作者是一位在IBM工作, 並且相信PMBok的人. 他經由書上或是師徒的關係, 學到有關Scrum的知識. 並且根據他懂的部份, 來執行scrum. 他覺得Agile/Scrum是以比較不負責任的方式在工作.
並且在網路上, 聽到很多人套用Scrum後, 有以下的抱怨
- “Scrum doesn’t work”
- “Scrum makes the devleopers life easier but hurts the customer”
- “The lack of overall budget/timeline is a killer (only look 1 sprint forward, really)”
最近他參加Jeff Sutherland的Certified Scrum Master課程. Jeff提出了一個概念: ScrumBut.
什麼是SrcumtBut呢? 雖然你在做Scrum, 但是不是真的Scrum. 因此你無法獲得, 真正執行Scrum團隊所得到的好處.
Jeff 也提出了一個測試, 評估你是否是ScrumBut. 這測試是的玩法是, 選擇每向你目前的作法, 把它所想對應的分數加總, 然後把你的分數除以9.

如果你的分數平均不到6，你可能沒有真正在套用Scrum. 如果你的分數不高, 你可以看看那一個項目處理不好, 來特別加強它.
