KPIs Don’t Just Measure Performance

KPIs don’t just measure performance.

They shape behavior.

That is why a metric can be technically correct and strategically damaging at the same time.

Years ago, I was involved in work where the strategic objective was clear:
Improve net cash flow.

The analysis pointed to a real opportunity in the supply chain: reduce inventory days on hand.

That was the right financial focus.

Inventory was tying up cash. The business needed to improve working capital. The organization needed a clear measure, accountability, and a feedback loop.

So the KPI became quarterly inventory DOH.

And the KPI worked.

Maybe too well.

Teams focused intensely on making sure the measure showed up green on the quarterly scorecard.

But something else started happening.

Manufacturing costs were not improving the way they should have been.
When we dug deeper, the issue became clear:

The KPI was driving quarter-end behavior, not better operating behavior.

To hit the quarter-end DOH target, production would get pulled back to reduce inventory levels.

Then, shortly after quarter-end, production would ramp back up to meet customer service expectations, on-time delivery requirements, and order-complete targets.

The result?

Overtime.
Inefficiency.
Operational churn.
Higher cost.

The inventory KPI was directionally right.

But the behavior it created was wrong.

The answer was not to abandon measurement.

It was to improve the system.

Look at the KPI in context.
Understand the trade-offs.
Identify the knock-on effects.
Adjust the measure when the learning tells you to.

In this case, moving toward a daily average DOH view created a better signal. It reduced the incentive to manage the optics of quarter-end inventory and pushed the organization toward more sustainable operating improvement.

That is the role KPIs should play.

Not just accountability.

Learning.
Adaptation.
Better decisions.

Strategy needs metrics.

But metrics need judgment.

Because when a KPI becomes the goal, the business can win the scorecard and lose the outcome.

What KPI have you seen drive the wrong behavior?
