Measurement

You're seeing it when a company measures employee productivity by hours logged and gets employees who sit at desks longer but accomplish less. The measurement shaped the behaviour, but not in the intended direction.

You're seeing it when a startup defines success by user signups but never measures activation or retention. The unmeasured dimensions — actual usage and value creation — deteriorate because they're invisible to the system.

Design your measurement systems knowing they will shape behaviour. Choose metrics that align with the outcomes you actually want. For every metric you track, ask what it might cause people to neglect — and consider measuring that too.

Walton was obsessive about measurement — but specifically about measuring the right things. He didn't just track sales; he tracked sales per square foot, inventory turnover, shrinkage rates, and individual store comparisons. He visited stores personally to verify that his measurements matched reality, knowing that numbers alone can deceive. Walton's Saturday morning meetings forced every executive to present their numbers and explain them in context. The system worked because Walton understood both the power and limits of measurement: he measured relentlessly but never stopped checking the numbers against direct observation. Founders should adopt this dual discipline — measure everything that matters, then verify that the measurements still represent truth.
