  1. Moving to flow-basedsofteate developmentAn experience report by Jørn Ola Birkeland, BekkConsultng Report: LIU TENG YUAN

  2. Background The iteration Short iteration (two weeks) generalist developers v.s domain experts Fig 1: Day one of the iteration. Looking good Fig 2: Last day of the iteration. Not exactly what we’d planned

  3. Background The iteration Burn-down charts by ScrumMaster Retrospective (valuable , but suggestions ?) Fig 3. The burn-down at day one. Expected worst case best case and average case added. In this case the team had planned a little more than could be expected in the average case. Fig 4: The actual burn-down after the iteration. The team did pretty well, but was far from delivering all that had been planned. Scope change is very visible.

  4. Background The release cycle three 2-week iterations( test week , stage week ,development) test week: regression testing , user stories stage week: more regression testing , no errors , final verification problem: 1.test week was very stressful 2. 3rd deployment had to be carried out idea: next release cycle started in the stage week of the previous one.

  15. Summay and Conclusions 由上面的問券跟統計bug調查顯示, 移除不必需的程序不僅節省時間 工作者能在一件事情更專一、專一 stand-up meeting對象轉移 這使得目標更明確,造成有效的討論 更在最後的bug數量的結果上有顯著的改善,
