Which planning module is used to validate the master production schedule at a medium-range horizon before detailed MRP runs?

• A. Capacity Planning
• B. Resource Requirement Planning
• C. Bill of Materials
• D. Rough Cut Capacity Planning

Answer: (D)

Rough Cut Capacity Planning is the step that validates the Master Production Schedule over a medium-range horizon by checking whether the planned workload can be absorbed by available capacity using high-level, aggregated data. It focuses on key resources like machines and labor, looking for bottlenecks or imbalances without getting into detailed routings or material specifics. This early feasibility check helps catch capacity issues before you run detailed MRP, which would drill down into exact materials, lead times, and scheduling details. If RCCP shows potential shortfalls, you can adjust the MPS or consider capacity changes before committing to costly, detailed MRP runs.
