What a sac of vipers
This whole project stinks from the other side of the screen.
The customer doesn't give the data to allow the project to go forward, then doesn't want to look like it's paying for software (wtf ??), then gets all huffy and claims that 25% sales loss is IBM's fault.
I'm not defending IBM, but if what IBM says is true, that is one shitty customer.
On the other hand, IBM, please : talking to the Agile team is what you're supposed to do.
Unless IBM manages Agile with a Waterfall approach ? Hmm, that might explain a few things.
