many opportunities to practice new skills (e.g., active listening, conflict-resolution, problem solving in teams, decision-making approaches, etc.). Where in another training situation I might give two to three practice opportunities to learn a concept or skill, here I used anywhere from five to six or even seven opportunities to teach active listening skills, for example.


3.Minimize reading and writing. While each participant was provided a workbook of materials relevant to each training module (i.e., managing change in the workplace; interpersonal communications skills; team-building; and problem-solving in teams), it became apparent on the first day of training that most participants were struggling to understand workbook materials. Therefore, written materials and exercises were subsequently used only to reinforce concepts, case studies, role-plays and other exercises that could be verbally presented, demonstrated, and practiced.


4.Formalize Discussion. Hispanic cultures generally value politeness and formality in interpersonal relations, compared to North Americans. These values permeate virtually all facets of daily life. For example, whereas North Americans tend to generally appreciate frankness and openness in interpersonal relationships, it is safe to say this is not generally the case with Spanish-speakers who view directness as potentially confrontational and disrespectful. Therefore, training presentations, role-plays, simulations, group discussions and all the other tools available to the trainer should reflect and demonstrate these differences in cultural views. This is probably best accomplished by: (1) verbally acknowledging these differences, with the training audience; (2) making clear to participants the training objectives of the course, and what particular challenges may be posed by training.


5.Aim for clarity. The circumstances outlined above reinforce the importance and utility of being unambiguous and clear in giving directions, setting-up classroom practice opportunities, asking for participation in exercises, etc. I found that this audience required that the objectives and methods for each exercise, each small group discussion, each training intervention be discussed beforehand, and in more depth than otherwise might be required with a group of monolingual English-speaking participants.


6.Teach a common “vocabulary.” Participants had no shared sets of effective interpersonal skills that they could apply to working together. Cultural and language differences exacerbated this situation. Orders, requests, memoranda, and indeed virtually all other communications from management first had to be interpreted from English to Spanish and “filtered” down to the non-English-speaking employees on the shop floor, through bilingual supervisors and lead personnel. Inevitably, communication effectiveness suffered. This interpreting of data and communications resulted in loss of efficiencies and effectiveness that, in a monolingual work environment, would likely not have occurred.


7.Practice-practice-practice. Use many real-life examples to make a point and teach a skill. While using examples to train is recommended for virtually any training situation, in this circumstance it was advisable to minimize the use of analogies or examples that participants would probably consider to be too abstract; that is, the examples used were all from manufacturing and production, and were situations involving production Leads and Supervisors.


8.Reward performance immediately. It was particularly important to be on the lookout for and immediately reward participants who made honest efforts to learn. Because most participants were unsure of and naïve to this training material, any trainee performance that approximated or that accurately reproduced the desired behavior (e.g., effective listening) was promptly rewarded by verbal prompts and specific expressions of approval. For example, when John, a Foreman, accurately demonstrated active listening with others in the group, I said to the group, “John, you really summarized Joe’s point very well. That’s a great example of using active listening;” or, “Did anyone notice how Justin used ‘clarification’ to better understand what Juan was saying? Justin, can you repeat exactly how you used the clarification technique with Juan just now?”


9.Mix it up. Depending on audience readiness, mood, level of interest, and expressed desires, I used both Spanish and English interchangeably during training sessions. For example, I wrote key points on the flipchart in English, and summarized them in Spanish; or, I conducted one role-play in English, and another in Spanish. Other techniques were to:

produce key workbook materials and job aids in both languages. Encourage bilingual participants to summarize key points for their monolingual colleagues, and;

10. Invite trainees to participate in either English or Spanish, with the proviso that either they, a colleague, or I would immediately translate the substance of their remarks to others.


RESULTS FROM TRAINING


Was training successful? Impacts of this program should be measured after implementation of the total package including the Kaizen interventions. At that point, it will be possible to indirectly evaluate the extent to which these training sessions resulted in application of these skills to shop floor situations. Why only indirectly evaluate impacts? Because, to draw causal relationships between this training and improved workplace behaviors, the effects and influence of the Kaizen events would have to be eliminated, or considered. Given the present state of evaluation technology this does not seem possible now.


Written evaluations of each session asked to what degree trainees learned new skills. On average, eighty percent of trainees responded that they had acquired the targeted skills and knowledge in that training session. The training group, the Kaizen instructor and C.M.T.C. independently agree that this first effort has given the necessary impetus forward for Kaizen to begin and to be successful.

The History And Development Of Six Sigma

A question that is often asked is “was Six Sigma developed as a competitor to the existing systems?” But in reality, this question is groundless because Six Sigma was developed independently, like every other quality management system. However, if it pays to have more than one quality management system, then why not develop another system in addition to the existing ones?


So let’s see how Six Sigma evolved and eventually went on to become one of the most commendable quality management systems on the globe.


The Early Saga


The roots of Six Sigma can be traced back to the early industrial era, during the eighteenth century in Europe. Carl Frederick Gauss introduced it as a conceptual normal curve metric. The evolution of Six Sigma took one step ahead with Walter Shewhart showing how three sigma deviations from the mean required a process correction. Later in 1980, Six Sigma got a definitive form when a Motorola engineer coined the term Six Sigma for this quality management process. Motorola not only implemented this system in their organization, but they copyrighted it as well.


The Japanese Connection


Japanese people are known to have crossed many boundaries to perfect their technological achievements. So it was no wonder when they took it upon themselves to perfect the Six Sigma concept in true Japanese style. It all began when they took over a television-manufacturing unit of Motorola in 1970. The new management decided to change the way the operations were conducted. The Japanese management made sure that they placed a high emphasis on all the activities leading to production. Finally, because of their zealous approach they started manufacturing T.V sets with just 5% defects against the original records under Motorola.


Motorola’s Valuable Augmentation


The study regarding the evolution of Six Sigma would be incomplete without mentioning the valuable contribution from Motorola. Bill Smith, along with Mikel Harry, had written and codified a research report on the new quality management system that emphasized the interdependence between a product’s performance in the market and the adjustments required at the manufacturing point.


The report clearly indicated that the lesser the number of non-conformities at each stage of production, the better is the performance. This report was no less than a revolution because it paved the way for the implementation of the “logical filters” as a key tool to solve problems. Bob Galvin, the then CEO of Motorola became a leader in this system, and with his help later this four stage logical filter became the skeleton of the present day Six Sigma. The four stages were known as Measure, Analyze, Improve and Control.


Inception Of A New Road Map


Motorola’s corporate policy committee started setting goals for further improvisation of this process. They even went to the extent of declaring that by giving way to the improvisation in Six Sigma, they would achieve ten times betters quality.


Other Unforgettable Significant Contributions


There were many people, but the most prominent among them are Unisys Corp in 1988 and Asea Brown Boveri in 1993. In fact, Asea Brown Boveri gave Six Sigma its final finishing touch by putting emphasis on customer satisfaction.

Managing Costs with Six Sigma

The formula for calculating profit is really quite simple; the total earnings of the business minus the expenditures of the business (employee wages, materials, office space, etc.) equals the total profit for the year.


Obviously, there are several ways in which that profit margin can increase. One way is by increasing the amount of revenue that the business brings in. This is nice and it’s also the goal of steps such as advertising; bring in more sales and the profits go up.


Unfortunately, generating extra business and sales will not always mean an increase in profit. Think about this; the more business that comes in, the more product needs to be created in order to be sold. The more product being manufactured, the greater the chance of defects. This chain of events is what is at the heart of the Six Sigma business plan; costs are managed by decreasing defects within the production system.


What Exactly Is Six Sigma?


As stated above, the fundamental underpinnings of the Six Sigma system is increasing profit by eliminating defects. It’s a system that was created by the Motorola company back in the 1980s, built on proven processes that had been developed in other industries.


The Six Sigma system is specifically applied to the goods produced by a company. In Motorola’s case, electronic goods were the product wherein the manufacturing process was analyzed through six different steps, with the idea being to reduce defects within the products to 3.5 per one million units produced. Obviously achieving this goal would help greatly in managing the overhead costs of many different businesses, as each unit that came out perfect was a unit perfectly suited for sale.


Six Sigma in Motion


One of the most important parts of the Six Sigma program is its implementation, specifically through different roles. Like many modern business ideas. Six Sigma has some well defined roles that come with titles that may sound unusual to the unindoctrinated. Let’s take a very brief look at the titles and their roles within the implementation process.


-Executive leadership. These people are the power players within the company; CEOs and others with the power to put a vision into motion for the entire company. In addition to getting the ball rolling, they also empower other roles in their implementation process.


-Champions. Upper management makes up the majority of the champion roles, and it is here that the Six Sigma program begins to truly be implemented across a company. The champions will integrate Six Sigma planning across the company and will also serve to train black belts.


-Master Black Belts. These people are essentially the coaches of the Six Sigma system, the people who understand the process inside and out. They train the other “belts” and their sole role within the company is the implementation of Six Sigma processes.


-Black Belts. These individuals are responsible for executing the programs which are part of Six Sigma. Like the Master Black Belts, they devote all of their time to the Six Sigma process.


-Green Belts. At this level, individuals are responsible both for Sigma Six implementation and their usual job roles.


-Yellow Belts. These employees have been exposed and trained to some degree in Six Sigma but have not yet completed a program. They are not expected to actively engage in improvement of quality activities that are part of the process.


The key to a successful Six Sigma integration within a company is a well defined plan with personnel that are on board. The successful implementation of the process will help to manage costs through the elimination of defects.
