Input Metrics vs Outcome Metrics
Input metrics count activity. Outcome metrics count success. Only one of them tells you if customers won.
Input metrics — time on page, searches, likes, app opens — measure activity, not success, and are dangerous when treated as goals. Outcome metrics measure whether customers actually accomplished something: task completion, reduced effort, fewer support needs. Customer-centric measurement starts with outcomes.
Input metrics are seductive because they are easy to collect and easy to move. Time on page, searches performed, likes, notifications sent, profiles viewed, app opens — all of these can rise while the customer experience gets worse. They measure motion, not progress.
- Task completion and task success rate
- Quality of outcomes, not volume of actions
- Reduced customer effort
- Reduced need for support
- Successful handoffs between human and system
A dating app makes the contrast concrete. Measuring profile views or matches sent rewards noise. Measuring conversations that continue meaningfully, and reciprocal interactions over time, rewards the thing customers actually came for.
Apply this
Reading about input metrics vs outcome metrics is one thing. Seeing where it applies in your journey is the useful part.
