MRP vs MRP II vs ERP: An Introduction for Manufacturers

The activity in manufacturing is complex. From maintaining accuracy in stock levels to controlling production functions, there are many tasks involved in manufacturing.

Before computers dominated the industry, manufacturers used to plan production and manage purchasing activities manually.

ERP software has become indispensable for businesses as it manages all of the core business departments and processes with just a few finger taps in a single system. Integrated with high-end machines, top-notch software, AI, and robotics, it allows organizations to simplify technology manufacturing requirements.

What is Manufacturing Requirements Planning?

Developed in the 1960s, Material Requirements Planning (MRP) systems for small manufacturers were designed to schedule and handle inventory (raw material, parts, and components, etc.). MRP is manufacturing-centric and focuses on controlling the level of materials required in the production process. It helps you get answers to these questions – What items are required for production? When it is required? How many are required?

Simply put, these are the objectives of MRP:

  • To maintain minimum required stock
  • To ensure raw materials are available for production and finished goods are ready for delivery on time
  • To seamlessly plan manufacturing activities

Black & Decker (an American manufacturer of power tools) used MRP for the first time in the year 1964.

Then, in the 1980s, MRP evolved into Manufacturing Resource Planning (MRP II) with added capabilities and functionalities.

Introduction to MRP II

As mentioned above, MRP deals with the manufacturing process. MRP II includes managing the functional operations such as coordination of different departments (manufacturing, finance, human relations, and production).

MRP II is comparatively a broader term. It manages resources (man, material, and machine) and addresses operational planning.

These are the basic modules/functionalities in MRP II:

MRP II

enables better relationships and visibility across suppliers and boosts the overall company’s bottom line through advanced planning, scheduling, and forecasting capabilities.

What is ERP?  

In short, ERP is the backbone of businesses.

ERP (Enterprise Resource Planning) is an extended version of MRP II, but a lot more comprehensive as it includes all core business functions and processes, including manufacturing operations. In addition to production and inventory, ERP systems also support financial and accounting management, sales, CRM, HR, service and support, and more.

ERP is an integrated suite of business management tools that provides a continuously updated, and often real-time depending on the solution, view of every department in the company. Whatever activity is done can be seen in a single database with ERP.

This is what makes ERP different from MRP and MRP II. Employees can work from any corner of the world and still collaborate with their colleagues, suppliers, and outsourcers.

ERP is different from MRP and MRP II because it offers:

  • Real-time visibility, insights, and collaboration
  • Automation of manual processes across the business
  • Single and consolidated database
  • A single and common user interface
  • Multiple modules to manage critical functions of an organization
  • Integration across functions, departments, and data

With ERP, you don’t need to invest in different software like CRM, accounting tools, or collaboration tools – you have everything in just a single system. This eliminates IT hassles and ensures a streamlined flow of work.

The global ERP software market is expected to reach  $41.69 billion by the year 2020. The features of MRP and MRP II are already encompassed in the ERP suite. This is the reason why businesses are adopting ERP solutions instead of disparate standalone tools.

Summary

ERP is a much more comprehensive and consolidated undertaking than MRP and MRP II.

MRP, MRP II, and ERP are developed for streamlining manufacturing and business operations in an organization. However, as time, technology, globalization, and overall complexity have evolved, new capabilities and functionalities in business management software also evolved – in this case from MRP to MRP II to ERP.

Currently, businesses are inclined towards investing in an ERP system that can help them reduce costs, increase profitability, improve internal collaboration, retain customers, and manage critical functions.
