What are the most important operations KPIs to track?

There is no universal top-ten, because the most important KPI is the one tied to the decision you make most often — and that depends on what you run. But nearly every operation benefits from covering four categories rather than over-indexing on one. For output, throughput and on-time rate tell you whether the work is getting done at the pace it needs to. For people, coverage versus demand is often the single highest-leverage operational metric, because understaffing quietly causes most downstream misses. For risk, SLA breaches and open incidents surface what is about to break before it does. For cost, cost per unit or per order keeps efficiency honest as volume changes. If you could only keep four numbers, one from each of those groups would give you a more complete picture than four output metrics stacked together. The mistake to avoid is measuring only what is easy to pull — usually output — while the leading, people, and risk signals that actually predict problems go untracked. Start from the decisions you make, choose the metric that informs each one, and you will end up with a short list that is genuinely important to your operation rather than a generic template.
