"What is material requirements planning?" is a question that often arises among manufacturers seeking to optimize their operations and gain a competitive edge in the global marketplace. To learn more about material requirements planning and its benefits for your business, let's explore MRP further with Viindoo in the following article...
What is Material Requirements Planning (MRP) with an example?
Material Requirements Planning (MRP) is a computer-based inventory management system that helps companies plan and manage their production processes. MRP assists in determining the amount of raw materials and components required for manufacturing products, and schedules the production process based on demand, inventory levels, and lead times. It takes into account factors such as production schedules, sales forecasts, and inventory levels to ensure that materials are available at the right time and in the right quantity. MRP software can help businesses optimize their inventory levels, reduce lead times, and improve production efficiency.
What is Material Requirements Planning?
For example, let's say a company manufactures bicycles. They have a production plan to manufacture 100 bicycles in the next month. The manufacturing software systems will take into account the inventory levels of all the required raw materials such as steel frames, rubber tires, and chains. It will calculate the amount of materials required for the production of 100 bicycles, including any additional materials needed to account for lead times and safety stock. The MRP system will generate a report or a list of materials needed to be ordered and the timing of those orders to ensure that the company has the necessary inventory to meet its production goals.

Why is material requirement planning important?
After having the answer to the question "what is Material Requirements Planning?" Next, we need to understand the importance of MRP. MRP is an essential tool for modern businesses that helps them plan and manage their production processes more effectively. By providing real-time information on inventory levels, sales forecasts, and production schedules, MRP enables companies to optimize their production process, reduce lead times, and improve customer satisfaction.
One of the key benefits of MRP is that it allows companies to maintain optimal inventory levels. By calculating the required quantity of raw materials needed for production, MRP helps businesses avoid stockouts and minimize excess inventory. This, in turn, helps reduce storage costs and improve cash flow.
MRP also helps companies reduce lead times by ensuring that the required materials are available when needed. By synchronizing production schedules with supplier lead times, MRP can help businesses shorten the time between order placement and product delivery. This, in turn, can help companies increase efficiency and reduce costs.

What is the difficulty in implementing MRP?
Implementing Material Requirements Planning (MRP) can be a complex and challenging process. Here are some of the difficulties that businesses may face when implementing MRP:
- Data accuracy: MRP relies on accurate data on inventory levels, lead times, and production schedules. If the data used in the MRP system is inaccurate, the production plan may be incorrect, leading to delays or excess inventory.
- IT infrastructure: MRP requires a robust IT infrastructure to manage the large amounts of data involved in the planning process. This can be challenging for businesses with limited IT resources or outdated systems.
- Training and expertise: MRP is a complex system that requires specialized knowledge and training to implement and manage effectively. Businesses may need to invest in training for their employees or hire outside experts to help with implementation.
The difficulty in implementing MRP
- Process changes: Implementing MRP often requires significant changes to existing business processes, including procurement, inventory management, and production planning. This can be difficult for businesses that are used to working with a different system.
- Cost: Implementing an MRP system can be expensive, requiring significant investment in hardware, software, and training. This can be a barrier for small businesses or those with limited budgets.
- Time-consuming: Implementing MRP can be a time-consuming process, requiring significant planning and testing before the system can be fully operational.
Overall, the implementation of MRP can be a significant undertaking for businesses. It requires careful planning, investment in IT infrastructure and training, and a willingness to make changes to existing processes.
The Main Steps Of MRP Process

What are the main steps of the MRP process?
Step 1: Master Production Schedule (MPS)
The MRP process begins with the creation of a master production schedule, which is a detailed plan that outlines the production requirements for a specific period. The MPS takes into account factors such as sales forecasts, customer orders, and production capacity to determine how much of each product needs to be manufactured during the planning period.
Step 2: Bill of Materials (BOM)
The BOM is a list of all the materials required to manufacture a product. The BOM specifies the quantity and type of materials required for each product. The MRP system uses the BOM to determine the materials needed for production and the quantity of each material required.
Step 3: Inventory Status
The MRP system checks the current inventory levels of all the materials required for production. It takes into account the quantity of each material currently in stock, the quantity on order, and the quantity on backorder.
Step 4: Material Requirements
Based on the MPS and BOM, the MRP system calculates the quantity and timing of materials required for production. The system determines the quantity of each material needed to complete the production plan and generates a schedule for when the materials are required.
Step 5: Purchase/Production Order
The MRP system generates purchase orders or production orders for the materials required for production. Purchase orders are generated for materials that need to be purchased from suppliers, while production orders are generated for materials that can be produced in-house. The MRP system takes into account lead times for both purchasing and production to ensure that the materials are available when needed.
Step 6: Monitoring and Control
The MRP system monitors the progress of production and adjusts the plan as needed to account for any changes in demand or inventory levels. The system keeps track of inventory levels and adjusts the production plan to account for any shortages or surpluses. The MRP system also monitors the progress of orders and adjusts the production plan as needed to ensure that customer orders are fulfilled on time.

Step 7: Reporting
The MRP system provides reports on inventory levels, production schedule, and material requirements to help businesses make informed decisions and optimize their operations. Reports can be generated for individual materials, products, or the entire production process. These reports help businesses identify potential bottlenecks in the production process and make informed decisions to improve efficiency and reduce costs.
In general, the MRP process is a critical component of modern manufacturing and inventory management. By providing detailed planning and control of the production process, businesses can optimize their operations, reduce costs, and improve customer satisfaction.
