| 第十八章：沒有事情是一成不變的
選擇你的戰場
沒有事情是一成不變的，但沒有事情應該一直在變。
當然，我們要選擇我們的戰場。我們可能不會一直改變所有的程式，並同時添加更多的
新作品。我們一直都會找到讓人不開心的程式，並且無法馬上修改它們，無論有多少。
它需要工作量可能會很大。也有可能超過重構所需的心力。
我們或許有一定數量的
技術債務
，直到我們之後有機會改善為止。你應該將它放到專
案計畫，讓重大的債務變成工作項目，把它放到開發路線圖，而不是把它忘記，任其惡
化。
改愈多，愈沒效
這聽起來像個惡夢。誰有可能會一直與不斷改變的程式共事？追蹤許多同時改變的東西
就已經很難了，更不用說與它們相處！
但是，我們必須接受程式改變的事實：所有保持不變的程式都是一種負債。沒有程式不
需要修改。把一段程式視為可迴避的怪物，只會適得其反。[Page-162]
問題
1.
哪些屬性會讓軟體容易修改？你會自然地把軟體寫成這樣嗎？
2.
我們該如何在“沒有人擁有程式”與“有些人確實比其他人有經驗”之間取得平衡？
這會如何影響程式員的工作分配？
3.
每一個專案都有頻繁改變的程式，與小幅度改變的程式。後者可能很穩重，但是它很
少被用到，可能是它的設計很健全，可被外部的模組擴充，也可能是人們對它內部的
汙穢避之唯恐不及。這兩種剛性程式，你有多少？
4.
你的專案使用的工具是否支援程式的修改？你該如何改善它？
改愈多，愈沒效
