Title: SIX SIGMA
1SIX SIGMA
- Striving for Near Perfection
2What is Six Sigma?
- Six Sigma is a management philosophy that
emphasizes - Setting extremely high objectives
- Collecting data
- Analyzing results
- to a fine degree as a way to reduce defects in
products and services.
3SIX SIGMA DEFINITION
- Six Sigma is
- a comprehensive and flexible system for
- Achieving
- Sustaining
- Maximizing
- business success.
4SIX SIGMA DEFINITION (cont.)
- Six Sigma is uniquely driven by close
understanding of - Customer needs
- Disciplined use of facts
- Data
- Statistical analysis
- Diligent attention to
- Managing
- Improving
- Reinventing
- business processes.
5SIX SIGMA AN INTRODUCTION
- Developed at Motorola in the 1980s as method to
improve process quality. - Initially created for process quality
- Now being used for business quality.
- A black belt can save a company 230,000 per
project and complete 4-6 projects per year. - Focuses on eliminating defects and maintaining
less than 3.4 per million opportunities. - Efficiency and lack of variation is key.
6The Six Sigma Philosophy
- The philosophy behind Six Sigma is
- If you measure how many defects are in a process
- you can figure out how to systematically
eliminate them - get as close to perfection as possible.
- In order for a company to achieve Six Sigma
- it cannot produce more than 3.4 defects per
million opportunities - An opportunity is defined as a chance for
nonconformance.
7Why do companies implement Six Sigma?
- The reason that companies use Six Sigma is to
increase profitability. - Sometimes however, the impetus to get started on
a Six Sigma process is brought on by customer
demands. Â
8How can Six Sigma help companies improve quality
and productivity?
- Six Sigma as a philosophy will create a
heightened awareness of the need for on-going and
everlasting quality improvement efforts. - Six Sigma as a process will provide employees
with the tools and skills they need to embrace
the Six Sigma philosophy. - By striving to achieve a six sigma level of
quality, companies reduce costs related to - Scrap
- Rework
- Inspection
- Customer dissatisfaction.
9How does Six Sigma work?
- Six Sigma starts at the top of an organization
- Requires constant attention by senior managers
who are responsible for establishing the Six
Sigma culture. - Senior management must enable the creation of an
infrastructure to support Six Sigma improvement
projects. Â
10SIX SIGMA THE STATISTICS
- Sigma (s) is the representation of the standard
deviation from the mean of a population. - Six sigma from the mean would make it nearly
impossible to perform a defective process. - Lean Six Sigma is merely a theoretical goal to
strive for.
11SIX SIGMA THE STATISTICS
12SIX SIGMA PRACTICAL EXAMPLES
- - 3.8 Sigma
- - 99 Accurate
- - 6.0 Sigma
- - 99.99966 Accurate
- 200,000 Wrong drug prescriptions per year.
- 2 Delayed or late flights per day.
- No electricity for about 7 hours per month.
- 68 Wrong drug prescriptions per year.
- 1 Delayed or late flight every 5 years.
- One hour without electricity every 34 years.
13SIX SIGMA WHO HAS USED IT?
- Motorola
- General Electric
- Xerox
- Honeywell
- Bank of America
- Siemens
- Allied Signal
- Dow
- Ford
- Etc.
14SIX SIGMA HOW HAS IT HELPED?
- GE saved 12 billion over five years and added 1
to its earnings per share. - Honeywell recorded more than 800 million in
savings. - GE produces annual benefits of over 2.5 billion
across the organization from Six Sigma. - Motorola reduced manufacturing costs by 1.4
billion from 1987-1994. - Six Sigma reportedly saved Motorola 15 billion
over the last 11 years. - Six Sigma enabled Bank of America to generate
more than 300M in first-year productivity gains.
15SIX SIGMA INDUSTRY EXAMPLES
- Automotive
- waste elimination
- improved forecasting processes
- improved fuel tank turnaround time.
- Chemical business improvements resulting in
1.5B increase within 3 years. - Healthcare
- turnaround times for lab results in ICUs
decreased from 53 to 22 minutes - reduced intravenous medication errors.
16SIX SIGMA INDUSTRY EXAMPLES
- Hi-Tech streamlined contract approval
procedures and increasing customer satisfaction
levels. - Financial restructuring major websites to take
attention away from costly human support centers. - Retail
- saving over 20 on procurement costs and thus
improving profit margin - improving marketing mix by applying experimental
design testing.
17DMAIC
- Define,
- Measure
- Analyze
- Improve
- Control.
- Incremental process improvement using Six Sigma
methodology. SeePronounced (Duh-May-Ick). - DMAIC refers to a data-driven quality strategy
for improving processes. - Is an integral part of the company's Six Sigma
Quality Initiative.
18SIX SIGMA DMAIC METHODOLOGY
- DMAIC Used for refining already existing
business processes. - Design - formally define the process improvement
goals that are consistent with customer demands
and enterprise strategy. - Measure - to define baseline measurements on
current process for future comparison. - Analyze - to verify relationship and causality of
factors. - Improve - optimize the process based upon the
analysis using techniques like Design of
Experiments. - Control
- setup pilot runs to establish process capability
- transition to production and thereafter
continuously measure the process and institute
control mechanisms to ensure that variances are
corrected before they result in defects.
19DMADV
- Define
- Measure
- Analyze
- Design
- Verify.
- Design for Six Sigma or new product/service
introduction. - DMADV is a data-driven quality strategy for
designing products and processes - It is an integral part of a Six Sigma Quality
Initiative.
20SIX SIGMA DMADV METHODOLOGY
- DMADV Used for creating entirely new products.
- Design - formally define the goals of the design
activity that are consistent with customer
demands and enterprise strategy. - Measure - identify CTQs (critical to qualities),
product capabilities, production process
capability, risk assessment, etc. - Analyze - develop and design alternatives, create
high-level design and evaluate design capability
to select the best design. - Design - develop detail design, optimize design,
and plan for design verification. This phase may
require simulations. - Verify - design, setup pilot runs, implement
production process and handover to process owners.
21DMAIC Versus DMADV
- We know that everything in business is a process,
right? - Sales people have a list of companies and
contacts that they work in a certain fashion to
produce a sale - Production receives an order and schedules the
manufacturing, the product is - Built
- Packaged
- Shipped
- Invoiced.
- When the packing department has a problem with
their process - should they fix it with a DMAIC or DMADV ?
22The Similarities of DMAIC and DMADV
- DMAIC and DMADV are both
- Six Sigma methodologies used to drive defects to
less than 3.4 per million opportunities. - Data intensive solution approaches. Intuition has
no place in Six Sigma -- only cold, hard facts. - Implemented by Green Belts, Black Belts and
Master Black Belts. - Ways to help meet the business/financial
bottom-line numbers. - Implemented with the support of a champion and
process owner.
23The Differences of DMAIC and DMADV
- When To Use DMAICThe DMAIC methodology, instead
of the DMADV methodology should be used when - a product or process is in existence at your
company but is not meeting customer specification
or is not performing adequately. - When To Use DMADVThe DMADV methodology, instead
of the DMAIC methodology, should be used when - A product or process is not in existence at your
company and one needs to be developed - The existing product or process exists and has
been optimized (using either DMAIC or not) and
still doesn't meet the level of customer
specification or six sigma level
24SIX SIGMA THE ROLES
Champions responsible for implementation across
organization.
Master Black Belts mentors and trainers to
black belts and others.
Black Belts focus on applying to individual
projects.
Green Belts employees utilizing six sigma.
25Roles required for implementation
- Six Sigma identifies five key roles for its
successful implementation - Executive Leadership
- Champions
- Master Black Belts
- Experts
- Black Belts
- Green Belts
26Executive Leadership
- Includes CEO and other key top management team
members. - They are responsible for setting up a vision for
Six Sigma implementation. - They empower the other role holders with the
freedom and resources to explore new ideas for
breakthrough improvements.
27Champions
- Are responsible for the Six Sigma implementation
across the organization in an integrated manner. - The Executive Leadership draws them from the
upper management. Champions also act as mentor to
Black Belts. - At GE this level of certification is now called
"Quality Leader".
28Master Black Belts
- Identified by champions
- Act as in-house expert coach for the organization
on Six Sigma. - They devote 100 of their time to Six Sigma.
- They assist champions and guide Black Belts and
Green Belts. - Apart from the usual rigor of statistics, their
time is spent on ensuring integrated deployment
of Six Sigma across various functions and
departments.
29Experts
- This level of skill is used primarily within
Aerospace and Defense Business Sectors. - Experts work across company boundaries,
improving - Services
- Processes
- Products
- For their
- Suppliers
- Their entire campuses
- Their customers.
30Black Belts
- Operate under Master Black Belts to apply Six
Sigma methodology to specific projects. - They devote 100 of their time to Six Sigma.
- They primarily focus on Six Sigma project
execution - Champions and Master Black Belts focus on
identifying projects/functions for Six Sigma.
31Green Belts
- Are the employees who take up Six Sigma
implementation along with their other job
responsibilities. - They operate under the guidance of Black Belts
and support them in achieving the overall
results.
32What are some mistakes companies make when they
implement Six Sigma?
- Here are the top reasons why Six Sigma does not
work - Thinking that six sigma is just using the tools
and ignoring the improvement cultural component.Â
- Seeing Six Sigma as a temporary activity rather
than a way of on-going business operations. - Not understanding the power and importance of
data and statistics.Â
33What are some mistakes companies make when they
implement Six Sigma? (cont.)
- Assigning responsibilities to implement Six Sigma
without giving the authority and training
necessary to carry through on Six Sigma efforts. - Not measuring processes or ignoring the story the
measurers are telling. - Not linking compensation to six sigma
performance.
34Six Sigma and Project Management
- Project management is a broad subject that
involves various tools and techniques for meeting
project requirements under the triple constraint. - Six Sigma is a more specific methodology used for
quality improvement and control. - Both concepts have similar best practices
- Identify and communicate w/ stakeholders
- Have a well-defined, established plan
- Conduct regular reviews
- Manage cost, schedule, and resources (triple
constraint)
35Six Sigma and Project Management
- Project management uses sound practices, tools,
and techniques on a project-by-project basis. - Consists of nine knowledge areas
- Six Sigma looks for the root cause of quality
problems or defects and attempts to prevent
recurrence, as opposed to a project-by-project
basis. - Focuses mainly on quality management and is more
data-driven -
36Six Sigma and Project Management
- Project selection an is important step of Six
Sigma - What makes a good Six Sigma project?
- There must be a quality problem or gap between
current and desired performance - Project should not have a clearly understood
problem - Solution should not be predetermined or apparent
37Six Sigma and Project Management
- Once a project is selected for Six Sigma, many PM
tools and techniques are used - Business case
- Project charter
- Requirements documents
- Schedule
- Budget
- Overall, Six Sigma methodology complements and
extends professional project management, but does
not replace it.
38Criticism of Six Sigma
- It can be expensive to implement
- Six Sigma training can take a long time and may
require outside consultants - It is not a quick fix
- It cannot survive without full executive support
- It involves change which can be challenging to
manage
39Tips for Implementing Six Sigma
- Leadership/top management support is critical
- All leaders should be trained as Six Sigma
champions. - Include Six Sigma training within the business
operating plan. - Select good consultants to train employees at all
levels. - Create a certification process and mentoring
program for all involved. - Create an effective communication plan. Answer
the questions - What is Six Sigma?
- Whats in it for the employees?
- What does it mean for the business?
40Strategic Six Sigma Process Management
- Because the philosophy was so effective in
improving process quality, it has been enhanced
and expanded in various ways. - Dell added R for Report Out
- American Express added L for Leverage
- Indicating expanded usage for communication and
enterprise strategy.

41Six Sigma Core Processes Value
- GE refocused Six Sigma efforts on core-processes,
the Game Changers that would add competitive
advantage and maximize the value creation for
stakeholders. - Shell Gas (LPG) expanded their Six Sigma
foundation to identify the high-impact projects
that would directly impact cost and revenue. - Understanding the critical components of a
business and identifying changeable elements,
companies can establish the metrics indicating
improvement.
42Six Sigma and Project Selection
- SoAnalyzing the procedural composition of the
business defines the measurements of success and
provides direction for strategic project
selection. - Knowing the value of a project portfolio will
inevitably steer - Project selection
- Scope definition
- Risk assessment
- And any project phase when decisions are made!
43Six Sigma Process Management replaces Get
Better with measurable factors that can be
precisely defined and valued.
For example A software company development team
may believe that updating their development tools
would be the greatest quality improvement
possible. An end-to-end core business analysis
could contradict that conclusion by revealing
that customers value stability over innovation.
The thorough permeation of Six Sigma practices
through an organization can allign strategic
vision and mission with the granular details of
business process improvement.
