Vacancy Planning Capacity Analysis — "Do I Have Enough Staff?"
Vacancy Planning — Capacity Analysis
The Capacity Analysis tab in Vacancy Planning answers a structural question: "Given the demand I've entered, do I have enough staff to fill it?"
Use it before you go live with a new vacancy plan, or after a hire / resignation, to confirm the model is achievable.
Where to find it
Sidebar → Vacancy Planning → tab Capacity Analysis. URL: /staffing-vacancies (Capacity tab).
What it shows
After you've entered demand on the Grid tab:
- Total demanded hours per Craft Group — sum of every vacancy slot for the period
- Total available hours per Craft Group — sum of staff hours bands (min / max)
- Fillability % per shift pattern — how much of the demand can structurally be filled
How to read it
| Fillability | What it means |
|---|---|
| 100% | You have enough staff to meet this demand. IRIS should fill it cleanly. |
| 80–99% | Tight. IRIS will fill most cells but expect 1–2 gaps. Plan to use Open Shifts or agency. |
| < 80% | Structural shortage. Either reduce demand, hire, or budget for agency. |
What to do when fillability is low
- Reduce demand — re-examine whether every shift slot is genuinely needed.
- Hire — flag the shortfall to your line manager; the report makes the case.
- Bring in agency / casual — raise Vacancy Requests to authorise external cover.
- Re-tier scopes — if "1 RN with Resus" is impossible to fill, can a Senior Emergency RN safely cover? Use OR groups in the slot.
Tips
- Run Capacity Analysis BEFORE Apply. Discovering a 60% fillability after publishing is painful for staff.
- Hours bands matter. A staff member with min 30 / max 80 contributes their max to the supply side — re-check bands if the numbers look off.
- Capacity Analysis ignores leave. It's the structural picture, not "this fortnight". IRIS handles leave when it generates the Living Roster.
