RE: [scrumdevelopment] Re: User stories - has it worked for you?
- I apologize if you thought I was trying to imply that using User Stories (or anything other than use cases) was "jumping in and hacking." I simply meant to imply that most straight-out-of-college CS grads have little to no exposure or appreciation for any type of requirements gathering. However, I would also suggest that the use of use cases (or any type of development tool) does not indicate a lack or presence of flexibility. The process by which you develop software, and how it adapts to the different and changing constraints on the software system you're trying to construct, is the only thing that REALLY determines flexibility, IMHO.~Tim

Yes. For example, if they didn't really want it ever to work, then
the main path wouldn't be useful.
But otherwise ... it seems to me to be pretty useful in every case.

tossing a bunch of paper (probably electronic but you get my point)
over the wall to your QA guy is as good a way to do it as any.

Yes. I think the OP was talking about a full-on use case with all
its paths ... in fact I think he verified that. In that case, I'd
think that the main part of the case could be quite valuable.

to contaminate their minds with use cases, but instead would
contaminate their minds with flexibility. That's because I don't
recommend jumping in and hacking, I recommend jumping in and
implementing in a professional manner.
But to each his own ...
That's my opinion and I agree with it. -- Julio Santos
