Key performance indicator

Metrics generally used to evaluate factors crucial to the success of a project or organization. In project management, a KPI consists of tools that indicate if the project is meeting specific goals.

The Explain card

Plain English
A KPI is a measurable value chosen to show whether a project or organisation is meeting its most important goals. In project management, KPIs are the gauges that indicate whether the project is on track.
Example
An AI security programme tracks KPIs such as mean time to detect prompt injection attempts, percentage of models scanned before deployment, and the number of high-severity findings open beyond thirty days.
Why it matters
What gets measured gets funded. Good KPIs turn AI security from a vague worry into tracked, reportable progress; bad ones reward the wrong behaviour.
Hook
The dashboard gauges the board actually reads.
