Spitting facts, here.

I built a showback model at a prior org. Re-used shelfware for the POC, did the research on granular costs for storage, compute, real estate, electricity, HVAC maintenance, hardware amortization, the whole deal. Could tell you down to the penny how much a given estate cost on-prem.

Simple. Elegant. $0 in spend to get running in production, modest spend to expand into public cloud (licensing, mainly). Went absolutely nowhere.

Got RIFed. On the way out the door, I hear a whole-ass team did the same thing, using additional budget, with lower confidence results. The biggest difference of all? My model gave you the actual cost in local currency, theirs gave you an imagined score.

The complexity (cost of a team, unnecessary scoring) was rewarded, not the simplicity.
