Scale Fail (part 1)
It continues to surprise me how much IT/sysadmin work is done by heuristic rather than actual measurements.<p>Applications slow? -> Add RAM<p>Database is slow? -> must be network/load<p>Service failures? -> reboot<p>It becomes very problematic in large IT organizations. Teams will play hot potato with issues, and all use excuses. Desktop support will blame the DB team, DB will blame the server team, then they all blame the network. All the while no one is actually measuring anything.
