Enterprise Resource Planning (ERP) Systems started in 1970s the years’ when business and markets were heavily focused on mass production of materials and industrialization was on the peak. The so called enterprise, five to six decades back was in need of automation of industrial materials and their effective plus efficient management. The prime focus remained on materials and resources management.
In this fast changing business environment and heavy dependency of businesses on automated processes running using various IT Systems; the value and need for a reliable ERP System is constantly on rise.
ERP Systems have evolved over several decades and still continuing to evolve to become more fit for today’s business needs.
Legacy systems are generally any systems that are old systems built using software and hardware platform that is more than a decade old. Systems that are built using old programming languages like ‘COBOL’ and are running on mainframes, considered legacy systems. In some organisation such systems are still in use as they are complex, costly and difficult to replace. Legacy systems are difficult to interface with and make changes.
In organisations systems that are archived or not actively used and kept for audit purposes are also referred to as Legacy systems. These systems normally were built and used 7 or more years back and consist of business transactions and information that are of use for historical referencing. Older ERP systems are also termed as legacy if they are kept running and used for historical transactions referencing.
