When people babble about "guesstimates" I remind them they do not need that word. And estimate is an estimate and that is wrong. if it was right we might call it data.
For the next week or two, let’s do an experiment.
Whenever someone says “story point” or “velocity,” quietly in your own head translate it to “made up numbers.”
“I’ve noticed your made up numbers have dipped.”
“We need to raise our made up numbers.”
Mmmmhmmm.
