What is ERP
ERP is the acronym of Enterprise Resource Planning. ERP utilizes ERP software applications to improve the performance of organizations'
resource planning, management control and operational control. ERP software is multi-module application software that integrates activities
across functional departments, from product planning, parts purchasing, inventory control, product distribution, to order tracking.
ERP software may include application modules for the finance, accounting and human resources aspects of a business.

CRM (Customer Relationship Management) and SCM (Supply Chain Management) are two other categories of enterprise software that are widely implemented
in corporations and non-profit organizations. While the primary goal of ERP is to improve and streamline internal business processes, CRM attempts
to enhance the relationship with customers and SCM aims to facilitate the collaboration between the organization, its suppliers, the manufacturers,
the distributors and the partners.
