XP or not : no utter software development methodology

I've practiced XP for about four years, and I believe it's a excellent methodology for developing robust software, but recently I doubt what I got from XP, it become even worse when I read "Code Complete 2nd Edtion"(CC2E) those days

- XP said unit testing is very very very important, so we should testing first, CC2E said test is important but not so much

- XP said write code immediately, and improve software during iteration, but CC2E said if you don't get a clear/detail requirements before starting, you will be a loser, and improve software during iteration isn't a good way to follow, if we can do it well at starting, then it's the best way

- From my practice, I met delay delivery several times even we use XP, and also a bad stable status of our software, I know it's not all fault of XP, but from CC2E I do know XP isn't a silver bullet too, XP isn't suitable for every type of software development, it has its own suitable area

所以，最终不是要不要敏捷的问题，而是能不能在敏捷的成绩单上睡大觉的问题——显然答案是不能

我们的实践证明，XP很适合软件产品。
当然了，XP不是银弹，不能解决delay delivery。

话说回来， 微软的产品也是经常延迟的，
SO，没有任何证据表明微软的方式比XP好。

that's fine, could you please share some of your experiences here?

项目。XP完美适合的是项目开发，尤其是内部IT项目，ERP/CRM之类的。

对于软件产品，它不是不适合——它的很多最佳实践例如测试驱动、持续集成、结对编程等等仍然有效。它只是不足够。你还需要别的方法学和最佳实践。稍后我会写一个blog来详细说这个事情。

I do know you are an employee of ThoughtWorks(A XP company?), some of your softwares like "CruiseControl", "Selenium" are product or project? or how do you treat them inside your company?

I wish to read your blog...

其实你已经非常接近答案了。Steve McConnell是微软员工，而微软是一个做产品的公司。而XP是从C3项目脱胎出来的。这就已经很明显了。

Do you mean XP isn't suitable for product development but some framework/library/tools etc.?

From a table of CC2E, it said XP suitable for internet/intranet, etc. but not suitable for boxed software(product), if so, that's a great pity!
