ERP computerized systems integrate a company’s entire business operation. Simply put, an ERP system binds together different computer systems for any large organization, with each department having its own system that communicates and shares information with the rest of the company’s systems. ERP integrates all key areas, including accounting, planning, purchasing, inventory, sales, marketing, PR, finance, human resources, and any other areas of importance to a company. Installing an ERP system enables a company to monitor and manage effectively the performance level of equipment, while simultaneously increasing uptime and increasing responsiveness, thus facilitating and fulfilling customer needs as well as streamlining company performance.

Although originally developed for large companies, ERP also benefits small and medium-sized companies and those involved in service rather than manufacturing, with ERP programmers creating a new generation of software that is easier to install, more manageable, and importantly, cheaper. The new systems are more modular, allowing installation to proceed gradually as a company evolves. ERP can also be outsourced, with the ERP manufacturer supplying the technology and the support staff required. This option has proved easier and cheaper than buying and implementing a whole system in-house. Hosted ERP or web-deployed ERP enables a company to run its ERP system through a web-hosted server and access it via the internet. This allows companies to reduce their IT investment in hardware and personnel.

ERP systems have also expanded through the evolution of technology to include new functions such as linking ERP to other software systems that affect the supply chain. This allows companies to view inventory and its status as it moves through the supply chain. ERP has also been adapted to support e-commerce by making order fulfillment and distribution easier and simplifying electronic procurement.

Computer security is included within an ERP to protect against both outsider crime, such as industrial espionage, and insider crime, such as embezzlement.

  • ERP systems require the installation of new technical support and training of staff, and they are expensive.

  • They desensitize operations procedures and rely on the whole system working.

  • Systems can be difficult to use or too restrictive.

  • The system may be overengineered relative to the actual needs of the customer, resulting in lack of personal service.
