• Chapter 4 - Six Sigma Revolution
• Tactical Six Sigma
• The project team should create a problem
  statement that is specific, measurable, describes
  the impact to the business, AND does not jump to
  causes or solutions.
• The project team needs careful guidance on
  defining project scope.
• A map of a process (process mapping) to be
  improved should be created that captures how the
  process operates today.

• Chapter 5 - Six Sigma Revolution
• Measuring Projects
• Determine ONE key measure of your process
  efficiency cycle time, cost, labor, or value.
• Use simple collection forms.
• Make sure your sampling is representative and
  random.

• Chapter 6 - Six Sigma Revolution
• Data and Process Analysis
• The goal of analysis is to determine and validate
  the root causation of the project teams original
  problem.
• At process analysis completion, the team should
  have greater information about the type of
  problem it needs to fix.
• The most used tool for brainstorming root causes
  Is the root cause diagram or fishbone.

• Chapter 7 - Six Sigma Revolution
• Root Cause Analysis Why Why Why . . .
• The most important step in analysis is validating
  root causation.
• Trial and error experimentation is a common
  method of experimentation, but is mostly error.
• Creating effects tables is a simple mathematical
  method to determine which factors are larger
  contributors to variation.

• The Hawthorne Studies
• A very famous series of productivity improvement
  studies carried out at the Hawthorne plant of
  Western Electric during the 1920s by Elton Mayo
  of Harvard University.
• One unintended outcome of the study was this
  Hawthorne Effect, which describes how people,
  singled out for a study, may improve their
  performance simply because of the added attention
  they receive from the researchers, rather than
  the specific factors being tested. The potential
  outcome of managerial revenge for negative
  responses is not a factor.
• This effect has been seen to be transferred to
  virtually any large company study or survey
  series. We can see the effects in simple
  performance survey scales of Favorable vs.
  industry ratings. There are often unkown or
  hidden factors that are operating.
• The other known result of the Hawthorne studies
  is that the positive effect of attention wore
  off over time.
• What that could mean for any company is that,
  year over year, results may decline and there
  will be no specific correlation to root cause.
  Thus the need for constant measuring TOOLS to see
  how any process is currently performing.
