What Is MRP? Explaining Material Requirements Planning

Businesses that manufacture and sell physical products have to keep track of many complex logistical details to facilitate operations. Being able to track and plan company activities is critical for making sure you have the right supplies to create and deliver a product at any given time. If you work in logistics and manufacturing, understanding material requirements planning can help you manage these details. In this article, we explain what MRP is and how it functions in the workplace.

What is a material requirements plan?

Material requirements planning (MRP) is a method for creating optimized production plans for manufacturers, usually using a software interface. Based on input from the manufacturer, MRP systems produce a material requirements plan, which outlines how much of each resource the company should purchase and when they should initiate each step in the production cycle.

The material requirements plan is a complex outline of a company’s strategy for production, supply and inventory logistics. It considers a range of external factors to determine an ideal plan for acquiring the right amount of materials to meet demand and implementing each manufacturing step on time.

It serves several key roles in the manufacturing process. Improving overall production efficiency is the primary goal for MRP, making it a useful tool for all stages of the manufacturing process. Some of the basic uses for systems include:

  • Developing a production schedule

  • Managing production expenses

  • Adjusting production capacity

  • Assessing the demand for raw materials

  • Determining how many products to manufacture

  • Optimizing the number of products in storage

  • Tracking the manufacturing process

  • Planning shipments

  • Monitoring supply orders

  • Identifying and correcting production delays


Manufacturers use it to become as efficient as possible, allowing businesses to order the optimal quantities of supplies and equipment. By using MRP, businesses can enjoy several benefits:

Improving communications

MRP systems make it easier for everyone involved in the production process to communicate with one another. Each person involved with assembling a product can use the MRP to understand how much they need to produce and in what time frame. MRP also assists with the scheduling process for orders and deliveries, providing a central hub where people can find updates on client and vendor interactions.

Automating production

One of the primary benefits of MRP is that it automates intricate production processes. It uses specific calculations to guide consistent workflows instead of requiring individual employees to manually determine their production standards. By automating company production strategies, MRP systems can save a significant amount of time while improving reliability.

Preventing human error

Having an MRP system in place is an excellent strategy for eliminating problems caused by human error. MRP software can automatically calculate the optimal procedures for any given situation, which helps protect against inaccurate estimations and miscalculations.

Meeting consumer demand

To be as profitable as possible, businesses need to be able to fulfill all of their customer orders. This involves having a high enough production capacity to fulfill demand. Effective MRP systems allow companies to assess consumer demand and use that information to gather the right amount of supplies. MRPs ensure that companies can follow through on all of their production commitments and deliver to customers promptly.

Avoiding over-ordering

Ordering too many supplies can be just as problematic as not ordering enough supplies. Businesses that order too many raw materials or have too much inventory can waste money on the surplus. It also costs money to arrange for proper storage for any excess and to dispose of expired or out-of-date products. MRP systems help manufacturers ensure they have all of their resources and infrastructure prepared without having unnecessary material waste or surplus inventory.

Limiting disruptions

By using MRP systems, manufacturers can schedule production to begin quickly after they secure the proper materials, which speeds up their overall workflow and allows for flexible, responsive manufacturing processes. This also makes it easier to identify disruptions to the production process and preventing them from having a negative impact overall.

Saving money

MRP systems also have cost control tools to ensure that manufacturers can continue production within their budget. The process of MRP identifies sources of waste that could have negative a financial impact on the company. Effective MRP allows companies to capture as many sales as possible without overwhelming their production capabilities or decreasing their profit margin.

How does material requirements planning work?

MRP systems work by assessing what manufacturers need, how much they need and when they need it. MRP systems interpret raw data from the manufacturer to create a production plan for various scenarios based on consumer demand. This involves using data analysis and software tools to reverse engineer the production process, using order details to determine all of the materials, parts and assembly processes involved with producing that order on time.

Once a manufacturer enters their raw information, the MRP system automatically checks current inventory levels and allocates resources to customer orders. The system then determines how much time it will take to fulfill the order and schedules labor and equipment resources for each manufacturing step. For products with multiple assembly steps, the MRP system creates an advanced production schedule based on how much time each step usually takes. Finally, the MRP system determines when the items will be ready for shipping.

Although the systems are highly automated to improve efficiency, you can also use them to manually view the status of various orders. they can send out alerts about production delays and create automatic recommendations for how to adjust existing orders to compensate for setbacks. MRP software can also generate production reports to track issues and identify manufacturing trends.

What information does an MRP system need?

To function properly, MRP systems need access to raw data. When setting up their MRP, businesses enter some basic parameters to help the system operate. MRP systems also need additional data to respond to changes in customer ordering habits or material availability. Once you enter the raw information into the MRP system, it can use data analysis to start preparing a material requirement plan. The primary types of information you’ll need for an MRP system are:

  • Product name: The product name in an MRP is an identifier for each product your company produces to keep the MRP organized and accurate.

  • Bill of materials: The bill of materials is a critical document for MRP. It is a list that includes all of the materials, parts and equipment necessary to produce a product.

  • Material specifications: Material specifications include details like shelf life, expiration date and storage conditions for both raw materials and finished products.

  • Inventory status information: Your system should be able to integrate with an inventory tracking system that shows where a finished product is between the final production step and delivery to the customer.

  • Production timelines: Include details about how long each step in production takes and what conditions you need to meet before the next step can begin.

  • Capacity limitations: Enter information about how many products your current production infrastructure can produce at maximum capacity. If you have minimum production requirements you should also include these details.

  • Sales forecasts: Sales forecasts help the MRP predict how much customers will order in the future. They operate most efficiently when they have specific incoming order information and a history of past orders.

  • Customer orders: MRP systems can adapt your production plan based on individual orders as well as overall trends. You can enter individual orders or work in batches.

How to use MRP in the workplace

Start using its systems in the workplace by following these key steps:

1. Select a software system

To implement MRP at your place of employment, you first need to find a good system that works for your needs. Start by researching the different MRP software providers that you can consider. Determine the features and specifications for search MRP provider and consider how they could support operations. You can invest in software that exclusively deals with MRP or you can seek out a complex software suite with certain features.

2. Audit production data

For MRP to work, you need to have high-quality data. If your information is inconsistent or inaccurate, the final material requirements plan will not provide the most efficient recommendations possible. Review your bill of materials, sales data and material specifications before instituting an MRP system. When working with incomplete or inconsistent data, spend extra time making corrections or gathering new information.

3. Train your team

Ensure all of your team members understand how the system works and how to use its features. Because the system is a centralized location for all production details, everyone on your team should be able to access the software and use its features when necessary. Train your production team on the restraints of the MRP and how to interpret different reports and features.

4. Closely monitor implementation

When first starting with an MRP system, carefully supervise the output of the system. You may have to make adjustments to troubleshoot the software to provide the results you want. Pay attention to order quantities and schedules and manually check critical information during the initial transition period. This step confirms that your MRP strategy works properly and provides the intended improvements in efficiency and productivity.

5. Generate frequent reports

To get the most out of it in the workplace, regularly run reports to find trends and patterns in your production habits. Because it is based on data analysis, MRP software typically includes many options for types of analytical reports. This provides you with the ability to apply manufacturing data to different scenarios and create projections for future needs.
