architecture - 在尝试确定是否应该重新开发系统时，我应该问什么问题？

Question

我参与了评估我们的一些系统是否需要从头开始重写，或者是否应该部分重写，或者是否应该继续使用上面的补丁。

为了更好地评估情况，我想知道我应该问自己和其他人哪些问题来帮助确定要采取的适当行动？

我建议你阅读 Things You Should Never Do, Part I .他为不重新开发提供了强有力的理由。

金钱报价:

It's important to remember that when you start from scratch there is absolutely no reason to believe that you are going to do a better job than you did the first time. First of all, you probably don't even have the same programming team that worked on version one, so you don't actually have "more experience". You're just going to make most of the old mistakes again, and introduce some new problems that weren't in the original version.

也许你应该问问自己，你是否对系统足够了解，可以在不重写的情况下解决问题。如果您不这样做，可以肯定地说您对系统不够了解，无法从头开始重新开发它。
