Yoomah ERP, or enterprise resource planning, is a modular software system designed to integrate the main functional areas of an organization's business processes into a unified system. An ERP system includes core software components, called modules, that focus on essential business areas such as finance and accounting, HR, production and materials management, customer relationship management (CRM), and supply chain management. Organizations choose which core modules to use based on which are most important to their particular business. What primarily distinguishes ERP software from stand-alone targeted software -- which many vendors and industry analysts refer to as best-of-breed solutions -- is a common central database from which the various ERP software modules access information, some of which is shared with the other modules involved in a given business process. This means that companies using ERP are largely saved from having to make double entries to update information because the system shares the data, in turn enabling greater accuracy and collaboration between the organization's departments.
