Build great metrics. Metrics show how the machine is working by providing numbers and setting off alert lights in a dashboard. Metrics are an objective means of assessment and they tend to have a favorable impact on productivity. If your metrics are good enough, you can gain such a complete and accurate view of what your people are doing and how well they are doing it that you can almost manage via the metrics alone.

度量是備受爭(zhēng)議的一個(gè)詞，因?yàn)樗呢?fù)面作用，很多人都不敢度量，其實(shí)好的度量是非常必要的，它能客觀地反應(yīng)一個(gè)人或一個(gè)組織是否運(yùn)轉(zhuǎn)良好。

In constructing your metrics, imagine the most important questions you need answer in order to know how things are going and imagine what numbers will give you the answers to them.

那我們應(yīng)該構(gòu)造哪些度量呢？我們要先問(wèn)自己最想知道哪些問(wèn)題的答案。比如你想知道團(tuán)隊(duì)目前的效率和質(zhì)量如何，那么就要圍繞這兩個(gè)方面建立度量，比如每個(gè)迭代能夠交付的用戶故事點(diǎn)數(shù)，每個(gè)迭代上線后產(chǎn)生的嚴(yán)重bug數(shù)等等。如果你想知道支持團(tuán)隊(duì)的服務(wù)質(zhì)量，就要看一個(gè)問(wèn)題從提出到響應(yīng)需要多少時(shí)間，一個(gè)問(wèn)題從提出到完全解決需要多少時(shí)間。

需要提醒的是構(gòu)造度量的輸入數(shù)據(jù)必須是準(zhǔn)確的，否則度量的結(jié)果很容易誤導(dǎo)人。另外不能盡信度量，要綜合各種數(shù)據(jù)和因素，全面地分析度量背后的真相。
