  3. 3. Progressive Elaboration &quot;Because of the potential for change, the project management plan is iterative and goes through progressive elaboration throughout the project's life cycle. Progressive elaboration involves continuously improving and detailing a plan as more-detailed and specific information and more accurate estimates become available .&quot;

Editor's Notes

  • notes...
  • -may also have UI mockups/Prototypes/User research &amp; other artifacts leading into release. -time for Qualitative research: discover unmet needs
  • Rank the backlog - just enough to meet objectives (release date, MMF)
  • Sprint / Iteration / Rolling-wave Planning (V1 experimentation)
  • define Done
  • -PO may have ATs coming in; create more in planning -GWT format forces ATs to be broken-down somewhat consistently -too many ATs in a story is a smell that the story is too large
  • Dev + PO + [Designers].
  • define behavior (solution specific) before code - think thru for better design write more efficient code
  • focusing on behavior rather than state = less brittle -difficult to predict what comes out of emergent design / expensive to try
  • May expose new ATs. too many==smell
  • Opportunity for more user testing (task testing) PO verifies ATs - proclaims DONE.
  • May expose opportunities for improvement (new stories). Identify features with high risk of iteration &amp; rank them high.
  • automating all this
  • cucumber + rspec
