KPIs, Metrics and Measurements
Three levels of measurement, kept distinct: a measurement is a timestamped record of an event, a metric is a calculated value combining measurements, and a KPI is the critical few metrics designated as key indicators of performance.
Teams use these three words interchangeably, and the confusion is expensive. It leads to dashboards crowded with "KPIs" that indicate nothing, to metrics nobody can trace back to real data, and to arguments about numbers that are really arguments about definitions. Getting the hierarchy straight is unglamorous and quietly transformative: it is the difference between measuring the business and drowning in it.
The three levels
Start at the bottom. A measurement is raw: a timestamped record of a single event, a sign-up at 14:03, a ticket closed, a payment taken. It is the source data, and it is not yet meaningful on its own. A metric is calculated: a named value combining measurements, often a ratio or rate, activation rate, average resolution time, monthly recurring revenue. It turns raw events into something comparable over time. A KPI is a metric promoted: one of the critical few you have designated as a key indicator that the business is on track. Every KPI is a metric; almost no metrics should be KPIs.
The critical-few discipline
The most common failure is KPI inflation: a dashboard of forty "key" indicators, which is a contradiction in terms, because if forty things are key, none of them is. A KPI earns its status by three tests: it has an owner, it has a threshold that says when to act, and crossing that threshold actually triggers a decision. A number with no owner, no threshold and no consequence is not a KPI; it is decoration, and it is costing attention every week it stays on the board. Prune ruthlessly, and what remains actually indicates something.
KPIs measure health; OKRs drive change
The sharpest distinction is between KPIs and OKRs. KPIs measure ongoing performance, the health of business-as-usual, the things that should stay good. OKRs target a specific change you are trying to create. A KPI answers "is the engine running well?"; an OKR answers "what are we rebuilding this quarter?" You need both, and you need to know which is which, because managing a change goal like a health metric (or vice versa) is a reliable way to fail at both. The two are connected by a lifecycle: a KPI that breaks, or that strategy wants pushed to a new level, graduates into an OKR, and returns to the scorecard with a new threshold when the work is done.
Arrange and surface them
Metrics are most useful in relationship, not isolation. Arrange them in a metric tree so cause and effect are visible, and surface the critical few on a KPI scorecard that a team actually reviews. The scorecard is the home of business-as-usual, watched with thresholds and owners, which is exactly what frees your OKRs to focus on the few breakthrough changes that will not happen on their own.
"Support is slow" is an argument. Broken down: measurements are individual ticket timestamps; the metric is median resolution time (14h); the KPI is median resolution time with a threshold of 8h and an owner. Now it is actionable, and if it breaches, an OKR to fix it can be spun up deliberately.
What is the difference between a metric and a KPI? +
Every KPI is a metric, but a KPI is a metric you have designated as critical, with an owner, a threshold and a decision attached. Most metrics should stay metrics; only the critical few become KPIs.
Should KPIs be OKRs? +
No. KPIs monitor ongoing health; OKRs drive specific change. A KPI that breaks or needs pushing to a new level can graduate into an OKR, then return to the scorecard afterwards.
How many KPIs should we track? +
Few. If everything is key, nothing is. Keep the critical handful that have owners and thresholds and drive decisions; move the rest to supporting metrics.

Clear measurement is the foundation everything else stands on. We help you sort the critical few from the noise, build the scorecard, and connect it to the OKRs that drive real change.
