4Six Sigma Methodologies
- Six Sigma methodology is a proven tool set for
driving and achieving transformational change
within an organization. It is a business
improvement process that focuses an organization
on customer requirements, process alignment,
analytical rigor, and timely execution. - Six Sigma is a measure of quality that strives
for near perfection. The Six Sigma process uses
data and rigorous statistical analysis to
identify "defects" in a process or product by
reducing variability and achieve as close to zero
defects as possible.
- The DMAIC methodology breaks down as follows
- Define the project goals and customer (internal
and external) requirements. - Measure the process to determine current
performance. - Analyze and determine the root cause(s) of the
defects. - Improve the process by eliminating defect root
causes. - Control future process performance.
- DFSS is the acronym for Design For Six Sigma
- The five phases of DMADV are defined as
- Define the project goals and customer (internal
and external) requirements. - Measure and determine customer needs and
specifications benchmark competitors and
industry. - Analyze the process options to meet the customer
needs. - Design (detailed) the process to meet the
customer needs. - Verify the design performance and ability to meet
customer needs.
- DCCDI methodology breaks down as follows
- Define the project goals.
- Customer analysis is completed.
- Concept ideas are developed, reviewed and
selected. - Design is performed to meet the customer and
business specifications. - Implementation is completed to develop and
commercialize the product/service. - DMEDI is being taught by PricewaterhouseCoopers
and stands for Define, Measure, Explore, Develop
and Implement.
- IDOV is a well known design methodology,
especially in the manufacturing world. - Identify the customer and specifications
(Critical To Quality CTQs ). - Design translates the customer CTQs into
functional requirements and into solution
alternatives. A selection process whittles down
the list of solutions to the "best" solution. - Optimize uses advanced statistical tools and
modeling to predict and optimize the design and
performance. - Validate makes sure that the design you've
developed will meet the customer CTQs.

7KAIZEN
- The Japanese word "KAIZEN" means improvement,
improvements without spending much money,
involving everyone from managers to workers, and
using much common sense. The Japanese way
encourages small improvements day after day,
continuously. The key aspect of KAIZEN is that it
is an on-going, never-ending improvement process.
It's a soft and gradual method opposed to more
usual western habits to scrap everything and
start with new. - Kaizen activities can be conducted in several
ways. First and most common is to change worker's
operations to make his/her job more productive,
less tiring, more efficient or safer. To get
worker buy-in as well as significant improvement,
worker is invited to cooperate, to reengineer by
himself and with help of team mates. The second
way is to improve equipment, like installing
foolproof devices (poke yoke) and/or changing the
machine layout. Third way is to improve
procedures. All these alternatives can be
combined in a broad improvement plan. - The first stage is reviewing the current work
standards to check the current performance and
than estimate how and how much performance can
still be improved. When new leap is done, upgrade
the standards. - Kaizen is controlled It is not acceptable to let
anybody change designs, layouts or standards for
some pretended "improvement". Most often Kaizen
is controlled by improvement groups and
everybody, regardless to rank or position, is
encouraged to suggest through suggestion
submitting system (TEIAN in Japanese).
Suggestions will be discussed by authoritative
committee. Suggestions likely to be turned into
application are usually rewarded according to the
global gain. Improvement idea can be a response
to a problem exposed by KAIZEN committee or come
out spontaneously.
8Lean Production
- Lean production is aimed at the elimination of
waste in every area of production including
customer relations, product design, supplier
networks and factory management. Its goal is to
incorporate less human effort, less inventory,
less time to develop products, and less space to
become highly responsive to customer demand while
producing top quality products in the most
efficient and economical manner possible. - Seven types of waste
- Overproduction to produce more than demanded or
produce it before it is needed (JIT). It is
visible as storage of material. It is the result
of producing to speculative demand - Inventory or Work In Process (WIP) is material
between operations due to large lot production or
processes with long cycle times (kanban) - Transportation does not add any value to the
product. Instead of improving the transportation,
it should be minimized or eliminated (e.g.
forming cells) - Processing waste should be minimized by asking
why a specific processing step is needed and why
a specific product is produced. All unnecessary
processing steps should be eliminated - Motion of the workers, machines, and transport
(e.g. due to the inappropriate location of tools
and parts) is waste. Instead of automating wasted
motion, the operation itself should be improved - Waiting for a machine to process should be
eliminated. The principle is to maximize the
utilization/efficiency of the worker instead of
maximizing the utilization of the machines - Making defective products is pure waste. Prevent
the occurrence of defects instead of finding and
repairing defects (poke yoke). - Muda Any wasteful activity or any obstruction
to smooth flow of an activity. Activity Work
Muda - Mura Inconsistencies in the system
- Muri Physical Strain
9TQM
- Understand customer needs. Develop processes that
continuously collect, analyze, and act on
customer information. Activities are often
extended to understanding competitor's customers.
Developing an intimate understanding of customer
needs allows TQM organizations to predict future
customer behavior. - Integrate customer knowledge with other
information and use the planning process to
orchestrate action throughout the organization to
manage day to day activities and achieve future
goals. Plans are reviewed at periodic intervals
and adjusted as necessary. The planning process
is the glue that holds together all TQM activity.
- Understand that customers will only be satisfied
if they consistently receive products and
services that meet their needs, are delivered
when expected, and are priced for value. Use the
techniques of process management to develop
cost-controlled processes that are stable and
capable of meeting customer expectations. - Understand that exceptional performance today may
be unacceptable performance in the future so use
the concepts of process improvement to achieve
both breakthrough gains and incremental
continuous improvement. Process improvement is
even applied to the TQM system itself! - The final element of the TQM model is total
participation. Understand that all work is
performed through people. This begins with
leadership. Top management must take personal
responsibility for implementing, nurturing, and
refining all TQM activities. They make sure
people are properly trained, capable, and
actively participate in achieving organizational
success. Management and employees work together
to create an empowered environment where people
are valued.
All of the TQM model's elements work together to
achieve results.
10When all of its elements are implemented
properly, TQM is like a well-built house. It's
solid, strong, and cohesive. If TQM is not
planned for and implemented correctly, it will be
structurally weak and will probably fail.
11Hoshin
- The hoshin process is, first of all, a systematic
planning methodology for defining long-range key
entity objectives. These are breakthrough
objectives that typically extend two to five
years with little change. Second, the hoshin
process does not lose sight of the day-to-day
"business fundamental" measures required to run
the business successfully. This two-pronged
approach provides an extended period of time for
the organization to focus its breakthrough effort
while continuously improving key business
processes day to day. - The hoshin methodology provides
- Breakthrough objective focus
- Development of plans that adequately support
the objective - Review of progress of these plans
- Changes to plans as required
- Continuous improvement of key business
processes and - A vehicle for organizational learning.
-
- Hoshin ensures that everyone in the organization
is working toward the same end. The plan is
hierarchical, cascading down through the
organization and to key business-process owners.
Ownership of the supporting strategies is clearly
identified with measures at the appropriate level
or process owner within the organization. - The hoshin process fits under the umbrella
management philosophy of total quality management
(TQM).
12SWOT Analysis
- SWOT is an acronym for Strengths, Weaknesses,
Opportunities, Threats. - Assists in decision making.
- Here are some examples of what a SWOT analysis
can be used to assess - a company (its position in the market, commercial
viability, etc) - a method of sales distribution
- a product or brand
- a business idea
- a strategic option, such as entering a new market
or launching a new product - a opportunity to make an acquisition
- a potential partnership
- changing a supplier
- outsourcing a service, activity or resource
- an investment opportunity
13Balanced Scorecard
- The balanced scorecard forces managers to look at
the business from four important interconnected
perspectives. - Reference The Balanced Scorecard by Kaplan
Norton. IBSN0-87584-651-3 - The balanced scorecard method seems to be more of
a one-way street -- the executive team creates
the strategy, and it cascades down from there. - The balanced scorecard has strong similarities to
Hoshin Planning. Hoshin Planning or hoshin kanri
is widely used by Japanese companies. - One thing that the Japanese emphasize is
"catchball", the process of give and take between
levels/functions/divisions that helps to define
strategy.
Satisfied Employees need effective efficient
Processes to delight the Customers so Financials
will increase thus, increasing Employee
satisfaction Start the flywheel spinning and
people will jump on
-Jim Collins
148 D (8 disciplines)A Process Improvement approach
- 1. Use Team Approach
- Establish a small group of people with the
knowledge, time, authority and skill to solve the
problem and implement corrective actions. The
group must select a team leader. - 2. Describe the Problem
- Describe the problem in measurable terms. Specify
the internal or external customer problem by
describing it in specific terms. - 3. Implement and Verify Short-Term Corrective
Actions - Define and implement those intermediate actions
that will protect the customer from the problem
until permanent corrective action is implemented.
Verify with data the effectiveness of these
actions. - 4. Define end Verify Root Causes
- Identify all potential causes which could explain
why the problem occurred. Test each potential
cause against the problem description and data.
Identify alternative corrective actions to
eliminate root cause. - 5. Verify Corrective Actions
- Confirm that the selected corrective actions will
resolve the problem for the customer and will not
cause undesirable side effects. Define other
actions, if necessary, based on potential
severity of problem. - 6. Implement Permanent Corrective Actions
- Define and implement the permanent corrective
actions needed. Choose on-going controls to
insure the root cause is eliminated. Once in
production, monitor the long-term effects and
implement additional controls as necessary. - 7. Prevent Recurrence
155Ss
- 5S is the Japanese concept for House Keeping.
1.) Sort (Seiri) 2.) Straighten (Seiton) 3.)
Shine (Seiso) 4.) Standardize (Seiketsu) 5.)
Sustain (Shitsuke) - The following are the real meaning of each
element in English Japanese - English
Translations Seiri - Put things in order
(remove what is not needed and keep what is
needed) Seiton - Proper Arrangement (Place
things in such a way that they can be easily
reached whenever they are needed) Seiso - Clean
(Keep things clean and polished no trash or
dirt in the workplace) Seiketsu - Purity
(Maintain cleanliness after cleaning -
perpetual cleaning) Shitsuke Commitment - (Conduct a Gemba Walk where management walks
around the workplace to inspect and ask
non-judgemental productivity questions)
16Good to Greatby Jim Collins (IBSN 0-06-662099-6)
- Level 5 LeadershipLevel 5 leaders channel their
ego needs away from themselves and into a larger
goal of building a great company. Put these
people in leadership roles. - First Who, Then WhatBefore strategizing, get the
right people on the bus. They will be
self-motivated. - Confront the Brutal FactsAcknowledge the
realistic facts of the current status. Confront
reality with open and honest communication. - Hedgehog ConceptDefine what you can be best in
the world at define what you can make money
doing define what your passion is. This is the
Companys long-term Vision. Dont let go of it
Persevere! - Develop a Disciplined CultureAfter the right
people are in place, take planned actions within
the framework of the Hedgehog Concept. Create a
Stop Doing list. - Once people see how improvements and positive
results fit into the Vision (Hedgehog Concept),
they will be motivated to jump on board. This is
called the Flywheel Effect. As momentum of the
flywheel increases, a breakthrough will occur
resulting in Greatness.
17Demings 14 points(reference Out of the
Crisis by W.Edwards Deming IBSN 0-911379-01-0)
- Create constancy of purpose toward improvement of
product and service, with the aim to become
competitive and to stay in business, and to
provide jobs. - Adopt the new philosophy. We are in a new
economic age. Western management must awaken to
the challenge, must learn their responsibilities,
and take on leadership for change. - Cease dependence on inspection to achieve
quality. Eliminate the need for inspection on a
mass basis by building quality into the product
in the first place. - End the practice of awarding business on the
basis of price tag. Instead, minimize total cost.
Move toward a single supplier for any one item,
on a long-term relationship of loyalty and trust.
- Improve constantly and forever the system of
production and service, to improve quality and
productivity, and thus constantly decrease costs.
- Institute training on the job.
- Institute leadership (see Point 12 and Ch. 8).
The aim of supervision should be to help people
and machines and gadgets to do a better job.
Supervision of management is in need of overhaul,
as well as supervision of production workers. - Drive out fear, so that everyone may work
effectively for the company (see Ch. 3). - Break down barriers between departments. People
in research, design, sales, and production must
work as a team, to foresee problems of production
and in use that may be encountered with the
product or service. - Eliminate slogans, exhortations, and targets for
the work force asking for zero defects and new
levels of productivity. Such exhortations only
create adversarial relationships, as the bulk of
the causes of low quality and low productivity
belong to the system and thus lie beyond the
power of the work force. - Eliminate work standards (quotas) on the factory
floor. Substitute leadership. - Eliminate management by objective. Eliminate
management by numbers, numerical goals.
Substitute leadership. - Remove barriers that rob the hourly worker of his
right to pride of workmanship. The responsibility
of supervisors must be changed from sheer numbers
to quality. - Remove barriers that rob people in management and
in engineering of their right to pride of
workmanship. This means, inter alia, abolishment
of the annual or merit rating and of management
by objective (see Ch. 3). - Institute a vigorous program of education and
self-improvement. - Put everybody in the company to work to
accomplish the transformation. The transformation
is everybody's job.
18PDCA cycle
- Plan - a change or a test, aimed at improvement.
- In this phase, analyze what you inted to improve,
looking for areas that hold opportunities for
change. The first step is to choose areas that
offer the most return for the effort you put
in-the biggest bang for your buck. To identify
these areas for change consider using a Flow
chart or Pareto chart . - Do - Carry out the change or test (preferably on
a small scale). - Implement the change you decided on in the plan
phase. - Check or Study - the results. What was learned?
What went wrong? - This is a crucial step in the PDCA cycle. After
you have implemented the change for a short time,
you must determine how well it is working. Is it
really leading to improvement in the way you had
hoped? You must decide on several measures with
which you can monitor the level of improvement.
Run Charts can be helpful with this measurement. - Act - Adopt the change, abandon it, or run
through the cycle again. - After planning a change, implementing and then
monitoring it, you must decide whether it is
worth continuing that particular change. If it
consumed too much of your time, was difficult to
adhere to, or even led to no improvement, you may
consider aborting the change and planning a new
one. However, if the change led to a desirable
improvement or outcome, you may consider
expanding the trial to a different area, or
slightly increasing your complexity. This sends
you back into the Plan phase and can be the
beginning of the ramp of improvement. - The Ramp of Improvement
- This is a schematic representation of the use of
the PDCA cycle in the improvement process. As
each full PDCA cycle comes to completion, a new
and slightly more complex project can be
undertaken. This rolling over feature is integral
to the continual improvement process.
19Sampling
- Sampling Plans originate from MIL-STD-105E and
are now within spec ASQ Z1.4. get a free copy
here old MIL STDs - Heres how to use 105E (simplistically)
- On Page 13 find the lot size range (the number
of units in the lot). Go to General Inspection
Level II (normal) column and find the
corresponding Letter code. - On Page 14 find the Letter code and find the
sample size (this is the number of units that
will be randomly chosen from the lot). Go to the
corresponding AQL (Acceptable Quality Level)
column and determine the Ac and Re numbers. - If Ac are not acceptable, the entire lot is
accepted. - If Re are not acceptable, the entire lot is
rejected. - All rejected units are repaired or replaced.
- Switching rules
- If 2 of 5 consecutive lots are rejected, use the
General Inspection Level III (tightened) column
(page 13). - If 5 consecutive lots are accepted at Level III,
return back to Level II. - If 10 consecutive lots are rejected at Level III,
perform 100 inspection. - If 10 consecutive lots are accepted at Level II,
go to Level I (Reduced). - If 1 lot is rejected at Level I, return back to
Level II. - Also see http//iew3.technion.ac.il/sqconline/mils
td105.html
20When to Sample? General Rule of Thumb Let p
nonconforming product (NCP) per lot. Let C1
cost of inspection and removal of NCP. Let C2
cost of rework if NCP went to the next step. Use
100 inspection if p gt C1 / C2 Use NO
inspection if p lt C1 / C2 Use Sampling if p
C1 / C2 Also based on supplier quality history
and criticality of the material. One needs to
ask what would be the result of allowing a
nonconforming item to continue through production
and/or on to the consumer?
21Seven Classical Quality Improvement Tools
- Checksheet (tally sheet)
- Control Chart (SPC)
- Process Flow Chart
- Histogram (frequency distribution)
- Pareto Analysis (80-20 rule)
- Scatter Diagram (variable relationship)
- Cause and Effect Analysis (fishbone)
221. Checksheet
- Also known as a tally sheet
- Used for simple data collection.
- Used to measure the frequency of events or
defects over short time intervals. - It illustrates, at a glance, what the most
occurring problems are.
232. Statistical Process Control (SPC)
- Every process varies.
- unusual variations are due to "special causes
Process is Out-of-Control - consistent variations are called common causes
Process is In Control - All control charts have three basic components
- a centerline, usually the mathematical average of
all the samples plotted. - upper and lower statistical control limits that
define the constraints of common cause
variations. (3s) - performance data plotted over time
- Things to look for
- The point of making control charts is to look at
variation, seeking special causes and tracking
common causes. Special causes can be spotted
using several tests - 1 data point falling outside the control limits
- 6 or more points in a row steadily increasing or
decreasing - 8 or more points in a row on one side of the
centerline - 14 or more points alternating up and down
- Reducing common cause variation saves money and
time.
- Types of control charts
- X bar R charts
- XmR charts
- C charts
- p charts
- np charts
- u charts
243. Process Flow Chart
- A pictorial representation describing a process
being studied. - Used to plan stages of a project or steps in a
process. - Provides people with a common language or
reference point when dealing with a project or
process. -
- The shapes
254. Histogram
- Sometimes called the Bell Curve.
- Lets you see the shape of a set of data - where
its center it, how far it spreads out on either
side, and location of outliers. - As the shape gets thinner, the variation is less.
- Used to determine process capability.
Normal Distribution
Bimodal Distribution
265. Pareto Analysis
- Used to graphically summarize and display the
relative importance of the differences between
groups of data. - Used to focus on critical issues by ranking them
in terms of importance and frequency. - 80/20 Rule About 80 of the problems are from
20 of the causes.
Focus on these three items (80)
276. Scatter Diagram
- Used to interpret data by graphically displaying
the relationship between two variables.
- Rules
- If the points cluster in a band running from
lower left to upper right, there is a positive
correlation (if x increases, y increases). - If the points cluster in a band from upper left
to lower right, there is a negative correlation
(if x increases, y decreases). - Imagine drawing a straight line or curve through
the data so that it "fits" as well as possible.
The more the points cluster closely around the
imaginary line of best fit, the stronger the
relationship that exists between the two
variables. - If it is hard to see where you would draw a line,
and if the points show no significant clustering,
there is probably no correlation.
- Validating "hunches" about a cause-and-effect
relationship between types of variables (ex is
there a relationship between the production speed
of an operator and the number of defective parts
made?) - Displaying the direction of the relationship
(positive, negative, etc.) (ex will increasing
assembly line speed increase or decrease the
number of defective parts made?) - Displaying the strength of the relationship (ex
how strong is the relationship between assembly
line speed and the number of defective parts
produced?)
287. Cause and Effect Analysis
- Brainstorm and write down all the potential
reasons why. - Continue asking why at least 5 times or until
there are no other (practical) reasons. - To visualize the discussion, construct a
Fishbone (aka Ishikawa or Cause-and-Effect)
diagram.
29Brainstorming
- Brainstorming is simply listing all ideas put
forth by a group in response to a given problem
or question. - To conduct a successful brainstorming session
- Make sure everyone understands and is satisfied
with the central question before you open up for
ideas. - You may want to give everyone a few seconds to
jot down a few ideas before getting started. - Begin by going around the table or room, giving
everyone a chance to voice their ideas or pass.
After a few rounds, open the floor. - More ideas are better. Encourage radical ideas
and piggybacking. - Suspend judgment of all ideas.
- Record exactly what is said. Clarify only after
everyone is out of ideas. - Don't stop until ideas become sparse. Allow for
late-coming ideas. - Eliminate duplicates and ideas that aren't
relevant to the topic. - Rapidly group ideas that seem to belong together
(called an Affinity Diagram). These groups can
be used as the Fishbones categories.
30Root Cause Analysis
- Will determine why the root cause occurred in
the first place. - Asks difficult and sometimes embarrassing
questions about how the organization is managed.
It may even be ignored for internal political
reasons. - Stops when youve exhausted all practical
causes. - The best candidates for root cause analysis are
those situations which are recurring the most and
use up the greatest amount of resource to
correct. - Extremely important because if done correctly, it
will prevent the problem from happening again. - 10 Steps
- Develop a problem statement
- Understand how the affected process works
- In a team setting (preferably) or individually,
ask why the problem occurred (5x) - Determine the Solution (Corrective Action) to
each Root Cause - Score and prioritize the causes by their
frequency, likelihood and ease to correct - Select the Root Cause(s) and attempt to validate
them - Develop a Plan to Implement the Solution
- Execute the Corrective Action Plan
- Verify that the Corrective Action was effective
- Monitor Process
31Team Dynamics
- Charter What is the purpose of the team?
- Set a clear Objective and Target.
- Leader Facilitates the teams actions.
- Champion/Angel motivates and provides
management support to remove obstacles and
provide funding/resources. - The Team maturity progression is
- Creating Cross functional include suppliers,
process, customers. - Forming High dependence on leader for guidance
and direction. - Storming Conflict occurs in interpersonal
relationships. - Norming Agreement and consensus is reached among
team, who respond well to facilitation by the
leader. - Performing The team has a shared vision and is
able to stand on its own feet with no
interference or participation from the leader. - Adjourning the break-up of the team, hopefully
when the task is completed successfully, its
purpose fulfilled.

32Malcolm Baldrigesee http//baldrige.nist.gov/
- Applying for the Baldrige Award is an opportunity
to examine your organization critically and
identify strengths and opportunities to improve. - An organization will accelerate improvement
efforts energize their employees gain an
outside perspective learn from feedback and
focus on results. - The Core Values and Concepts are embodied in
seven Categories, as follows - Leadership
- Strategic Planning
- Customer and Market Focus
- Measurement, Analysis, and Knowledge Management
- Human Resource Focus
- Process Management
- Business Results
33Malcolm Baldrige
- Core Values and Concepts
- The Criteria are built upon the following set of
interrelated Core Values and Concepts - visionary leadership
- customer-driven excellence
- organizational and personal learning
- valuing employees and partners
- agility
- focus on the future
- managing for innovation
- management by fact
- social responsibility
- focus on results and creating value
- systems perspective
- These values and concepts are embedded beliefs
and behaviors found in high-performing
organizations. They are the foundation for
integrating key business requirements within a
results-oriented framework that creates a basis
for action and feedback.
34TRIZ(see http//www.triz-journal.com)
- A problem solving tool based on logic and data
rather than intuition. - Eliminates contradictions (e.g., Training should
be thorough but not take any time) - Uses 40 Principals (see website)
- TRIZ doctrine
- Somebody, someplace, has already solved any
problem or one similar to it - Creativity means finding that solution and
adapting it to a current problem.
35Kepner-Tregoe'sFive-Phase Strategy Model
- Phase I Strategic Intelligence Gathering and
AnalysisA rigorous process is undertaken to
gather, organize, and analyze data on markets,
competitors, technology, and past performance to
ensure that the right information is used to
facilitate good strategic decision making. Phase
One provides an information base for strategic
decision making and an agreed-upon set of
assumptions about the internal and external
environments in which an organization will
operate during its strategic time frame. - Phase II Formulating StrategyA strategic
profile of the organization is developed for
guiding day-to-day decision making. This profile
defines key strategic elements including - The basis for competitive advantage
- The scope of the products and services that will
and will not be offered, and the markets that
will and will not be served - The relative emphasis and financial mix of the
future product/market scope - The source of new business and growth
- The capabilities needed to implement the strategy
- The business results to be achieved
- The critical issues (barriers to implementation)
to be resolved - Phase III Implementation PlanningAs a result of
formulating a clear strategy, many projects
emerge, the execution of which leads to
successful implementation of the strategy. The
creation of a strategic Master Project Plan is
the key output of this phase, providing a
detailed definition of each project, sequencing
projects, developing a schedule, and indicating
the required resource levels for each project.
The training of key staff in Project Management
techniques ensures successful implementation.
- Phase IV Implementing StrategyEven the most
elegant and robust strategic visions are
worthless without effective implementation. It is
the implementation phase of the process that
yields the tangible results sought by all
organizations. During this phase, planned actions
are taken, implementation is monitored, and the
plan is modified as circumstances change and the
strategy is revised. Also during this phase,
employees are given the necessary skills to play
their role effectively in implementation, with a
particular emphasis on project management and
decision making. Effective communication is at
the heart of flawless strategy implementation.
Every employee and external stakeholder is
briefed on the strategy with the intent of
creating understanding, commitment, and answers
to the question, "What's in it for me?" - Phase V Strategy Monitoring and UpdatingOngoing
review of the strategy is essential for keeping
the strategy vibrant and relevant as a key tool
in the continuous quest for success. Typically,
executive leaders are adept at reviewing the
operations and financial dimensions of the
business. The strategic review process is equally
important. Activities include determining if the
assumptions upon which the strategy rests remain
valid assessing if the strategic direction
continues to make business sense and keeping
abreast of progress toward implementation.
36Philip CrosbysZero Defects Approach
Why would a target be anything other than ZERO
Defects?
- Obtain Management Commitment Make it clear where

37Cost of (poor) Quality
- The costs associated with quality are divided
into two categories - costs due to poor quality and
- costs associated with improving quality.
- Prevention costs and appraisal costs are costs
associated with improving quality, while failure
costs result from poor quality. - Cost of quality comprises of four parts
- External Failure Costs associated with product
failure after the completion of the production
process. (e.g., customer complaints, returns,
recalls, penalties) - Internal Failure Costs expenses incurred before
the product or service is provided to the
customer. (e.g., repair, rework, scrap, data
corrections) - Appraisal Costs direct costs of measuring
quality. (e.g., inspection, test, calibration and
maintenance) - Prevention Costs associated with preventing
defects and imperfections from occurring. (e.g.,
process monitoring, SPC, audits, planning) - Phillip Crosby states that quality is free.
The costs related to achieving quality are traded
off between the prevention/appraisal costs and
the failure costs. Therefore, the
prevention/appraisal costs resulting from
improved quality, allow an organization to
minimize or be free of the failure costs
resulting from poor quality. Do it right the
first time. The total Cost of Quality should not
be gt 2.5 of your total Sales dollar. (reference

38FMEA(see steps at http//www.npd-solutions.com/fm
ea.html)
- Failure Modes and Effects Analysis (FMEA)
- a methodology for analyzing potential
- reliability problems early in the development
- cycle where it is easier to take actions to
overcome these issues, - thereby enhancing reliability through design.
- FMEA is used to identify potential failure modes,
determine their effect on the operation of the
product, and identify actions to mitigate the
failures. A crucial step is anticipating what
might go wrong with a product. While anticipating
every failure mode is not possible, the
development team should formulate as extensive a
list of potential failure modes as possible. - The early and consistent use of FMEAs in the
design process allows the engineer to design out
failures and produce reliable, safe, and customer
pleasing products. FMEAs also capture historical
information for use in future product improvement.
39PFMEA
- Process Failure Modes Effects Analysis.
- Is a systemized group of activities intended to
- recognize and evaluate the potential failure of a
product/process and its effect, - identify actions which could eliminate or reduce
the occurrence, - document the process, and
- track changes to process- incorporated to avoid
potential failures. - Is a living document. Is better to take actions
addressed to eliminate or reduce the potential
causes than implement controls in process. Is a
process which before hand tells you the potential
failure modes and their effects.
40TOC (Theory of Contraints)Ref The Goal by
Goldratt IBSN 0-88427-061-0
- The Five focusing steps
- 1. Identify the System's constraints.
- A process is analyzed so that a task or activity
that limits the productivity of an entire system
can be identified. A system constraint may be
identified by a long queue of work or long
processing times. - 2. Decide how to exploit the system's
constraints. - Decisions must be made on how to modify or
redesign the task or activity so that work can be
performed more effectively and efficiently. - 3. Subordinate everything else to the above
decision. (step 2) - Management directs all its efforts to improving
the performance of the constraining task or
activity and any other task or activity and any
other task or activity that directly affects the
constraining task or activity. - 4. Elevate the system's constraint.
- Additional capacity is obtained that will
increase (elevate) the overall output of the
constraining task or activity. This differs from
step 2 in that the added output comes from
additional purchased capacity, such as buying a
second machine tool or implementing a new
information technology. - 5. If, in the previous step, a constraint has
been broken, go back to step 1 but do not allow
inertia to cause a new constraint - Sets up a process of ongoing improvement. As a
result of the focusing process, the improvement
of the original constraining task or activity may
cause a different task to become a constraining
task or activity. Inertia could blind management
from taking steps to improve the system's output
now limited by a new constraint.(1)
41Process Capability
- Measures the ability of a process to produce a
product that will consistently meet design
specifications.

- Process Capability (Cpk)
- Relationship between the natural variation of
- the process and the design specifications.
- A Cpk of greater than one indicates that the
process spread is less than the width of the
specification. Potentially, this means that the
process can fit inside the specification limits. - Cpk gt 1.33 (capable)
- 1.00 gt Cpk lt 1.33 (capable with tight control)
- Cpk lt 1.00 (not capable)

42QFD(also see http//sern.ucalgary.ca/courses/sen
g/613/F97/grp2/report.htm)
- Quality Function Deployment (QFD) is a method of
listening to customers to learn exactly what they
want, and then using a logical system to
determine how best to fulfill those needs with
available resources. It is a product-development
tool that can systematically deploy customer
requirements into production requirements. QFD is
a team builder approach it ensures that everyone
works together to give customers what they want.
It gives everyone in the organization a road map
showing how every step, from design through
delivery, interacts to fulfill customer
requirements. - QFDs primary goal is to overcome three major
problems in traditional methods - disregard for the voice of the customer
- loss of information, and
- different individuals and functions working to
different requirements. - In QFD, these issues are addressed by effectively
answering the following questions - What are the qualities the customer desires?
- What functions must the product serve and what
functions must we use to provide the product or
service? - Based upon the resources we have available, how
can we best provide what our customer wants?
43APQP
- Advanced Product Quality Planning (used mostly
in automotive industry) - Phase 1 - Plan Define Program - determining
customer needs, requirements expectations using
tools such as QFD review the entire quality
planning process to enable the implementation of
a quality program how to define set the inputs
the outputs. - Phase 2 - Product Design Development - review
the inputs execute the outputs, which include
FMEA, DFMA, design verification, design reviews,
material engineering specifications. - Phase 3 - Process Design Development -
addressing features for developing manufacturing
systems related control plans, these tasks are
dependent on the successful completion of phases
1 2 execute the outputs. - Phase 4 - Product Process Validation -
validation of the selected manufacturing process
its control mechanisms through production run
evaluation outlining mandatory production
conditions requirements identifying the
required outputs. - Phase 5 - Launch, Feedback, Assessment
Corrective Action - focuses on reduced variation
continuous improvement identifying outputs
links to customer expectations future product
programs. - Control Plan Methodology - Discusses use of
control plan relevant data required to
construct determine control plan parameters
stresses the importance of the control plan in
the continuous improvement cycle.
44CMM
- The Capability Maturity Model for Software (also
known as the CMM and SW-CMM) has been a model for
judging the maturity of the software processes of
an organization. This model helps organizations
identify the key practices required to help them
increase the maturity of these processes. - Predictability, effectiveness, and control of an
organization's software processes are believed to
improve as the organization moves up these five
levels. While not rigorous, the empirical
evidence to date supports this belief.
1) Initial. The software process is characterized
as ad hoc, and occasionally even chaotic. Few
processes are defined, and success depends on
individual effort and heroics. 2) Repeatable.
Basic project management processes are
established to track cost, schedule, and
functionality. The necessary process discipline
is in place to repeat earlier successes on
projects with similar applications. 3) Defined.
The software process for both management and
engineering activities is documented,
standardized, and integrated into a standard
software process for the organization. All
projects use an approved, tailored version of the
organization's standard software process for
developing and maintaining software. 4) Managed.
Detailed measures of the software process and
product quality are collected. Both the software
process and products are quantitatively
understood and controlled. 5) Optimizing.
Continuous process improvement is enabled by
quantitative feedback from the process and from
piloting innovative ideas and technologies.
45HACCPHazard Analysis and Critical Control Point
- HACCP is a scientific system for process control
that has long been used in food/beverage
production to prevent problems by applying
controls at points in a production process where
hazards could be controlled, reduced, or
eliminated. - The program reduces risks to the customers. A
plant must have an effective HACCP system to
comply with regulatory requirements and prevent
adulteration of product. - See 9 CFR Part 417.
- Steps to meet HACCP are defined on the right.
