Lessons and Challenges

• Divergence in data
• Different products, different sites, different
  processes, different legacies
• Lack of common way of defining work WBS
• Your SE is not my SE
• Your life cycle is not my life cycle
• System of interest is not a common unit of
  measure nor is nominal requirement
• English is an ambiguous language
• I am building an LRU (a.k.a. box). How many
  scenarios do I have?
• Answer 7500!!!
• If you are wrong all the time, you are not
  wrong. Dan Ligett
• Prepare to set a policy
• Count in the way you intend to bid it
• Clear and present challenges
• Counting rules classification guidelines
• Reuse
• Requirement change
• Common vs. customer WBS
• Need a Management Champion
• We just got started
