ERP (in English Enterprise Resource Planning), also called Integrated Management Software (PGI), are applications whose purpose consists in coordinating all activities of a company (so-called vertical activities such as production, procurement, or rather horizontal activities such as marketing, sales forces, management of human resources, etc.) around the same information system.
Integrated Management Software generally provide Groupware and Workflow tools to ensure transversality and flow of information between the different services of the company.
Much more than just software, ERP is a true project requiring full integration of a software tool within an organization and a specific structure and therefore involves significant engineering costs. On the other hand, its implementation in an enterprise requires significant changes in the working habits of a significant part of the employees. It is therefore believed that the cost of the software tool accounts for less than 20% of the total cost of implementing such a system.
