The split-pitch problem breaks ordinary calendars
Almost every pitch centre sells the same physical space in more than one configuration. One 11-a-side pitch becomes two 7-a-sides or three 5-a-sides depending on who is booking. A wall planner handles this by trusting whoever writes on it, and a generic room-booking tool handles it by treating each configuration as an unrelated resource — which means it will happily sell you the full pitch at 8pm and a 5-a-side inside it at the same time.
The correct model is linked resources: the full pitch and its component pitches know about each other, and booking any one of them removes the overlapping options from availability. This sounds like a detail until the Saturday you have two teams and one pitch, and it is the single most common reason pitch centres outgrow whatever they started with.
- Full pitch and 5-a-side pitches modelled as linked, not separate, resources
- Booking either configuration blocks the other automatically
- No reliance on staff remembering which pitch contains which
