Projects that lack this hat (or don't fill it effectively), risk spending a lot of time and effort solving the wrong problem.
You can wear this hat if you're on a solo project, but it's tricky. The great trap is that you'll hear the first half (or third, or two sentences) of what the customer is asking for, and immediately swap in your "designer" hat and start thinking solutions. This is deadly, since a customer almost never gives a complete story on first presentation. Locking on to the wrong target can lead to a lot of wasted effort.
