This is the mentality that drives me crazy as a DBA. At my last job they were building a dashboard-type of report and wanted me to give them criteria on what was a problematic wait time -- even though we had 500 instances of SQL ranging from 4 GB to 256 GB, 2 CPU cores to 80, and from that be able to say that once a certain wait type went over a certain number that was always a problem. It. Just. Does. Not. Work. Like. That. The conversation ended something like this -- "Can't you just give me a straightforward number so I can make my dashboard for the business?" "If I could, you wouldn't need to have hired me. The whole reason I have a job is that one size does not fit all."
