What is the difference between MRP and MRP II? While both concepts share nearly identical names and both deal with manufacturing, these ideas are distinct, though related. MRP, material requirements planning, is used to manage manufacturing processes. An MRP system generally encompasses inventory control, bill of material processing, and basic scheduling. MRP II, manufacturing resource planning, can be thought of as a method to effectively plan all the resources of a manufacturing company.

An MRP system is oftentimes software-based and MRP II software systems are almost always modular in design. Both MRP and MRP II systems can be thought of as precursors to the enterprise resource planning (ERP) software systems that we are familiar with today. MRP and MRP II were both developed with the goal of centralizing and integrating business information to help production line managers make informed decisions and to make the entire production line more efficient.

To differentiate the two, an MRP system can be thought of as dealing primarily with manufacturing materials (hence the name “material requirements planning”) while MRP II is an information system that is concerned with coordinating all the aspects of the manufacturing process, which includes material, finance, and human relations and resources.

MRP and MRP II systems can be used separately, together, or in conjunction with ERP systems as well. Benefits include greater control over your production lines and easier access to real-time data. Both MRP and MRP II systems can give you the tools you need to streamline your manufacturing processes to achieve optimal efficiency.
