A quantifiable unit which provides information about the success of a program, department, service, or outcome people care about achieving or maintaining. A government may identify a measure/metric by inventorying data that it already collects, collecting new data, or using validated external data.
Measures/metrics can focus on inputs, outputs, service quality, efficiency (e.g. cost per application processed); productivity (e.g. throughput); and effectiveness/outcomes (e.g. unemployment rate).
