Overview of Different Types of ERP Systems, Architecture, and Modules

by Irina Kravchenko

First ERP systems came from MRP II that were developed in the 1980s. MRP II followed stock control and means material requirement planning. The evolution of the software defined the three types of ERP systems like MRP, MRP II, and a modern ERP. 

Stock control software was used in the 1960s as a set of information technology and work activities sustaining and monitoring a proper level of stock in the warehouse. Materials requirements planning was aimed to schedule the supply of raw materials and work operations according to the needs of production and other requirements related to the manufacturing of the final goods.

ERP applications followed MRP solutions which were used to coordinate manufacturing processes from product planning to distribution.

It is often presumed that ERP systems work best for large enterprises, however, today, a lot of vendors want to repackage them so that they are suitable for small and mid-size companies. Companies with sufficient in-house IT staff may integrate multiple software products, that’s why they can implement only a part of the ERP system according to their work needs and opportunities. Let’s see, what types of ERP modules can be implemented.

Types of ERP modules

Traditional Types of ERP Modules

Since ERP is a multiple modular application, it offers a lot of useful tools that business people can use to enhance the internal processes in their organizations. Here they are, the most popular modules:

  1. Supply chain management which includes all the processes related to supply, from planning to calculating the commission.
  2. Manufacturing is all about the flow of engineering, quality control, expenditure and cost control, etc. Production planning optimizes the utilization of manufacturing capacity, parts, components, and materials.
    resources using historical production data and sales forecasting.
  3. Project management helps handle billing, costing, performance.
  4. Financials manages all the assets including accounts receivable and accounts payable. The financial module is the core of many resource planning software. It can gather financial data from various functional departments and generate valuable reports such as balance sheets, general ledger, and quarterly financial statements.
  5. CRM module allows marketing and sales specialists to collaborate with clients in order to improve the relations between an organization and its clients or users as well as to understand the main problems people face when dealing with your organization.
  6. Human resources module helps HR specialists manage payroll, attendance and time, benefits, and other things related to human resources management. HR modules maintain a complete employee database including contact information, salary details, attendance, performance evaluation and promotion of all employees. The advanced module is integrated with knowledge management systems to efficiently utilize the expertise of all employees.

So, as you can see, ERP application handle a lot of processes like distribution, manufacturing, logistics, shipping, accounting, invoicing, and many other. Since ERP systems are enterprise-wide and cross-functional, departments across the company are able to collaborate in one place.

Types of ERP Architecture

According to Scott Hirst from SAP, ERP can be divided into two categories: monolithic systems and postmodern systems which both possess a certain number of characteristics. So, monolithic applications have the following features:

Monolithic system

  • Fits to requirements
  • Is developed with a single technology stack and a single vendor
  • Is not flexible to changes arising in business
  • An upgrade is needed to improve the system

Postmodern systems are more user-oriented and simple than their predecessors.

Postmodern system

  • Is user-centric
  • Is not a single product suite
  • Driven by social media, information, and clouds)

New types of ERP architecture are user-centric. They are simple to use to any user. Furthermore, these systems are agile which means that they are simplified, not containing redundant tables or other complicated things which were required for scalability in previous versions of different ERP products. Today, you may hear an abbreviation EAS which stands for enterprise application suite that can be used to denote formerly built resource planning systems.
