A Management driven, scientific methodology for
product and process improvement which creates
breakthroughs in financial performance and
Customer satisfaction
7What is Six-Sigma?
- Management mandated and directed improvement
program focused on breakthroughs in financial
performance and customer satisfaction - Uses Champions, Black Belts and Green Belts to
facilitate change - Focused on core business and Customer needs
- A systematic method for process and product
improvement - A Greek symbol for measuring performance
variation - A metric for evaluating performance quality
- A standard of excellence (3.4 defects per million
opportunities)
8Customer Satisfaction Efficient Systems
Improved Profitability
- Two types of projects to improve financial
performance - Increase Revenue Grow the Business
- Improve Customer satisfaction, sales, capacity
and market position - Decrease the Cost of Goods Sold
- Reduce variation and defects
- Improve yields
- Understand root cause of issues and eliminate
the source of problems - Automate process workflow
- Improve process performance and reduce waste
using lean principles

manufacturability, Customer satisfaction and cost
reduction within all components of the
development and new product introduction process.
Focused on operational excellence, Customer
satisfaction and cost reduction within all
components of the operation. Areas of focus
include Sales, HR, Finance, Materials,
etc. Focused on product production excellence,
variation and defect reduction, lean production
techniques, Customer satisfaction and cost
reduction within all components of the production
and delivery process.
Six Sigma touches on all aspects of the Business
Enterprise
12Past Improvement Activity Failure Modes
Unsuccessful Projects No clear Management mandate
No roadmap for the project
not sure where we are going No dedicated
resources No Management and performance review No
ability to measure performance and examine
effectiveness not sure if we accomplished
anything No financial ROI during project
definition and measurement at completion No clear
answer as to why are we doing this project?
13What Makes Six Sigma Work?
- Select and work on the most important problems
and projects to the business and Customer - Assure those projects impact customer
satisfaction and financial performance - Allocate the time to get the work done
- Have your best people work on them
- Provide those individuals with all the training,
tools, and resources they need to make the
performance breakthrough - Provide Management direction, support and routine
review of performance - Require a well thought out, objective and data
driven solution - Verify the dollar savings of your efforts
- Sustain the benefits of the solution over time
14Six Sigma 3 Critical Elements
Defining and using business objectives and
metrics that focus our attention on performance
and defects that are most important to the
customer and have the greatest potential for
impacting the bottom line
Dedicated resources and focused infrastructure,
trained in the use of the 6 Sigma problem solving
and process improvement methodology
Systematic Approach to improving performance and
reducing defects which are important to the
customer (qualitative statistical)
15Strategic Business and Quality Metrics
CSI, Sales, delivery times, cost per unit, Yield,
DPU, DPMO, customer response times, Web hit
rates, Rework/scrap rates, etc.
(Critical Business Elements)
Management objectives and dashboard forms the
core of the strategic Business Quality Metrics
and is flowed down to other departments and
process areas to provide leading and lagging
indicators of performance

20Honeywell DOW Results
"We achieved 600 million in Six Sigma cost
savings in 1999, but cost savings are only one
part of the story. Delighting customers and
accelerating growth completes the picture. When
we are more efficient and improve work flow
throughout every function in the company, we
provide tremendous added value to our
customersthrough higher quality solutions that
are more competitively priced, delivered on time
and invoiced correctly. That makes us a more
desirable business partner." - Honeywell 1999

38Detailed Project Selection Criteria
DMAIC Methodology Define
- Achieving breakthroughs requires prioritization
of opportunities. There are many more
opportunities than there is time and resources to
work on them. - When selecting a process, we are trying to
prioritize exactly which problem to solve. If
the problem is clear we move on to define the
problem. - In selecting a project, consider these issues
- Financial and strategic benefits
- Improved customer satisfaction, CSI
- Compatible with current goals and objectives
- Translatable to other areas of the business
- Probability of success
- Level of effort, amount of resources needed to
complete project
39Example Prioritizing Projects
DMAIC Methodology Define
Are your projects the things you like to do, easy
to do or important to do?
40Develop Charter
DMAIC Methodology Define
In this step you will establish direction for
the project by documenting
- Problem
- Objective Scope
- Goal/target
- Resource requirements
- Financial benefits
- Strategic benefits
- Team resources
- Project approval
41 Develop Charter Problem Statement
DMAIC Methodology Define
A clear description of the problem to communicate
to other people in the process and rally support
to improve it
- A description of the issue or problem
- What, when, where and how the problem occurs
- What is critical to quality (CTQ) from the
customer perspective? What is nonconforming to
specifications? - Define the boundaries of the problem, how big is
the problem? - What are the consequences of the problem to the
Company and or Customer? - Do not state a solution when describing a problem
Description of the Pain
42State Objective and Scope
DMAIC Methodology Define
Project Objective and Scope
- What process will the team focus on?
- What are the boundaries of the process we are to
improve? Where does the
process begin? Where does it end? - Which customers will be affected / included
- What is outside of scope for the team?
- What constraints or timelines must the team work
under?
Customer or Suppliers Site or
Line Process
Process 1 Process 2 Process 3
43Goal Statement
DMAIC Methodology Define
- Describe, in measurable terms, what success will
look like when youve solved the problem - Include a statement of the performance level that
will satisfy your CTQ and the time frame in which
you plan to implement the improvement. State
targets and tolerances where appropriate.
Goal Statement Reduce late shipment costs
(Express Mail) to all customers by 70 from 1.5M
to 45K by January 200x. Where

44Determine Resources
DMAIC Methodology Define
Determine the Stakeholders Who will need to be
involved and at what level for this project to be
successful? Determine Team Members Who will need
to be on the team and at what of their
time? Determine any Capital, Test or HR
Requirements What materials, testing, software
programming, outside services or equipment will
be needed? Are those costs acceptable to
management? Other Support to be Successful

DMAIC Methodology Define
Project plan remains through the life of the
project
46Benefits
DMAIC Methodology Define
- Benefits may include any of the following
- Hard dollar savings (cost reduction)
- Soft dollar savings (cost avoidance)
- Improved Customer satisfaction
- Improvement in the performance metrics (cycle
time, yield, defects, etc.) - Improved job satisfaction (reduction in
frustration) - When considering benefits what must change for
the savings to occur?

51Begin Management/Champion Reviews
DMAIC Methodology Define
Once the project charter has been approved and
the team formed around the project it is
essential to begin periodic management reviews of
project performance. Black Belts and Green
Belts meet with Management to report
performance. Champions report to executive staff
on project performance. Where possible integrate
reviews into current management forums.

Elements for a data collection plan
Data means nothing without an understanding of
what the data is, how it was collected, and the
conditions under which it was measured Data
properly collected and analyzed will help us to
understand the root cause(s) of the problem
58Collect Visual Data to See the Problem
DMAIC Methodology Measure
Where possible use a Digital or Video Camera and
capture the defect or process problem. A
picture is worth a thousand words in
understanding and communication of the origin and
nature of problems.

62Benchmarking
DMAIC Methodology Analyze
No company is the best at all it does. Typically
there are some core competencies that make a
company great. There is much to be learned by
benchmarking other companies who are the best at
what they do. Benchmarking begins with
identification of the process or business area we
wish to examine. This should be clear from our
problem statement and objective. Knowledge that
there are other ways of doing things can be
obtained from benchmarking. Benchmarking often
speeds up the solution generation process.
63Root Cause Analogy
DMAIC Methodology Analyze
Like pulling weeds unless we address the root
that causes the problem, poor results will keep
coming back. Addressing the results or symptoms
of a problem will never provide lasting solutions
- given a little time the problem will come
back We need to understand the Root Cause of the
problem from our problem statement

70Check List for Root Cause Determination
DMAIC Methodology Analyze
Check and investigate all those that apply to the
problem under consideration
- Measurement
- Poor repeatability
- Poor reproducibility
- Poor accuracy
- Poor stability
- Poor linearity
- Invalid measurement or test method
- Excessive test or measurement
- Methods
- Incorrect definition
- Incorrect sequence
- Missing definitions, implicit rules

- Incorrect information
- Excessive queues or out-time
- Handling
- Orientation
- Materials
- Defective
- Off-specification

715 Whys Example
DMAIC Methodology Analyze
State the problem, then ask why did this problem
occur until you reach root cause.
Missing Parts on the Board During NPI
WHAT? Why? Why? Why? Why? Why?
Improper cassette loading Missing cassette
Machine Malfunction
Failed to locate cassette Part not
available
Supplier problem Order incorrect Lack of
lead time
Design change Customer schedule
Design error Performance improvement
72Root Cause(s) Determination
DMAIC Methodology Analyze
- Root Cause is achieved when we have identified
the source of the problem (use the 5 Why
approach) - For any problem there are typically many Roots.
They vary in frequency of occurrence. We need to
know each root and their associated frequency and
or of impact. - Proper Root Cause identification requires some
explanation of the failure mechanism based on
understanding the process, the physics, mechanics
or chemistry. We must be able to explain how
changes in X cause changes in Y (otherwise we
dont understand it!) - Root Cause is verified when we can recreate or
manipulate the problem - To fix the Root Cause it must be controllable
- Knowing Root Cause does not assure we know the
solution to the problem. Solutions can be
formulated once we know the root of the problem
73List of Potential Root Causes
DMAIC Methodology Analyze
Final investigation needs to be made to determine
if the factors identified are actually the root
cause of the problem
74Summarize All Root Cause Analysis
DMAIC Methodology Analyze
For each possible root cause, determine those you
will verify. Summarize each possible root cause
with the following codes
Non Contributor (NC) Does not contribute to the
problem Possible Contributor (PC) A factor
which may have an effect on the response
Insufficient Data (ID) Not enough data to
determine the effect of the factor (may require
additional effort) Data not available (IDX) Data
not available concerning the factor Root Cause
(RC) Determined to be a root cause of the
problem Non Controllable Root Cause (RCX) A root
cause however, outside the control of the
company, individual or team
75Root Cause(s) Validation and Summary
DMAIC Methodology Analyze
- List all probable Root Cause(s)
- Rank them in terms of effect size
- Determine the additional tests and or
manipulation you plan to use to validate the
factors (X) which have the greatest effect on the
response (Y) - Identify potential methods for controlling the
factors which create the problem - When validation is complete summarize all
selected Root Cause(s) and their effect size

79Brainstorm Potential Solutions
DMAIC Methodology Improve
- Use general brainstorming techniques to generate
process and design change ideas which will
eliminate the root cause of the problem. - Separate ideas into short term and long term.
Long term with take 3 months or more to
implement, short term is less than 3 months. - Use voting and management involvement to generate
consensus on direction of approach - A single solution is not required at this point
in the improvement process. 2 - 3 short term
solutions should be selected and ranked. 1 to 2
long term solutions should also be selected for
evaluation and experimentation.
80Consider Solutions That Remove Process Waste
DMAIC Methodology Improve
Seven muda 1. Over production ahead of
demand 2. Waiting for the next process step or
information 3. Transporting materials
unnecessarily 4. Over processing 5. Inventory
that is more than bare minimum 6. Motion by
employees that is unnecessarily 7. Producing
non-conforming parts For each area of waste,
examine each process step to determine if waste
occurs in the operation and how to remove the
waste from the production system

DMAIC Methodology Improve
Design experiments which improve the robustness
of the process. Improve process parameter
design, tolerance design and reduce the source of
defects.
Once experiments are complete critical process
parameter sensitivities can be modeled and
determined how to be targeted and controlled.
84Evaluate Cost, Complexity, Impact,Benefit and
Risk for Each Solution
DMAIC Methodology Improve
- Assure solution costs and timelines are
acceptable to management - Determine the complexity of each solution in
terms of time and ease of completion - Identify potential impact (change to the
baseline) of each solution. Explain how each
solution will address the root cause and impact
real change in performance. - Financial benefit benefit of solution cost to
implement - Assess the risks associated with each solution
and the likelihood of occurrence - Determine need to involve/notify customer
concerning any product or process changes - Make sure that proper validation occurs
associated with the solution prior to across the
board implementation
85Solution Evaluation Form
DMAIC Methodology Improve
Evaluate solution alternatives to assure the best
solution has been selected
86Evaluating Risk
DMAIC Methodology Improve
Evaluate failure modes and probability to
minimize any negative effects of changes to the
product or process
87Involve the Champion, Discuss with Management
DMAIC Methodology Improve
Once the team has completed their work it is now
time to review solutions with Management. Allow
the team to benefit from a fresh perspective and

92Process Controls
DMAIC Methodology Control
- TYPES of CONTROLS
- Measurement Based Control Test Inspection
- Management Dashboards Review Test (error
prone) - Statistical Process Control Inspection (poor
effectiveness and costly) - Documentation Periodic Checks
- Process Flow Diagrams Scheduled Maintenance
- Product Drawings, Schematics Scheduled
Calibration - Process Management Plans Training and Operator
Certification - Written Procedures Audits
- Training Periodic Management Reviews
- Design Incentives
- Design out Product Problems Measures which are
associated with a bonus - Mistake Proofing Measures which are
associated with a penalty - Robust Design Concepts
93Elements of a Control System
DMAIC Methodology Control
Sensor (measurement technology control
chart) Allows the system to monitor the current
process performance Alarm (control limits and
trend rules) Establish limit(s) and run rules
which require attention Control Logic (OCAP) A
predefined set of actions to follow that are
alarm specific Validate (next sample) Assure the
action was effective
Add alarms where needed and assure we do not
ignore valid alarms. SPC methods should be used
to establish alarms.
94Define Sustaining Requirements
DMAIC Methodology Control
What Vacuum will be created when you leave?
- Now that the solution is known and you are ready
to finish the project. - Determine the activities that need to continue
after the team is dissolved - Define who is doing them now who should be the
long term owner? - Determine who needs to do them in a sustaining
long term mode - Define the set of tasks or systems that must be
installed prior to completing the project and
backing out of the work - What else will be needed to make the solution
effective and sustainable? - From the above issues, develop a transfer plan
95Realize the Benefits of Improvement
DMAIC Methodology Control
How did you justify the cost savings for the
project? What changes will have to occur to
create the savings? Based on the impact of the
benefits of the solution have you made changes to
the process to realize the benefits? Possible
Actions Re-deploy personnel Reorganize the
floor Reduce inventory levels in Planning
System Eliminate inspection or test
operations Modify Vendor/Customer contracts Other
cost saving changes to the operation
96Close the Project or Improvement Team
DMAIC Methodology Control
- The goals have been met and the team has been
successful - The solutions have all been implemented and
demonstrated to be effective - Assure all documentation is complete
- Determine what standardization opportunities are
available - Make sure the accomplishments of the individual
or team are appropriately recognized personally
and publicly - Measure and communicate results of the project
(benefits and savings) - Celebrate! We did it!
