一些研发管理定律

最近看到的几条定律，在工作当中了解一下或许有用。

1. 帕金森定律（Parkinson's Law）亦称“官场病”或“组织麻痹病”：工作会自动地膨胀，占满一个人所有可用的时间，如果时间充裕，他就会放慢工作节奏或是增添其他项目以便用掉所有的时间。 The demand upon a resource tends to expand to match the supply of the resource.
The amount of time that one has to perform a task is the amount of time it will take to complete the task.

2. 康威定律（Conway's law）：最终产生的产品设计等同于组织内和组织间的沟通结构。
organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations
（人力组织的结构要变更总是设计到各种既得利益者，不一定都能往最合理的方向演化。）

3. 布鲁克斯定律（Brooks' law）：往落后的项目中投入更多人往往使进度更加落后；来自《人月神话》。（PS:新增加人有学习曲线和沟通成本的增加）
According to Brooks, there is an incremental person who, when added to a project, makes it take more, not less time. Brooks adds that "nine women can't make a baby in one month".

4. 手表定律（Segal's law）：手表定理是指一个人有一只表时，可以知道现在是几点钟，当他同时拥有两只表时，却无法确定。
"A man with a watch knows what time it is. A man with two watches is never sure."
It refers to the potential pitfalls of having too much potentially conflicting information when making a decision.

5. 木桶定律又称短板理论，木桶短板管理理论：一只木桶能装多少水，完全取决于它最短的那块木板。从一个软件系统或者是一个产品、公司都很可能适合木桶理论；不过，也有反木桶理论。

6. 墨菲定律（Murphy's law）：凡事可能出错的事必定出错。事情往往会向你所想到的不好的方向发展，只要有这个可能性。
Anything that can go wrong, will go wrong.
不要存有侥幸心理~~~
