在敏捷开发Scrum中有很多估算的有效实践,这里有一个快速估算的方法号称Magic Estimation。它是如何Magic的呢?据说一两百个任务估算只需要十几分钟的时间,够Magic的吧。想知道是怎么做的吗?
简单的说就是分九步:
1. Start with the Product Backlog of user stories
2. Team will play, product owner will watch (and learn)
3. Lay the estimation estimation cards down on the floor, spaced out as per their values (as in the perspective picture above) e.g.
123 5 8 13 20 40
4. Hand out user stories to team
5. Explain rules: no talking, no non-verbal communication
6. Each team member estimates, place stories at points
7. Each team member checks estimates, re-estimate and move if desired (once all own cards are down)
8. Product owner marks fall-outs (too large or keeps bouncing)
9. Discuss fall-outs until reach agreement

太长了不好懂,是吗?其实简单点儿讲,要把估算做高效,拢共分三步:
1. 一套计划扑克,每人一套故事卡片
2. 各自估算,将故事放在对应的扑克点数上
3. 对分歧交大的故事进行讨论,达成一致 |
