I'm running the team and every dial fights the other. Keep everyone fully booked and the work gets sloppy and people burn out. Ease off and the numbers slip and someone upstairs notices. I'm forever robbing one to pay another, and I can't seem to hold all three steady at once.
More people experience this than they realize.
You keep trading off billable hours, quality, and people and can't hold all three.
If this sounds familiar, the Library can help you find the bigger picture.
