Manufacturing Resource Planning(MRP II) Evaluation

Manufacturing Resource Planning is an integral part of an information system used by businesses. It has evolved from the initial Materials Requirements Planning (MRP I) systems by incorporating additional data, including employee and financial requirements.

The integrated information system of MRP II concentrates, accumulates, and processes the information so that the third party can leverage this information for scheduling, design engineering, inventory management, and cost control in manufacturing.

Material Requirements Planning and Manufacturing Resource Planning are the predecessors of Enterprise Resource Planning(ERP), a procedure-oriented methodology in which manufacturers smartly manage all the critical aspects of their business.

An ERP management information system unifies various areas like planning, purchasing, inventory, sales, marketing, finance, and human resources. ERP is commonly associated with software, and numerous extensive applications have been developed to assist companies in properly implementing Enterprise Resource Planning (ERP).


Manufacturing Resource Planning is a computer-based integrated information system that devises precise and accurate production schedules. It leverages real-time data to synchronize the arrival of raw materials with machine and labor availability.

Its advent aim is to fix the shortcomings or constraints of Material Requirements Planning (MRP I). To maintain backward compatibility, it contains all the critical features of MRP I. It is often a helpful and relevant tool to enhance the core functionality of the Enterprise Resource Planning (ERP) system.

By the end of the 1980s, manufacturers and business owners realized that they needed a specific kind of software that could easily incorporate into their accounting system and prophesy the amount of inventory required to accomplish a particular task.

Manufacturing resource planning is a leading software-based integrated information system that boosts the overall performance of the organization. It relies on a sales forecast-based helpful system in scheduling raw material deliveries and quantities.

Aside from all these managerial uses, it has been extensively used to precisely predict the amount of human capital, machinery, and IT Infrastructure required to achieve a sales target.

How to Create an MRP II System?

To create an MRP system, consider the following main resource management and manufacturing processes.

The Master Production Schedule (MPS)

Master Production Schedule (MPS) is a planning tool used to help manufacturing businesses manage production schedules, inventory levels, and customer demand. The MPS outlines the quantity of each product that needs to be manufactured within a certain time frame based on the forecasted demand.

The MPS considers many factors, such as sales forecasts, inventory levels, lead times, and capacity constraints, to ensure that production schedules are optimized and meet customer demands.

The Inventory Status File (ISF)

An Inventory Status File (ISF) is a document that provides up-to-date information on a company’s inventory levels. It contains information such as the quantity of each product on hand, the location of each item in the warehouse or storage facility, and any outstanding orders or backorders.

ISF is used by businesses to help them manage their inventory levels and ensure that they have enough stock to meet customer demand.

By regularly updating the ISF, companies can quickly identify any potential shortages or overstocks and take action to adjust their production or reorder levels accordingly.

The Bill of Materials (BOM)

A Bill of Materials (BOM) is a comprehensive list of all the materials, parts, components, and sub-assemblies needed to manufacture a product. It outlines the quantity of each item required to produce the final product.

The BOM is an essential tool for manufacturers, providing a detailed breakdown of all the raw materials and other inputs needed to create a specific product.

Shop Floor Management

This feature tracks manufacturing Key Performance Indicators (KPIs) and monitors all activities on the production floor, ensuring real-time oversight and efficiency in the manufacturing process.

Order Management

This functionality enables companies to efficiently handle customer purchase orders, issue sales orders, and monitor the entire production, shipping, and delivery cycle, enhancing customer satisfaction and operational transparency.

Cost Management & Accounting

When selecting MRP II software, organizations must ensure it includes robust capabilities for tracking the costs of direct materials and labor involved in the production process, aiding in precise cost control and financial planning.

Production Capacity Planning

Effective workforce and asset management functionalities are crucial for determining resource availability, facilitating accurate production capacity planning, and optimizing resource utilization.
