A Brief History of ERP

ERP's history dates back to the 1960s. The name ERP was first used by the Gartner Group in the 1990s. But enterprise resource planning systems actually have their roots in the manufacturing industry, back to the 1960s. Since then, growth has taken place to encompass many industries and job roles. It has become the term that defines the ERP software we know today by providing the unique integration of many different departments over the past time. Firstly, in 1960, as Inventory Management and Control, information technology and business processes entered our lives in order to maintain the appropriate stock level in a warehouse. By the 1970s, it led to the creation of Material Requirements Planning (MRP), which helps in planning production requirements and conducting appropriate inventory control. More and more manufacturers began to adopt MRP systems, and in the 1980s MRP systems evolved into what is known as MRP II or Production Resource Planning systems. With more production processes added to the original MRP systems, the first true ERP systems came into use in the 1990s. These systems have come in a format that includes other departments and functions such as accounting, finance and sales. Having these functions enabled previous iterations to go beyond basic inventory control and production processes. All these systems have laid the groundwork for ERP solutions, which we hear a lot today, by integrating multiple processes and departments into a single system. Besides commercial vendors, open source ERP systems have also evolved. These systems mainly meet the needs of small and medium sized enterprises.
