Whaddaya Think?
1. The Toyota Production System -- a formidable competitive weapon by Toyota --
consists of both Lean and Six Sigma principles and tools.
2. Six Sigma tends to get faster business results than Lean.
3. General Electric, well-known for its Six Sigma program, does not do any Lean.
4. The “Just-In-Time” process improvement craze of the 1980s was actually a
combination of Lean and Six Sigma.
5. Lean and Six Sigma are used best in a manufacturing environment, not in a service
environment.
6. Lean and Six Sigma both share the common goal of improved operational
performance, they merely go about it in different ways.
7. Jack Welch of General Electric fame first improved processes with Six Sigma, then
modified the corporate culture to make Six Sigma results sustainable.
8. The average weight of a Lean practitioner is 22 pounds less then his Six Sigma
counterpart.
9. Purist Lean and purist Six Sigma practitioners are often at odds with each other in
companies that have been doing serious process improvement for 10 years or so.
10. The learning curve for Lean tends to be greater than the learning curve for Six Sigma.
At this point it’s not expected that you know anything about disciplines of Lean, Six Sigma, or their combined method. But you must
have heard something, so get with a partner and take a shot at the T/F questions below, and then we’ll discuss in a learning environment.

Players
Player Roles & Responsibilities Typical Training Six Sigma Dedication
Black Belt Works with a team – usually of Green Belts and people with no LSS training -- assigned to
a specific LSS improvement project. Black Belts help with both the technical aspects (e.g.,
statistical tools) and people issues (e.g., team dynamics and change management).
Typically a Black Belt will deliver about $1 million to the bottom line annually.
4 weeks of training
spread over 4 months
Full-time
(18 to 24 mo)
Master Black Belt Acts as instructor, coach and mentor to several Black Belts. Frequently Master Black Belts
(MBBs) become involved in large-scale organizational change efforts and promotion of
LSS within the organization. In many organizations MBBs organize into a learning group
in which they challenge, advise, and support each other and Black Belts. They also often
formulate business strategies with top management. In addition they may also lead “super-
projects” that are high impact staffed with multiple Black Belts.
Usually on the job Full-time
Green Belt Participates in LSS by collecting data, providing process expertise, completing
improvement tasks, and communicating changes to colleagues.
3 sessions of 3-4 days Part-time, as project needs
dictate
Champion (Executive) Provides business guidance to teams, assists in selecting projects, acts as an organizational
“evangelist” for Six Sigma, allocates resources, questions the team, anticipates and
prevents problems with the LSS before they occur, removes roadblocks if they do occur.
5 days Part-time,
as active executive sponsorship
needs dictate
Executive
Sponsor
Actively supports and encourages project teams, participates in LSS meetings,
demonstrations, and celebrations.
1-2 days Part-time,
as executive support needs
dictate
Process Owner Ensures high quality design and peak performance of business processes. Helps triage
problems as those addressable by simple process improvement methods or problems
requiring use of complex, lesser-known statistical tools.
1 week Half-time to full-time,
depending on process size
17
Who you gonna call?
1. The Purchasing analyst cannot spend as much time on the cross-
departmental New Product Launch process because her functional
manager has put her on a “crunch project” in Purchasing. This will
likely cause a 4-week slip in the launch of the next product.
2. Data needs to be collected on the number of failures of your
company’s new electric razor once it gets into a customer’s hands.
3. The process improvement project will now be delayed 5 months
because the engineer on the project has been sent on an overseas
assignment.
4. Some heavy statistical analysis and design of experiments need to be
done for the new bioreactor in the South building because its yields are
erratic, and averaging only 35%.
5. Several Black Belts are working on similar problems in different parts
of the company, but they are not benefiting from each others’
experience like they could.
6. Decide that it would be great if the CEO could mention Lean Six
Sigma in each of her company-wide addresses over the next two
months.

21
What it’s not
In helping to define what Lean Six Sigma is, it is also helpful to consider what it is not:
• It is not just a collection of tools that people can be trained in and shortly thereafter deliver
outstanding results. Successful LSS efforts require strong management support, training, and formal
ties to the organization’s management system.
• It is not just a statistics program. It is a results program.
• It is not a recycled Total Quality Management program from the 1970s. While many tools and some
methods from the quality movement are present in LSS, it distinguishes itself by having formal links
to the compensation system, financial screening of potential projects, and a fanatical emphasis on the
needs of the external customer.
• It is not a training program, as many Total Quality Management programs became. It is a system of
tools, principles, and management practices that are applied to a improve processes.

Hit performance issues on
multiple fronts
• Lean training for all managers and supervisors
• Basic Six Sigma training for all managers and supervisors
• Center of Excellence leaders – located in all departments -- trained in
advanced Six Sigma methods and philosophy
• Leadership development occurred simultaneously to address critical
change management issues within, and among departments
25
Operating Results
• Representative issues addressed
– Batch review cycle time reduced by 60%
– Operational metrics track 12 parameters, improvements in 9 so far
– Yields improved by 20% in one production area by using
statistical tools
• Approach to addressing the issues and results
– All work was done via chartered, cross-functional teams
– DMAIC (Define, Measure, Analyze, Improve, Control)
26
The 10 Big “pay attention to” elements
for LSS leaders
1. The use of data and facts – not just opinions -- to make decisions.
2. Managing variation in processes, instead of just managing reject levels for a product.
3. An awareness of, and management of business processes and value streams that cut across
functional department boundaries.
4. Opportunities to pull work through operations rather than push them.
5. An emphasis on prevention, not reaction.
6. Processes and culture that foster the continual search for ways to streamline and eliminate waste.
7. Impacts of activities and solutions on customer requirements.
8. Checks and balances to ensure that LSS experts do not become overloaded and leave.
9. Workplace orderliness and cleanliness.
10. Links between LSS improvement efforts and the organization’s reward and recognition system.

Background
• Key challenges
– High rate of field failures needed to be addressed in order to compete and be profitable
– Lack of consistency within our products as a whole based on different services
– Different processes created unnecessary confusion and significant difficulties when it was time to transfer
products into large volume production
– Absence of motivation for continuous improvement outside the internal total quality group
– Goals among different departments were not aligned and people were working on redundant, and in some cases
counter-productive projects
– Many of the employees had come up through the scientific ranks and were accustomed to working alone, not on
teams.
• Results
– Successfully integrated Lean, Six Sigma, and High Performance Organization disciplines
– Operating results:
• $400,000 repeating annual savings within 2 months
• Productivity increase of 2x within 7 months
• Established a culture that drove for execution and continual improvement
• Identified key areas for upstream new product development that later saved the company over $1 million
annually
• Value-Added Process Time/Total Process Time went from 8% to 60% for two key processes within the
first 2 months
– Executives played a key role in the initial success
– Hard/soft integration principles deployed.

Lessons Learned
Planning
• Being realistic is quite helpful
• Ensuring wide participation in the planning processes
• Missing the customer perspective early on will kill you
• Need to document planning phase well
• Assign responsibilities clearly
• Integration of hard and soft aspects is key – each covers inherent weaknesses of the other
• No organization-wide roll-outs of Six Sigma without training senior managers how to support it –
top management dialogue can’t stop after the approval and initial re-organization into teams.
• Resist the temptation to use good -- not great -- performers as driving change agents, such as Black
Belts.
• Go for lean manufacturing techniques before Six Sigma to demonstrate quick wins unless data for
analysis already exists (as it did for a field service warranty process)
• Strive to “over-communicate” and request feedback on the content and quality of communication.
36
Lessons Learned
Implementation
• Maintain flexibility in the planning that other options can be considered as you move forward.
• You can generally do more than most people think.
• Ensure responsibilities are clearly assigned.
• Ensure leaders of change are optimistic and will push project through to completion.
• Groom the subsequent leaders
• The restructuring into teams -- this can not be a pilot.
• Executives need to agree on their individual and collective areas of responsibility for business processes.
• Design structures and processes that ensure control.
• Training for new leaders needs to mandatory, not optional
• Bring Finance and HR into the process soon.
• Executive efforts can decrease as the transformation progresses if the soft elements of HPO are successfully anchored.
• It is extremely important to provide frequent status reports for the improvement projects.

    28 Background • Key challenges –High rate of field failures needed to be addressed in order to compete and be profitable – Lack of consistency within our products as a whole based on different services – Different processes created unnecessary confusion and significant difficulties when it was time to transfer products into large volume production – Absence of motivation for continuous improvement outside the internal total quality group – Goals among different departments were not aligned and people were working on redundant, and in some cases counter-productive projects – Many of the employees had come up through the scientific ranks and were accustomed to working alone, not on teams. • Results – Successfully integrated Lean, Six Sigma, and High Performance Organization disciplines – Operating results: • $400,000 repeating annual savings within 2 months • Productivity increase of 2x within 7 months • Established a culture that drove for execution and continual improvement • Identified key areas for upstream new product development that later saved the company over $1 million annually • Value-Added Process Time/Total Process Time went from 8% to 60% for two key processes within the first 2 months – Executives played a key role in the initial success – Hard/soft integration principles deployed.

    35 Lessons Learned Planning • Beingrealistic is quite helpful • Ensuring wide participation in the planning processes • Missing the customer perspective early on will kill you • Need to document planning phase well • Assign responsibilities clearly • Integration of hard and soft aspects is key – each covers inherent weaknesses of the other • No organization-wide roll-outs of Six Sigma without training senior managers how to support it – top management dialogue can’t stop after the approval and initial re-organization into teams. • Resist the temptation to use good -- not great -- performers as driving change agents, such as Black Belts. • Go for lean manufacturing techniques before Six Sigma to demonstrate quick wins unless data for analysis already exists (as it did for a field service warranty process) • Strive to “over-communicate” and request feedback on the content and quality of communication.

    36 Lessons Learned Implementation • Maintainflexibility in the planning that other options can be considered as you move forward. • You can generally do more than most people think. • Ensure responsibilities are clearly assigned. • Ensure leaders of change are optimistic and will push project through to completion. • Groom the subsequent leaders • The restructuring into teams -- this can not be a pilot. • Executives need to agree on their individual and collective areas of responsibility for business processes. • Design structures and processes that ensure control. • Training for new leaders needs to mandatory, not optional • Bring Finance and HR into the process soon. • Executive efforts can decrease as the transformation progresses if the soft elements of HPO are successfully anchored. • It is extremely important to provide frequent status reports for the improvement projects.

Editor's Notes

  • #6 Both go after the same big goal, but in a different way. Great companies doing process improvement don’t distinguish; they do both.
  • #8 Audience participation: how many people ever been on a great team? What were charactersistics of, what feel like? Ever probls protecting from rest of org to do work? Well HPO is about not needing protectoin because all have team values, practices (not just sense of “teamwork” Dilbert cartoon) So, why fix something that isn’t broken by adding a component (in electrical products this is bad!) Success like GE, AlliedSignal, Honeywell (truth is, they DID) and this is the change management portion-often cited as the most problematic! Most leadership tips over next two days apply to LSS and LSS/HPO
  • #10 Phil Define value added and non-value added. Give examples. Decreasing proportion of non-value added activity will improve efficiency. Give examples of waste (i.e. inventory stops, inefficiencies in material and information flow, etc.) Express inventory in common unit throughout. Unit should be meaningful to your customers. Try to maintain “pull” through system. Inefficiencies in information flow can be as critical as material inefficiencies.
  • #15 A Control Chart is a graphic that monitors an important characteristic of a process over time. A Control Chart is useful for: Answering the first of two key questions about your process: Is the process in control? That is, is it predictable and stable over time? (process control) If the process is in control, then, is it capable of meeting your customer’s requirements? (process capability, see Capability Analysis) The ability to distinguish between the two sources of variation as a guide to taking appropriate management action Common Cause Variation: the natural, inherent variability of the process due to people, methods, materials, equipment, machines, and environment that are used. Common cause variation is present in the system or process at all times; the people working in the system can do nothing about it. Therefore, it is the responsibility of management to change the system or process to improve it. Special Cause Variation: the variability which results from a unique, or special circumstance, usually attributed to one individual or piece of equipment. It is not a normal part of the process. It is the responsibility of the individual working at the point of the process where the special cause occurred to improve it. Upper and Lower Control Limits on a Control Chart, help in determining the source of variation and who has the responsibility for eliminating it. A Control Chart is also useful for: Documenting a team’s effort to effectively change a process. That is: Sets the baseline or current operating level. Show’s the change to the improved operating level. Helping the process perform consistently and predictably to allow the process to achieve higher quality, lower unit cost, and a higher effective capacity.
  • #20 The “DMAIC”Improvement Process DMAIC is the Six Sigma problem-solving process teams use. It stands for Define-Measure-Analyze-Improve-Control. (It is pronounced duh-MAY-ick.) By methodically following this simple, but highly effective five step process, teams can make significant process improvements. DMAIC is useful for: Helping teams design solutions that are sustainable once implemented Providing a framework for when tools should be used Providing a sequence of optimal tool usage and linkages among tools. Helping practitioners understand how the tools and improvement phases are related, and how the tools support each other to produce an output that can be acted upon. It is essential that leaders understand the high level steps of the DMAIC improvement process. In project status meetings leaders should require that teams state which DMAIC phase they are in to provide a context for productive discussion. This provides a common ground for discussion, a context for applying lessons learned from previous similar steps, and a useful context for applying step-specific questions to the discussion of process improvements.

  • #31 There are seven hallmarks of the discipline of LSS: Statistical methods. Methods that collect and analyze data are an important part of reducing variation in processes. Attention to workplace and tool organization. A set of mindsets, practices, and discipline that keeps work areas clean and uncluttered with tools and materials, and instead sorts and neatly arranges these items for easy retrieval and use. Fanatical focus on the external customer. One key element that distinguishes LSS from earlier Total Quality efforts is the high amount of attention paid to meeting external customer requirements and expectations. Senior managers as well as team members alike constantly ask, “How will what we’re doing here affect the external customer?” Attention to process. A process is a set of activities and decisions that collectively produce an output for an internal or an external customer. Often these processes span departmental boundaries, and improving these tend to have the highest likelihood of producing significant financial gain. Processes are the heart of “where the action is” with LSS. Pre-screening, and ongoing screening of improvement projects to ensure fit with strategy and financial return. Another important departure from traditional quality efforts is LSS’s initial, and ongoing requirement that projects must support strategy and yield a targeted financial return. This hallmark is true at the start of, and throughout the project. People strive for perfection, but noble mistakes are tolerated. While 3.4 parts per million is near perfection, along the way people must feel safe to make a mistake. If they don’t, then it is unlikely they will try anything really different that could yield significant gains. Obviously, certain types of mistakes – e.g., repeated mistakes and lack of follow-through -- can not be tolerated, but other types of mistakes should be considered potential learning opportunities. An analysis-rich and measurement-rich environment. LSS environments collect lots of data and project participants perform numerous data analyses – far more than typical organizations without LSS. In addition, in LSS companies, measurement is something that happens everywhere. A classification and sorting process to determine the type of tools to apply. Some problems are simple, while others are complex. Organizations need to develop internal rules that specify when a problem would benefit from simple tools like process maps and the application of streamlining principles, and when a problem would require more extensive data collection and statistical analyses.
