Capacity, diaries & utilisation
Capacity metrics tell you whether the diary can absorb demand—and whether front-of-house staffing matches clinical FTE. This hub groups utilisation benchmarks with the calculators that produce the numbers.
Utilisation, occupancy, no-shows, and turnaround answer different questions. Mixing them in one chart is how teams talk past each other in weekly meetings.
Define available sellable time, track DNAs separately, and only then debate whether you need more clinicians, more admin, or cleaner templates.
Focus for this topic
- Use one utilisation definition for at least a quarter.
- Pair no-show rate with reminder and missed-appointment value tools.
- Check admin-to-clinician ratio when diaries grow faster than reception cover.
