| Welcome to Rough Cut Capacity Planning (RCCP)
A master production schedule (MPS) is based on forecasts and firm orders. Before this can be released to production, it must be checked to see if the targets in the MPS can in fact be achieved. Rough-cut capacity planning is one of the methods used to check the feasibility of the proposed MPS. RCCP is used to make a quick check on the capacity of the key resources to meet the proposed MPS.
During the RCCP process, a bill of resources is attached to each item on the MPS. A bill of resources is a listing of resources required to produce one unit of the item (including labour and machines / equipment, and so on). The MPS is exploded on the key resources (labour hours, machine hours, storage costs, etc.). It is important to use accurate lead-times in this process.
If the RCCP output indicates that the proposed MPS is not feasible, then either additional resources are proposed (for example, overtime, new machinery, out-sourcing), or the MPS is revised. |
