the wall test.
If you could put exactly one number on the wall of an operations team, big enough that everyone saw it every day, what would it be?
It's a good question because it forces a confession. Most teams measure a dozen things and steer by none of them. The one you'd paint on the wall is the one you actually believe runs the business.
the usual suspects, and why I'd leave them off.
Volume feels important. Tickets closed, orders shipped, calls handled. But volume rewards being busy, and busy is not the same as good. A team can crush its volume number while quietly making everything worse.
Speed is seductive too. Fast is lovely, right up until fast means sloppy, and now you're doing the work twice.
Neither goes on my wall. They measure motion, not whether the machine is actually healthy.
Most ops metrics measure how hard everyone is running. The one worth painting on the wall measures whether the work is quietly getting harder or easier.
what I'd actually paint.
The number I'd put up is some honest version of "how much of our work had to be redone." Rework. The share of things that came back, got kicked back, needed a fix, didn't take the first time.
I like it because it's almost impossible to game in a way that doesn't help you. You can't fake your rework down without genuinely making the work cleaner. It quietly indicts every broken handoff, every fuzzy process, every place a human is patching a system that should just work. When rework climbs, something upstream is rotting, and it tends to show here first.
Chase it down and a strange thing happens. Speed and volume follow, because the biggest drag on both was always the stuff you had to do a second time.
the point of a wall number.
A metric on the wall isn't for a report. It's for the fifty small decisions a team makes every day without asking anyone. It tells them which way is up.
Pick one that rewards the work getting easier, not the people running faster. If your one number can go green while the operation gets worse, it's the wrong number. Take it down and paint a better one.
