Which planning method integrates all resources of a manufacturing company, including unit and dollar planning, with what-if simulations, and includes processes such as S&OP, MPS, MRP, and CRP?

• A. Sales and operations planning
• B. Manufacturing resource planning (MRP2)
• C. Just-in-time planning
• D. Master scheduling

Answer: (B)

Manufacturing resource planning (MRP2) is the approach that brings together every resource of a manufacturing company into one integrated plan. It expands beyond merely calculating material needs (MRP) by adding capacity planning and financial planning, so you can see not only how many parts are required but whether there is enough capacity, labor, and money to meet the plan. This integration lets you run what-if simulations to test how changes in demand, lead times, or capacity would impact the entire operation and its budget.

In practice, MRP2 ties together the main planning components: S&OP (the overall market and operations balance), the Master Production Schedule (which translates the plan into specific production quantities over time), MRP (determining the material requirements to support that schedule), and CRP (evaluating capacity to ensure those production plans are feasible). Because it includes both unit planning (quantities) and dollar planning (costs, budgets), it provides a holistic view of the enterprise's operations and financials, enabling coordinated decisions across departments.

Other options don’t cover this full integration. Sales and operations planning focuses on aligning aggregate demand and supply but doesn’t inherently couple the detailed material, capacity, and financial planning with what-if analysis in a single system. Just-in-time planning emphasizes waste reduction and flow, not end-to-end resource coordination with financials. Master scheduling targets production timing and quantities but doesn’t inherently integrate capacity planning and financial implications.
