87%軟工 – Scrum之亂

莫名其妙進入軟體業兩三年後，三不五時聽到Scrum這名詞在耳邊繚繞，到底是在供尛呢？

但最近發現一件很有趣的現象，就是現在的開發團隊或是新創公司都在要求對Scrum認知，連自己公司的部門也是討論的沸(ㄅㄨˊ)沸(ㄓ)揚(ㄙㄨㄛˇ)揚(ㄩㄣˊ)。然後就這樣又過了半年多，讓我擠出了一點小小感想。

1.    盡信Scrum不如無Scrum?

還記得高職的基 (ㄅㄟˋ) 本(ㄉㄤˋ)電(ㄍㄤ)學(ㄏㄠˇ)老師說了句名言，「盡信書不如無書，盡信老師不如無老師」，這雖然是在開玩笑，但前半句話並非如此。在工作/職場中觀察下來，太多人糾結在Scrum這名詞或方法上面打轉，沒有真正思考自己的團隊是否已經能夠擁抱這樣的改變。並非質疑改變的不好，而是在這之前的基礎你打穩了沒！

2.    團隊(Real Team)

在軟體專案/產品開發中，管理者請盡可能去了解團隊中每一位成員的想法，取得與開發者的共識，彼此建立足夠的信任感。這件事非常重要，剛開始是非常辛苦且花時間的，但絕對是值得投資的一件事情。誠懇的溝通與銅鋰鋅很重要XD!

3.    人才(兵種)

在遇到的開發者中，有些人是屬於只要把計畫安排好的事情交辦給他，就會如期完成；有些人則是創意十足，適合創造與設計。所以請把對的事交給對的人去做絕對事半功倍！否則會變成，孔明當武將，張飛當智__的局面。

4.    理論(現實)

不論是哪一種理論，千萬不要死記死背。每個團隊有每個團隊的風格，每位成員有每位成員的特質，不會因為拿A公司成功的案例來B公司實施就會變成良藥，盲目的照本宣科只會害人害己。

5.    你準備好Scrum了嗎？

對我來說，要達成執行Scrum的條件是，每一位成員都能夠清楚的知道自己所扮演的角色，負責的工作項目，以及團隊目標。所以你今天Scrum了嗎?
