master production schedule

**Master production schedule** is the **time-phased statement of what finished output the factory commits to produce and when** - it bridges demand planning and detailed manufacturing execution. **What Is Master production schedule?** - **Definition**: MPS plan that specifies planned output quantities by product and period. - **Planning Role**: Serves as the primary commitment layer for downstream material and capacity planning. - **Input Dependencies**: Demand forecasts, confirmed orders, inventory targets, and available capacity. - **Execution Link**: Drives wafer-start levels, procurement signals, and production-priority alignment. **Why Master production schedule Matters** - **Commitment Clarity**: Establishes a single baseline for what the fab intends to deliver. - **Supply Synchronization**: Enables timely sourcing of materials and support resources. - **Capacity Feasibility**: Exposes overload risk before it becomes floor-level congestion. - **Financial Planning**: Supports revenue, inventory, and cost projections. - **Change Control**: Structured MPS updates reduce schedule instability and execution churn. **How It Is Used in Practice** - **Rolling Updates**: Refresh MPS on defined cadence with frozen and flexible planning windows. - **Feasibility Checks**: Validate plan against bottleneck capacity and cycle-time assumptions. - **Governance Review**: Use cross-functional S and OP style reviews for approval and adjustment. Master production schedule is **a core commitment instrument in operations management** - it aligns demand intent with executable factory output and creates the baseline for disciplined production control.
