Staffing capacity planner

The chain is honest arithmetic, not a scheduler: workdays minus holidays minus leave gives available days per FTE, times hours per day gives gross hours, allocation cuts those to the work in scope, and the utilisation target cuts them again to productive hours. Demand matches roles by skill name ignoring upper and lower case, nothing smarter, so a typo makes demand unmatched and the tool says so instead of guessing. The FTE shortfall assumes a new person works at the same mix as the existing roles for that skill. It does not schedule individuals, track part-year calendars, or model hiring lead time. Nothing leaves this tab.
