A KPI, or key performance indicator, is a metric that has been chosen as one of the few numbers that show whether a business, team or project is succeeding. Revenue against plan, gross margin, customer churn, on-time delivery, average waiting time. Every KPI is a metric; most metrics are not KPIs. The word “key” is doing the work: a KPI is watched, has a target, and someone owns it.
KPIs matter because attention is finite. A clinic could measure 200 things; its leadership team watches perhaps eight — utilisation, no-show rate, waiting time, revenue per session, patient satisfaction — and those eight shape the Monday meeting. A sales team runs on pipeline coverage, win rate and average deal size. When everyone knows the five numbers that matter, decisions get faster and meetings get shorter.
The common failures are too many KPIs, KPIs without targets, and KPIs whose definition drifts between teams. Rule of thumb: five to eight per team, each with a target and a comparison (last month, last year, plan), each defined once and used everywhere, each with a named owner. If a KPI has not changed a decision in six months, retire it.
In Klayara, a KPI appears as a headline figure with its comparison and trend, defined once as a metric and reused across dashboards, scheduled reports and AI answers. See the executive overview template and the KPI guide.
