Procurement teams are not the ones doing the work, they are centralized bureaucratic functions to which requests go in and products come out. They have a habit of buying stuff that actual practitioners would never buy: inappropriate to the use case, known poor quality, off-brand knockoff of something practitioners actually like, etc. Any latitude in the requirements will be used in the dumbest possible way. There’s a whole cottage industry of products for government that meet naively written specs but are actually crap.

Imagine hiring web developers with only HR on the interview loop, no manager or team rounds.
