waiting for solid requirements

This is exactly the situation. Except that my team consisting of consultants just "started", instead of trying to scope out the constraints and larger picture. I joined a month or so after.

Six months, and the result so far of their exploration is a fairly uninteresting happy-path use of some technologies, barely related to the task that had unclear requirements. Turns out the work done is unsuited for it. Boggles the mind how much resources are wasted on such things.

Feels extremely unrewarding to have worked, relatively hard, for half a year, and the fruits of my labour is... getting to the point where the actual problems are solved. Which one could have done from day one, if one had started in a team without wrong preconceptions, or, no team, for that matter.
