ERP software (or enterprise resource planning software) is an integrated system used by organizations to combine, organize and maintain the data necessary for operations. ERP systems merge an organization's key operations, including the manufacturing, distribution, financial, human resources and customer relations departments, into one software system. Selecting an ERP software package and implementing it correctly can be an extremely complex and intimidating process for many executives and project teams. When the ERP evaluation and implementation is performed correctly, ERP software can revitalize an organization by streamlining and synchronizing its separate departments into one unified software system.
