…yah but how will Lean Six Sigma do that for me???
• It is a problem solving methodology to put recurring problems to bed!
• It will facilitates communication between people with different backgrounds and from
different functions
• Allows you to leverage and build on what you already know!
• Can be applied in all areas of your life and career
• It is built on standard tools and a standard methodology – helps simplify your
discussions!
• Helps drive focus and prevents gaps in logic
• Uses data for sound conclusions
• Focuses on fundamentally solving a problem NOT on adding band-aids and
additional complexity
• Requires team involvement and emphasizes sound communication
• Minimizes emotion and conflict and moves to data-driven process-based solutions
• It is visible to higher levels of the company
• It has been proven successful across many industries, solved countless problems
and saved billions of dollars

Trang 7Sigma
Origins of Lean
• Lean has been around a long time:
• Pioneered by Ford in the early 1900’s (33 hrs from iron ore to finished Model T,
almost zero inventory but also zero flexibility!)
• Perfected by Toyota post WWII (multiple models/colours/options, rapid setups,
Kanban, mistake-proofing, almost zero inventory with maximum flexibility!)
• Known by many names:
• Toyota Production System
• Just-In-Time (JIT)
• Continuous Flow
• Outwardly focused on being flexible to meet customer
demand, inwardly focused on reducing/eliminating the
waste and cost in all processes
• Highly applicable to transactional businesses!
• Whenever flexibility and speed are key: banks, technology firms and customer

The Mathematical Foundation for
Lean is Little’s Law
• To reduce Lead time, you have 2 choices:
• Invest dollars of capital in people and equipment to increase Avg
Completion Rate
• Invest Intellectual capital to reduce number of “Things In Process” using
Lean Tools (Pull Systems, Setup Reduction, etc) and Six Sigma tools
(Variation Reduction)
• Little’s Law: Mathematics of Theory of Constraints (TOC) and
Toyota Production System (TPS)

Sources of Waste
1 Transportation (moving items from one place to another)
2 Inventory (items/paperwork/information waiting to be processed)
3 Motion (excess movement and/or poor ergonomics)
4 Waiting (delays caused by shortages, approvals, downtime)
5 Overproduction (producing more than is needed)
6 Overprocessing (adding more “value” than the customer is paying
for)
7 Defects (rework, scrap, inspection – Costs of poor quality)
Another waste is: People (untapped and/or misused resources)

Toyota Production System – Waste
Elimination (Applies to Every Process)
“The ability to eliminate waste is developed by
giving up the belief that there is ‘no other way’
to perform a given task It is useless to say, ‘It
has to be done that way,’ or ‘This can’t be
Trang 11Sigma
Lean Defined
• An enabler to business strategy
• A way to remove waste from processes and practices
• Focused on process speed and flexibility
• Driven by quick-hit, high-impact team events to solve
problems
• A way to visualize processes through value-stream mapping
• A way to teach people how to “think” about streamlining
• A business strategy
• Only for manufacturing companies
• About headcount reductions
• Only about the tools
Trang 12Lean Six Sigma
But Lean Alone Has Holes
• Top leadership engagement
• Deployment organization (Champions, Black Belts, etc.)
• Sometimes lacks focus on customer
simply “account for” the variability by carrying excess
inventory and resources
process under statistical control and maintaining that
control allowing for unpleasant surprises

Six Sigma History
• Motorola was the first advocate in the 80’s
• Six Sigma Black Belt methodology began in late 80’s/early 90’s
• More recently, other companies have embraced Six Sigma:
• Top-down program with Executive and Champion support
• Outwardly focused on Voice of the Customer, inwardly focused on using
statistical tools on projects that yield high return on investment
Trang 15Sigma
Six Sigma History
• Nobody at GE gets promoted without Six Sigma training
• GE annual report examples:
• 10-fold increase in life of CT scanner x-ray tubes
• Improved yields of super-abrasives – worth a full decade of
increased capacity despite growing demands
• 62% reduction in turn-around time of railcar leasing repairs
• Plastics business added 300 million pounds of new capacity –
equivalent to “one free plant”

Why 99% Is Not Good Enough
• 20,000 lost articles of mail per hour
• 5,000 incorrect surgical operations per week
• 200,000 wrong drug prescriptions each year
• No electricity for almost 7 hours per month
Trang 18Lean Six Sigma
Six Sigma Defined
• What Six Sigma Is:
• An enabler to business strategy
• Places customers at the center of performance improvements
• Fact-based approach for improving business processes and solving business
problems
• A proven methodology and toolset supported by deep training and mentoring
• Focused on reducing variability of processes
• A way to develop highly skilled business leaders
• A means for creating capacity in organizations
• What Six Sigma Is Not:
• A business strategy
• A way to develop statisticians and engineers
• Only for manufacturing companies
• Only about “cost reductions”
• A “flavor of the month” approach
Trang 19Sigma
But Six Sigma Alone Has Holes
• Six Sigma lacks many concepts and tools lean is strong in
• Work in process control and reduction
• Six Sigma has long time-lines for projects (4-18 months)
compared to Lean (1-4 months)
• Six Sigma specialists (Black Belts) are often less productive than Lean specialists
• Six Sigma Black Belts do 3-5 projects a year
• Dedicated Lean project leaders do 10-20 projects a year
• Six Sigma is often seen as being “too slow”
Trang 20Lean Six Sigma Lean and Six Sigma Integration
Trang 21Sigma
Why Integrate?
“We knew we wanted to have Six Sigma Tools, that was clear But we also decided that what really makes change in a factory are some of the Lean tools Putting in a pull system, reducing batch sizes, significantly changing setup times, all of a sudden
everything starts to flow
Those are the types of things we saw over time that really
made a difference in our factories and so we said that has to
be a part of this training.”
– Lou Guiliano, ITT Industries CEO
on integrating lean techniques into ITT’s Six Sigma Rollout

Integrating Lean and
Six Sigma Initiatives
• Lean and Six Sigma can co-exist independently,
but the benefits of integration are tremendous
• Single channel for employing limited resources
• One improvement strategy for the organization
• Highly productive and profitable synergy
…while the pitfalls of not integrating them are
formidable
• Divided focus of the organization
• Separate and unequal messages for improvement
• Destructive competition for resources and projects
