The Power of Master Production Schedule (MPS)
What is Master Production Schedule (MPS)?
The Master Production Schedule (MPS) is a vital planning tool used by manufacturing businesses to effectively manage production processes. It is a comprehensive and detailed plan that outlines the quantity and timing of products to be manufactured over a specific period. The MPS serves as a bridge between sales forecasts and production planning, ensuring that production meets customer demand while optimizing resource utilization.
In the business, we also hear the cases where MPS is issued by Customer as Subcontracting companies to deliver their materials as per the plan given by their Customer.
What are the modules in Master Production Schedule?
The Master Production Schedule comprises various modules that facilitate efficient production planning:
a. Demand Forecasting: This module involves analyzing historical sales data and market trends to predict future demand for products.
b. Inventory Status: This module provides an overview of existing inventory levels, helping businesses avoid stockouts or overstocking.
c. Resource Availability: The resource availability module considers factors like labor, machinery, and raw materials to determine production capacity.
d. Production Lead Times: This module calculates the time required to convert raw materials into finished products.
e. Order Management: The order management module tracks customer orders and aligns them with production schedules.
Why Your Business Needs a Master Production Schedule?
Implementing a Master Production Schedule is crucial for several reasons:
a. Efficient Resource Allocation: MPS optimizes the allocation of resources, minimizing idle time and ensuring smooth production.
b. Timely Delivery: MPS helps businesses meet customer demand promptly, enhancing customer satisfaction.
c. Cost Optimization: Proper production planning through MPS reduces wastage and lowers production costs.
d. Inventory Control: MPS prevents overstocking or understocking, leading to better inventory management.
It helps to manage manufacturing process as it’s the Actual demand of customer needs. Based on this, we need a Capacity planning with Demand Planning to enable effective master production schedule. Based on MPS, we check capacity requirements of Machines to fulfil the Customer demands. So we have manufacturing capacity and start manufacturing operations to complete Finished goods. Material requirements plan tool helps to check the current Inventory stock, total Sales demand, date of delivery of products and arrive at a plan to produce and deliver.
How Planning Department Uses Master Production Schedule?
The planning department plays a crucial role in utilizing MPS:
a. Demand Analysis: The planning department analyzes sales forecasts and customer orders to determine production requirements.
b. Scheduling: Based on MPS, the planning department creates production schedules to meet demand and optimize resources.
c. Inventory Management: The planning department monitors inventory levels to maintain adequate stock for production.
d. Collaboration: The planning department collaborates with various teams, including production, procurement, and sales, to ensure a smooth workflow.

What is the Difference Between Master Production Schedule and Forecasting?
Forecasting involves predicting future demand based on historical data and market trends. It serves as the foundation for MPS, as the MPS uses forecasting data to plan production.
The MPS, on the other hand, is a detailed plan that specifies when and how much to produce to meet forecasted demand.
What is MPS Formula? How to Arrive at It?
The Master Production Schedule (MPS) formula is a calculation used to determine the planned production quantity for a specific period based on forecasted demand, safety stock, and existing inventory levels. The MPS formula helps businesses maintain the right amount of inventory to meet customer demand while minimizing excess inventory or stockouts. Below is the MPS formula.
MPS = (Forecasted Demand + Safety Stock) – (Beginning Inventory + On-Hand Inventory + Work in Progress)
Let’s elaborate on the MPS formula with an example:
ABC Electronics is a company that manufactures smartphones. They use the MPS formula to plan their production for the upcoming quarter (3 months). Here are the relevant data:
- Forecasted Demand: Month 1: 1000 smartphones Month 2: 1200 smartphones Month 3: 800 smartphones
- Safety Stock: ABC Electronics wants to maintain a safety stock of 300 smartphones to account for unexpected spikes in demand or supply chain disruptions.
- Inventory Levels at the Beginning of the Quarter: Month 1: 500 smartphones Month 2: 400 smartphones Month 3: 600 smartphones
- On-Hand Inventory and Work in Progress: Month 1: 100 smartphones Month 2: 150 smartphones Month 3: 120 smartphones
Now, let’s calculate the MPS for each month:
Month 1 MPS Calculation:
MPS = (Forecasted Demand + Safety Stock) – (Beginning Inventory + On-Hand Inventory + Work in Progress) MPS = (1000 + 300) – (500 + 100) MPS = 1300 – 600 MPS = 700 smartphones
In Month 1, ABC Electronics should produce 700 smartphones to meet the forecasted demand and maintain the desired safety stock level.
Month 2 MPS Calculation:
MPS = (1200 + 300) – (400 + 150) MPS = 1500 – 550 MPS = 950 smartphones
In Month 2, the company should produce 950 smartphones to meet the forecasted demand and safety stock requirement.
Month 3 MPS Calculation
MPS = (800 + 300) – (600 + 120) MPS = 1100 – 720 MPS = 380 smartphones
In Month 3, ABC Electronics should produce 380 smartphones to meet the forecasted demand and safety stock level.
By using the MPS formula, ABC Electronics can ensure that they produce the right quantity of smartphones for each month, considering both customer demand and safety stock requirements. This approach helps them avoid overproduction or stockouts, leading to optimized inventory management and efficient production planning.
What are the Advantages of Master Production Schedule?
The benefits of using an MPS are,
a. Enhanced Productivity: MPS streamlines production processes, resulting in increased productivity and output.
b. Improved Customer Service: Timely order fulfillment through MPS boosts customer satisfaction and loyalty.
c. Better Decision-Making: MPS provides valuable insights for data-driven decision-making, ensuring efficient resource allocation.
d. Reduced Lead Times: MPS minimizes lead times, allowing businesses to respond quickly to changes in demand.
What are the Disadvantages of Master Production Schedule?
Despite its benefits, MPS may have some challenges,
a. Demand Variability: If demand fluctuates significantly, MPS may lead to overproduction or stockouts.
b. Complexity: Creating a precise MPS requires thorough data analysis and coordination among multiple departments.
c. Lack of Flexibility: MPS may become inflexible if changes in demand or disruptions occur.
