Customer relationship management (CRM) refers to the practices, strategies, and technologies that companies use to manage customer interactions and data in order to strengthen relationships with customers and drive sales growth. CRM systems help companies gain a complete understanding of customers, protect customer data, and allow access to customer information both in the office and on the road. While CRM can help identify leads, track the customer lifecycle, and improve forecasting, CRM implementations often fail due to unclear goals, lack of executive support, overcustomization, poor data quality, insufficient training, and team dynamics issues. Selecting and implementing CRM is hugely complex with difficulties at every stage.
