Measuring AI ROI Without Fake Math

  5. 5. Measuring AI ROI Without Fake Math

Vendors love big savings numbers. Owners need honest ones. If you can't tell whether an AI routine is working, you can't decide whether to keep paying for it or expand it.

Measure three things, not one

  1. Time: minutes spent on the task, before and after.
  2. Quality: mistakes, rework or complaints, before and after.
  3. Speed: how long customers or teammates wait for the result.

Time alone misleads. A routine that saves 30 minutes but doubles mistakes isn't a win.
