请问有谁的公司用XP PROGRAMMNG开发系统？

我很笨。。。什么是 XP Programmng?

XP programming, a methodology approach for developing software. It exist b4 i born, 80 centurt sth kind.

instead of SDLC, XP progamming is one of the agile methodology to developing software.empahasize on code as documentation. instaed of using SDLC, (requirement->design->coding->testing) in the whole cycle, XP will to it iteratively, the activity will split in many iteration, every iteration doing 3 to 4 week, every iteration will do (requirement->design->coding->testing), like spiral model.

。。。我还是不懂楼主讲什么。

哈哈， 抱歉。。。

SDLC （SOFTWARE DEVELOPMENT LIFE CYCLE）is a waterfall approach, first requirement, then analysis, then design, coding then testing, then finish (got final product).

XP programming, a type agile methodology, like a spiral model, split the whole deveolpment process in some iteration, each iteration will be 3 - 4 week, every iteration will do all the process in the whole waterfall cycle (analysis, design, coding, and tesing) for some module, if cannot finish, function will be cut or finish at another iteration.

so compare to SDLC, at least can c some product at first, (imaging u write a super high end programmer , then after that, u find that this is not what customer want...this is one of the weakness of SDLC).

agile methodlogy like XP is more embrace CHANGE.

是不是tranditional life cycle?
example：
(phase 1=analysis) analysis-->design-->develop-->testing
(phase 2=design) design-->develop-->testing-->analysis
(phase 3=develop) develop-->testing-->analysis-->design
(phase 4=testing) testing-->analysis-->design-->develop
keep looping,when analysis phase,also do design,develop n testing,but the only different is time alocation

no no no...like this

iteration 1 (analysis-->design-->develop-->testing) -3-4 weeks (jan) (module A)
iteration 2 (analysis-->design-->develop-->testing) -3-4 weeks (feb) (module B)
iteration 3 (analysis-->design-->develop-->testing) -3-4 weeks (mar) (module B) if module b to large...then shift to iteration 3.
...etc.

but will do a sketch of the overall system, XP will do the 'spike'(the most critical module) first

我想楼主说的是
eXtreme Programming吧。
http://en.wikipedia.org/wiki/Extreme_Programming

本地应该很少（还没听说有）公司用吧。
是一种比较近与Agile Software Method / Modelling.和传统的SDLC有很大不同，
主要重于灵活性。

我也是一知半解。很久前在某网站的Articles和ebook看过。
