Foundation to Lean 6 Sigma

• Definitions of Insanity:– Doing the same thing over and over and expecting

a different outcome!• AND– Using the same logic to get out of the trouble that

got you there in the first place!

Albert Einstein

Lean 6σ

• "To measure is to know.“• "If you can not measure it, you can not improve it.“• "…I often say that when you can measure what you

are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind ”

Lord Kelvin

Right Training. Right Attitude

• Lean Six Sigma is not rocket science…you can do this• Lean Six Sigma is not “easy”…it requires dedication

and effort• Lean Six Sigma is not the next program…it is a way of

thinking…an approach to every task performed, that asks the question…“does this add value?”

Lean 6σ

What is Lean?

• Identifying improvement opportunities in processes• Utilizes scientific problem solving methods• Focus on reducing non-value added steps in a

process• Analyzing and improving process flows• Reducing complexity• Solving many smaller problems

The Lean LadderLean 6σ

Page 11: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

Eight Types of Waste

• Wastes-Those Elements of a process that Do Not Increase the Value of a Product or Service as perceived by the Customer, but Increases Cost and Cycle times.– IDENTIFY AND ELIMINATE THESE WASTES:

• Types of Waste:– T Transportation– I Inventory (Excess)– M Motion– W Waiting– O Over-producing– O Over-processing– D Defects– U Under utilization of employees

Why Use Sigma As a Metric? Lean 6σ

Page 16: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

Six Sigma Defined

Six Sigma: • Is a systematic methodology utilizing effective data analysis

tools and techniques to improve performance by eliminating / preventing defects and inefficiencies’ in processes, to meet and exceed customer needs.

• Derives from a 99.99966% error free quality level OR less than 3.4 errors per million opportunities

Integrating Lean and Six Sigma

• Natural evolution• Applies the right tools to a project• Leverages tools and methodologies to

maximize process improvements• Reducing waste and variability go hand in

hand in process improvement

Lean 6σ

Page 19: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

What Lean Six Sigma is not

• A complicated way to manage your organization• Anew way for the “Quality Department” to audit

reports and performance• Something that requires you to discard what you

learned with TQM, CQI, etc.• A new way to spend money without clear benefit to

the organization• Something that requires a complicated computer

system• A way to eliminate jobs

Lean 6σ

History of Lean, Six Sigma

• Frederick W. Taylor: 1880s-early 1900s, systematic study of workers’ use of time and motion

• Henry Ford: continuous flow production, waste elimination• TWI: (Training Within Industry), 1940-1945• W.E. Deming and Joseph Juran: took quality control to Japan in 1953• Kiichiro Toyoda and Taiichi Ohno: low inventories, flexibility• U.S. supermarkets: pull systems• Shigeo Shingo: mistake proofing, reduced set up times• Toyota Production System NIKE• MIT and James Womack: bring Lean back to U.S.• NBC White Paper: If Japan can, Why can’t we?, 1980s• Eli Goldratt: published book The Goal”, early 1980’s• Motorola: global deployment launched Six Sigma 1987, opportunity for error

VersatilityLean 6σ

Page 23: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

When to Use the LSS Process

• When to Use:– Driven by the Business Strategy– Problems that “have been around as long as we can remember.”– Solution is not known or is not obvious– You are willing to commit people to identify and resolve the issue– You want a more definitive solution than traditional methods can provide– You want to encourage the upward flow of ideas and build team spirit– You want group ownership of a course of action

• When NOT to Use:– You don’t have a specific challenge or clear issue to solve– You already have a solution and course of action– You don’t have a consistent process to improve

Lean 6σ

Page 24: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

Lean Six Sigma Principles

• Identify value in the eyes of the Customer– Learn to see your processes from the perspective of

your customer• Identify the value stream and eliminate waste/variation• Make value flow at the pull of the customer• Involve, align, and empower employees– Develop solutions using the people who are currently

working in the process• Continuously improve knowledge in pursuit of perfection

Lean 6σ

Page 25: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

Continuous Improvement

• A framework for constantly improving organizational performance

• Provides steady, incremental improvement in everything we do to meet/exceed changing expectations:– Better quality– Faster turnaround– Lower costs– More responsive service

• A relentless, never-ending process• Requires that we all change the way we think talk work

think, talk, work, and act

A Program of Process Improvement

Continuous Process Improvement (CPI) is a deliberate change in Process Performance

Lean 6σ

Page 27: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

The Importance of Reducing Variation

• To increase a process Sigma Level, you have to decrease the variation

• Less variation provides:– Greater predictability in the process– Less waste and rework, which lowers cost– Products and services that perform better and last

longer– Happier customers

Foundation to Six Sigma

Y = f(X)Y is: Xs are:

Output Inputs

Dependent Independent

Observed Controlled

Effect Causes

Result Reason

Lean 6σ

Page 29: Lean Six Sigma Department of Defense Lean Six Sigma Executive level overview.

Identify and control the X’s

• Y = f(X1,X2,…)• In Improvement

– Identify the key X’s to reduce variation in the Y• In Design

– Carefully set specifications on the X’s so that we get the desired Y

• In Process Management– Monitor and control the X’s to assure we will get the desired Y

Process output is A function of Key process and input factors that cause variation in the output
