Scrum 的八項缺點

Scrum/Agile Failings or the Theses of Uncle Bob Martin
http://www.infoq.com/news/2010/02/scrum-failings

Uncle Bob在二月時提出對Scrum的批判, 每點都直擊要害, 我自己是十分認同. 不過令人興慰的, 到目前為止, 有不少先知對這些缺點, 提出不少解法.

1. No technical practices
- Scrum只給了管理上的建議, 但是沒有給開發人員技術上的建言
- Scrum必須借助XP的practices, 像是:TDD, Continuous Integration, Acceptance Testing, Pair Programming, Refactoring.

2. 30 day sprints are too long
- 很多團隊認為2 weeks比較合適, 會比較快得到feedback

3. The tendency of the scrum master to arrogate project management powers.
- 有很多Scrum Master把Scrum搞成micro management
- 也許是不應該用master這個字, 改成用coach也許比較不會讓Scrum被誤用

4. The Certification in CSM is unfortunate
- 在Scrum中常把這個role搞成變成一個person.常常都是同一個人當scrum master
- 應該要學XP的coach觀念, 要輪替到不同的團隊, 而不是都是同一個scrum master

5. Scrum provides insufficient guidance regarding the structure of the backlog.
- Scrum對backlog的structure著墨很少
- 經過一段時間的學習, 我們了解到要對backlog做拆解: Epics->Themes->Stories->Tasks

6. Scrum carries an anti-management undercurrent that is counter-productive.
- Scrum過度強調團隊自我管理. 自我管理的團隊固然很好, 但是有其侷限性.
- 仍然需要管理團隊適時輔助

7. Automated Testing.
- 沒有高品質的test automation, 很難縮短iteration的時間, 並且也不知道甚麼時候會做完

8. Multiple teams
- Scrum 和agile都對於scalability沒有很好的處理.
- 雖然很多實踐者都有一套做法, 但是並沒有一致的結論

不知各位看倌, 對於這些缺點有沒有不同的看法呢?
