Key Principles of Six Sigma at Xerox
ØEverything starts with the customer.  ØThe
infrastructure for cultural change is the most
powerful contribution of Six Sigma.  ØDecisions
about which projects to pursue must be based at
least in part on the potential impact on net
present value.  ØSustained improvement is
possible only with management engagement.  ØCEO
goals are translated to frontline projects and
coordinated through an organization of people and
technical resources.  ØA standard problem-solving
process and associated tool set provides the
means for basing decisions on data.

What does Six Sigma mean?  

• Phase I
• Early 1980s
• Pioneered at Motorola
• Statistical approach
• Measured DPMO
• Variation is the enemy
• Focused on
• Elimination of defects
• Improving product and service quality
• Reducing cost
• Continuous process improvement

6
What does Six Sigma mean?  

• Phase II
• Mid 1990s
• Revised by Jack Welch at General Electric
• Linked Six Sigma to business strategy and
  customer needs
• Strong measurement on bringing dollars to the
  bottom line
• Strong financial community involvement
• Project driven
• High potentials selected to be Black Belts
• Black Belts expected to deliver 250,000/year to
  bottom line (hard dollars)
• Black Belts promoted up after two years
• All senior leaders trained (Green Belt)
• Projects are sponsored by business leadership
  (Top Down)
• 2 of management committed full-time

What does Six Sigma mean?  

• Phase III
• 2000s
• Lean Six Sigma
• Caterpillar, Xerox, DuPont
• Combined lean manufacturing techniques and Six
  Sigma
• Benefit High speed, low cost

Six Sigma Improvement Model

• DMAIC Process
• Define describe the process,
• problem, opportunity
• Measure gather data
• Analyze listen to the data
• Improve develop solutions,
• design processes
• Control plan for stability

13
Six Sigma Design Model

• DMADV Process
• Define describe the process,
• problem, opportunity
• Measure gather data
• Analyze listen to the data
• Develop create the solution
• Verify does the solution work?

Reasons Six Sigma Deployments Fail

• Apathy from senior leadership
• Training not connected to projects
• Projects not connected to strategy
• Projects only focused internally
• Selecting available people
• Part time Black Belts
• No financial validation to bottom line
• People not recognized for their
• contributions

25
A Six Sigma Deployment Cannot Be Done Without
Consultants

• Training Materials
• Testing Materials
• Professional Educators
• Six Sigma Project Management Expertise
• (Master Black Belts)
• Credibility With Top Management
• Can Jump Start The Deployment

26
If properly driven by Top Management, Six Sigma
can have a dramatic impact on a companys
culture and how it aligns itself with its
customers
