Ideally, it addresses operational planning in units, financial planning in dollars, and has a simulation capability to answer what-if questions. It consists of a variety of processes, each linked together business planning, production planning (sales and operations planning), master production scheduling, material requirements planning, capacity requirements planning, and the execution support systems for capacity and material. Output from these systems is integrated with financial reports, such as business plan, purchase commitment report, shipping budget, and inventory projections in dollars. Manufacturing resource planning is a direct outgrowth and extension of closed-loop MRP.
