At a previous employment we had a dashboard which showed which things were working (green) and which weren’t (red). Clear, immediate, useful. I had to write a script (green.bat) which we ran before management visited which made everything green. After they had gone, truth.bat returned us to reality.

I love numbers. They are where you find truth, but they can be abused.

I am in AWE. Also had job where I had to do "the commentary" for so many minor metrics, I did the shocking thing of asking were any of these actually useful?
