Four Patterns of Success

• Scope management ? Asset based development
• Solutions need to evolve from user specifications
  AND user specifications need to evolve from
  candidate solutions.
• As opposed to getting all the requirements right
  up front.
• Process management ? Rightsize the process
• Process and instrumentation rigor evolves from
  light to heavy.
• As opposed to the entire projects lifecycle
  process should be light or heavy depending on the
  character of the project.
• Progress management ? Honest assessments
• Healthy projects display a sequence of
  progressions and digressions.
• As opposed to healthy projects progress to 100
  earned value with a monotonically increasing and
  predictable plan.
• Quality management ? Incremental demonstrable
  results
• Testing needs to be a 1st class, full lifecycle
  activity.
• As opposed to a subordinate, later lifecycle
  activity.
