but I think it's lousy for project management (or selling to a customer).
I do find that it requires a significant investment of the customer's time and experienced developers.
If your developers are arguing that unit testing is worthless because it tells you only what you already know (and yes I've had that conversation, twitch). Or if your developers admit that they're not going to put this one-off project into SVN (or any other software control system)...because the files are the on server, so nothing can happen to them (another fine conversation, twitch). In those cases, I'd worry about other things than Scrum first.
Those stand-up meetings can be very useful though -- daily telling your manager your blocked because he can't get off his tail to make a phone call...
Besides, as a Sys-Admin...you'd be a chicken...not a pig. :-)
