Let's get an in-depth understanding of Material Requirements Planning (MRP) software in this blog:
What is Material Requirements Planning (MRP)?
MRP in business stands for Material Requirements Planning. It is a system used for efficient inventory management and production planning.
MRP ensures that materials and products are available for production and delivery to customers by calculating the quantities and timing needed for each component. It takes into account sales forecasts, bills of materials, and inventory data.
MRP is part of a broader category of solutions called Manufacturing Resource Planning (MRP II). MRP II includes additional features like resource capacity planning, shop floor control, and financial integration.
MRP helps determine what materials to order and when. By analyzing demand and supply, MRP generates a detailed production schedule. This schedule outlines the materials, parts, and components needed at each stage of production.
The main objectives of Material Requirements Planning (MRP) software are:
- Ensuring materials are available when required
- Maintaining the lowest possible inventory levels
- Planning manufacturing activities and purchase orders
MRP is especially beneficial for businesses with complex manufacturing processes. It helps manage materials with long lead times or dependent demand. Dependent demand items are components used to make finished products.
How does Material Requirements Planning work
In operations management, Material Requirements Planning (MRP) works by processing various inputs to generate a detailed production plan. The MRP system analyzes sales and demand forecasts, inventory levels, and bills of materials (BOMs) to determine the required materials and their quantities.
The Material Requirements Planning process involves the following steps:
1. Input Gathering
The MRP system collects data from various sources. This includes sales forecasts, BOMs, inventory records, and open orders.
2. Bill of Materials Explosion
MRP breaks down the finished product into its component parts and raw materials. This process, called BOM explosion, helps determine the quantities of each item needed.
3. Inventory Check
The system checks current inventory levels and compares them with the required quantities. It identifies any shortages or excess stock.
4. Lead Time Offsetting
MRP considers the lead times for each component. Lead time is the time required to procure or produce an item. MRP schedules the orders based on these lead times to ensure timely availability.
5. Generating Planned Orders
Based on the above information, MRP generates a schedule of planned orders. These orders specify the quantities and timing for purchasing or producing each item.
6. Capacity Check
MRP verifies if the planned orders can be fulfilled within the available production capacity. If capacity is insufficient, the system may suggest overtime or reschedule orders.
7. Order Release
Once the plan is finalized, MRP releases the orders to the purchasing and production departments for execution.
Material Requirements Planning software constantly updates the plan based on changes in demand, inventory, or capacity. This dynamic nature helps businesses adapt to fluctuations in these key variables.
MRP vs ERP
Material Requirements Planning (MRP) and Enterprise Resource Planning (ERP) are both software solutions used by businesses to manage their operations. However, there are some key differences between the two.
Material Requirements Planning focuses primarily on inventory management and production planning. It helps businesses plan and control their manufacturing processes. It ensures the right materials are available when needed for production.
On the other hand, Enterprise Resource Planning or ERP is a more comprehensive solution. It integrates various business functions into a single system. ERP modules can include:
- Financial management
- Human resources
- Customer relationship management (CRM)
- Supply chain management
- Manufacturing
- Project management
ERP aims to provide a unified view of a company's operations. It enables data sharing and collaboration across departments.
While MRP is a crucial component of manufacturing businesses, ERP is suitable for a wider range of industries. ERP can be used by manufacturers, distributors, service providers, and other businesses.
Another difference is the scope of the systems. MRP focuses on materials and production, while ERP includes a broader set of business functions. ERP includes MRP as a module, but also offers additional features like financial management and HR.
In terms of implementation, MRP is generally less complex than ERP. MRP can be implemented as a standalone system or as part of an ERP solution. ERP implementations are usually more time-consuming and resource-intensive due to their broader scope.
Who uses Material Requirements Planning software?
Material Requirements Planning (MRP) is used by a wide range of businesses, particularly those involved in manufacturing and assembly. Some common industries that benefit from Material Requirements Planning systems include:
1. Discrete manufacturing
Companies that produce distinct, countable products use MRP. Examples include automotive, electronics, and furniture manufacturers.
2. Process manufacturing
Businesses that produce products through a series of steps or formulas also use MRP. This includes food and beverage, chemical, and pharmaceutical companies.
3. Make-to-Order (MTO) manufacturers
MTO companies produce goods based on specific customer orders. MRP helps them plan and schedule production based on these orders.
4. Make-to-Stock (MTS) manufacturers
MTS companies produce goods based on sales forecasts and store them as inventory. MRP helps them maintain optimal stock levels and plan production accordingly.
5. Assemble-to-Order (ATO) manufacturers
ATO companies produce components and assemble them based on customer orders. MRP helps them manage component inventory and plan assembly operations.
6. Job shops
Job shop manufacturing is the type of manufacturing that produces small batches of custom products. MRP helps job shops manage the unique materials and processes required for each job.
In addition to manufacturers, other businesses that use MRP include:
- Distributors: Companies that purchase and resell products use MRP to manage inventory and plan purchases.
- Service providers: Businesses that offer services requiring materials, such as construction or equipment repair, use MRP to plan and manage their material needs.
- Retailers: Some retailers use MRP to manage their private label products or to plan inventory for high-demand items.
Regardless of the industry, businesses that deal with complex bills of materials, long lead times, or dependent demand can benefit from MRP.

Now let’s move on to understanding the key components involved in a Material Requirements Planning software.
The Key Components of Material Requirements Planning software
A Material Requirements Planning (MRP) system consists of several key components that work together to generate accurate production plans. These components include:
1. Master Production Schedule (MPS)
The Master Production Schedule or MPS is a high-level plan that outlines the quantity and timing of finished goods production. It is based on sales forecasts, customer orders, and inventory targets. The MPS drives the MRP process by specifying what needs to be produced and when.
2. Bill of Materials (BOM)
The BOM is a comprehensive list of all the raw materials, components, and subassemblies required to produce a finished product. It specifies the quantities and relationships between these items. The BOM is used by MRP to determine the material requirements for each level of production.
3. Inventory Records
MRP relies on accurate inventory records to determine the current stock levels of raw materials, components, and finished goods. These records include information about item quantities, locations, and statuses (e.g., reserved, allocated, or available).
4. Item Master
The item master is a database that contains detailed information about each item used in production. This includes item descriptions, lead times, suppliers, and lot sizing policies. MRP uses this information to generate purchase orders and production schedules.
5. MRP Engine
The MRP engine is the software component that processes the inputs (MPS, BOM, inventory records, and item master) to generate the output (planned orders). It uses complex algorithms to calculate material requirements, consider lead times, and adjust for inventory levels.
6. Planned Orders
Planned orders are the output of the MRP process. They specify the quantities and timing of materials to be purchased or produced to meet the MPS requirements. Planned orders are used to create purchase orders and production work orders.
Integrating MRP with Other Business Processes
Integrating Material Requirements Planning (MRP) with other business processes is essential for maximizing its benefits and ensuring a seamless flow of information across the organization. Some key areas where MRP integration can add value include:
1. Sales and Operations Planning (S&OP)
Integrating MRP with S&OP processes helps align production plans with sales forecasts and strategic goals. By sharing demand and capacity information between the two systems, businesses can make informed decisions about resource allocation, inventory levels, and production schedules.
2. Supply Chain Management (SCM)
Integrating MRP with Supply Chain Management (SCM) systems enables better coordination between suppliers, manufacturers, and customers. By sharing real-time information about material requirements, purchase orders, and delivery schedules, businesses can optimize their supply chain operations. This leads to reduced lead times, improved supplier performance, and better customer service.
3. Shop Floor Control (SFC)
Integrating MRP with SFC systems helps bridge the gap between planning and execution. By sharing production schedules and work orders, MRP ensures that the right materials are available when needed on the shop floor. SFC systems provide real-time feedback on production progress, quality issues, and resource utilization, which can be used to update the MRP plans.
4. Financial Management
Integrating MRP with financial systems, such as accounting or Enterprise Resource Planning (ERP), enables better cost control and financial visibility. By sharing information about material costs, inventory valuations, and purchase orders, businesses can accurately track their financial performance. This integration also facilitates better budgeting, cash flow management, and financial reporting.
5. Product Lifecycle Management (PLM)
Integrating MRP with PLM systems helps manage the entire lifecycle of a product, from concept to retirement. By sharing information about product designs, BOMs, and engineering changes, MRP ensures that the right materials and components are used in production. PLM integration also facilitates better collaboration between design, engineering, and manufacturing teams.
