Key Points

  • Without speakable results, AI investment won't continue
  • Measure on quality, speed, and cost axes with example metrics
  • Take a baseline; pair speed with quality; view net; tie to work
  • Don't mistake activity for results or ignore hidden costs

Design KPIs for AI Use

If you can't speak to "did adopting AI produce results," investment won't continue. Design so effects can be measured on three axes: quality, speed, cost.

Example Metrics per Axis

  • Speed: work time, lead time, processed items per person
  • Quality: error rate, rework rate, customer satisfaction, pass rate
  • Cost: labor-reduction amount, AI usage cost, net effect after offset

Design Principles

  1. Take a baseline first: without pre-adoption values you can't speak of effect
  2. Don't speak by speed alone: faster but lower quality is counterproductive. Always pair with quality
  3. View net: subtract AI cost and operating labor from reduction effect
  4. Tie to work: meaningful units of that work, not abstract KPIs

Easy Traps

  • Mistaking "number of uses" for results (activity ≠ results)
  • Reporting only speed without measuring quality degradation
  • Not accounting for hidden cost (verification/fix effort)

Key Point

Design KPIs as "baseline → net of quality/speed/cost → work units." Only once made measurable does AI investment ride continuous decision-making.
