In modern supply chain management, successful planning depends on aligning business strategy with operational execution.
The MPR framework helps organizations balance demand, capacity, inventory, and resources while improving customer service and operational efficiency. Each stage builds upon the previous one, creating an integrated planning process that supports better decision-making across the entire supply chain.
1. Business Plan
The process begins with the Business Plan, which defines the organization’s strategic direction. This high-level plan establishes financial objectives, growth targets, market positioning, product strategies, and overall business priorities.
The Business Plan typically covers a long-term horizon of one to five years and serves as the foundation for all operational planning activities. It provides guidance on revenue expectations, investment decisions, expansion opportunities, and resource allocation.
2. Sales & Operations Planning (S&OP)
Sales & Operations Planning translates strategic business objectives into an achievable operational plan. At this stage, cross-functional teams from sales, operations, finance, procurement, and supply chain collaborate to balance market demand with supply capabilities.
S&OP creates alignment between customer expectations and operational capacity. Organizations review forecasts, inventory levels, production constraints, and financial targets to develop a consensus plan that supports both profitability and customer service.
3. Demand Management
Demand Management focuses on understanding, forecasting, and managing customer demand. This step combines forecasting techniques, market intelligence, customer orders, promotional plans, and historical sales data to generate accurate demand projections.
Effective demand management reduces uncertainty and improves responsiveness across the supply chain. Companies that maintain accurate demand visibility are better positioned to optimize inventory, improve service levels, and minimize operational disruptions.
4. Master Production Scheduling (MPS)
The Master Production Schedule converts demand plans into a detailed production timetable. The MPS determines what products will be produced, in what quantities, and when production will occur.
This stage acts as the critical link between customer demand and manufacturing execution. A well-structured MPS ensures production stability while maintaining flexibility to respond to changing customer requirements.
5. Rough-Cut Capacity Planning (RCCP)
Once the Master Production Schedule is developed, Rough-Cut Capacity Planning evaluates whether sufficient capacity exists to support the production plan. RCCP focuses on critical resources such as labor, machinery, production lines, and key work centers.
The objective is to identify potential bottlenecks before detailed planning begins. If capacity constraints are detected, planners can adjust schedules, increase resources, or revise production priorities.
6. Material Requirements Planning (MRP)
Material Requirements Planning calculates the materials, components, and raw materials needed to support the production schedule. MRP systems analyze bills of materials, inventory balances, lead times, and planned production orders to determine procurement and manufacturing requirements.
MRP plays a central role in ensuring materials are available when needed while minimizing excess inventory and carrying costs. It also improves supplier coordination and purchasing efficiency.
7. Capacity Requirements Planning (CRP)
Capacity Requirements Planning expands on RCCP by performing a more detailed analysis of production capacity at the operational level. CRP evaluates workload requirements for specific work centers, machines, and labor resources.
This step helps organizations validate whether production schedules are realistic and achievable. Detailed capacity analysis supports improved scheduling accuracy, resource utilization, and operational efficiency.
8. Production Activity Control (PAC)
Production Activity Control represents the execution phase of planning hierarchy. PAC manages the release, scheduling, monitoring, and control of production orders on the shop floor.
At this stage, organizations track actual production performance against planned schedules, manage work-in-process inventory, resolve operational issues, and ensure timely order completion. Effective PAC improves production visibility, reduces delays, and supports continuous operational improvement.
