Rough-Cut Capacity Planning (RCCP)

RCCP uses simplified resource data (a Bill of Resources) and works at the MPS level. CRP uses detailed routing data and works at the individual operation level within MRP. RCCP is faster and less data-intensive; CRP is more precise but requires complete routing information for every item.

Only the critical, constrained resources, typically the bottleneck machines or labor categories that determine throughput. Including too many resources makes RCCP as complex as detailed capacity planning. The value is in focusing on the constraints that actually limit production.

Planners have several options: extend the planning horizon (move production earlier or later), reduce the planned production quantity, add overtime or shift capacity, or push back on demand commitments. RCCP gives the lead time needed to exercise these options before a problem becomes a crisis.
