I come from industrial maintenance, factories, production lines, and I'm trying to understand how data center teams handle things differently. Specifically around scheduling PMs across multiple contractors, tracking what actually got done, and dealing with the inevitable handoff chaos. I'm curious: do most of you rely on a CMMS, or is it more spreadsheets and email in practice? And when a contractor says "it's done," how are you actually verifying that? Happy to chat here or if anyone's open to a quick call or swapping a few messages, I'd really appreciate it.
