Use one appointment as the unit
Choose a representative service and write what it needs throughout its occupied interval. A fictional repair appointment might require one qualified technician, one work bay and one diagnostic unit. Do not combine several services into an average appointment yet. An average can hide the fact that one service uses an asset another service never needs. Keep the first model narrow enough that a team member can explain every requirement without consulting a spreadsheet.
Count available rather than owned assets
Inventory is not availability. A business may own three machines while one is unavailable for maintenance. Four staff members may be present while only two are qualified for the selected service. Count the eligible, usable resources for the specific time interval. Mark an unknown count as unknown instead of entering zero or the total payroll. This prevents a precise-looking capacity number from concealing an unresolved operational assumption.
Find the binding requirement
For identical appointments needing one of each asset, simultaneous capacity is the smallest available count. If three staff share two rooms and one machine, the machine is the bottleneck. This arithmetic is an original planning simplification, not a prediction of a scheduler result. It excludes staggered resource use, breaks, travel and different service combinations. The worksheet makes those exclusions visible so a reader does not mistake a rough bound for a complete booking engine.
Validate both sides of the boundary
Test a request at the calculated limit and another beyond it using fictional appointments in an authorized test environment. Also try an unrelated service that does not require the scarce machine. It should not be blocked merely because another service consumes that asset, unless a shared constraint genuinely applies. Document the expected results before testing. A failed case means the model or configuration needs review; increasing the resource count just to make a slot appear is not a fix.
