in reply to Benefits of the Specification
lachoy mentions a problem of client ego thinking they know what's best. In my experience here (but I'm saving the brunt of this rant for later) that the client really just wants something wiz-bang and wants you to PSI::ESI exactly what that is out of them. Development cycles in Japan flip back and forth on the order of hours or days at most (at least at my company).
The developer runs into a problem (frequently), management can answer it about 1/2 the time and otherwise calls the client. Sometimes management will save up a bunch of questions and take them to a meeting to get it all out. Meetings with clients are every week or so. I have more to say, but I'll save it for another post towards June when I've completed my year here and I can be as complete as possible.
