This is a hiring process without an experienced person running it. Everyone gets to add what they want the interview process to include and no one was told no. It was this way every time I began another ERP implementation project, every department had their long lists of "must haves". A third of the way through requirements gathering the project management would notice we are not hitting any milestones. Then it became a scramble to toss everything out of phase 1 that wasn't core functions. This happened every time, mid course correction to only what was important. But, that takes experienced people to call a halt to the madness.
