Design for Lean Six Sigma (DFLSS)

A design process for re-engineering opportunities
(DMADV)




Objective is to design a new process with Six Sigma quality
to start
Focus is on “front-loading the pain”
Must be identified by management as major
opportunities for savings and/or customer satisfaction
Projects will be longer; team members may need to
be back-filled in their jobs for the duration of the
project
Tools: QFD, Benchmarking, FMEA, DOE, Simulation, Optimization, Life-Cycle
Planning, Taguchi Loss Functions, and TRIZ

Design for Lean Six Sigma (Continued)
DFLSS Dimensions:
 Design for Manufacture and Assembly
 Design for Reliability
 Design for Maintainability
 Design for Serviceability
 Design for Environmentality
 Design for Life-Cycle Cost
Benefits Include:
 Reduced Life-Cycle Cost
 Improved Quality
 Increased Efficiency and Productivity
“When organizations are considering making a change, they will consider associated
costs, but will not give adequate consideration to the cost of not making the change.”
Source: F. Breyfogle, Implementing Six Sigma, 2003
DFLSS Tools: Life Cycle Planning

The probability of a new product or service
failure is highest in the early stages due to
design or production flaws, and decreases and
then levels out with usage




e.g., initial problems with new cars or homes
However, at some point, the probability of
failure increases as parts wear out
Some systems are repairable or replaceable,
while others are not
DFLSS planning must consider these factors
DFLSS Tools: Life Cycle Planning
Bathtub Curve
Don’t Waste Money on Extended Warranties!
Many stores recommend the purchase of extended warranties to go with
consumer electronics. They are available for automobiles as well, but they are
rarely if ever cost effective. The bathtub curve (a model for failure or hazard rates
in reliability engineering,) explains why.
How does this curve suggest the best way to prioritize defect reduction?
DFLSS Tools: Simulation

A method for replicating real world relationships
with the aid of a computer

Utilizes historical data and
other knowledge

Allows for the study of variation
in processes

Enables analysis without disrupting the real
system

Not an optimization technique - decision
variables are inputs to a simulation
DFLSS Tools: Design of Experiments
DOE is a statistical procedure for
conducting a controlled
experiment, where the impact of
high versus low settings of X’s are
determined, including possible
interactions
Examples:
 Vary the time and temperature
and amount of butter used to
bake a batch of cookies.

Vary elements of a website to
measure the impact on customer
click-through or purchase rates
DFLSS Tools: Theory of Inventive
Problem Solving (TRIZ)



A combination of methods, tools, and a way of thinking
developed in the Soviet Union in the 1940s
Used for concept generation and problem-solving
Assumes that all inventions contain at least one
contradiction



e.g., faster auto acceleration reduces fuel efficiency, productivity
vs. accuracy, etc.
Success depends on resolution of contradiction
Involves trade-off between contradictory factors, or
overcoming the contradiction


Despite the immensity of problems, only 1250 typical system
contradictions in 39 design parameters have been found to date
Many Triz tools have been developed to deal with these
contradictions

Lean and Single Supplier Strategy
Advantages
 Reduction in variability
 Time saved dealing with many suppliers
 Volume discount from single supplier
 Minimized identification issues when field failures
 Priority access to supplier’s R&D breakthroughs
Disadvantages
 Fewer brainstorming and competitive benchmarking
opportunities
 Dependence on one supplier to get it right
 Potential loss of diversity of suppliers
Other Lean Considerations


Many organizational decisions negatively
impact continuous flow
Lean continuous flow is not always appropriate



Multiple supplier relationships cannot support
Lean



Innovative products
Need responsiveness and flexibility
Single supplier strategy is needed,
even for critical resources
Need to partner with a supplier to
achieve your Lean goals!
