CRM focuses on optimizing profitability through enhanced customer satisfaction and loyalty by automating and enhancing customer-centric processes. It evolved from cost reduction strategies in the 1980s to growth strategies and marketing led approaches in the 2000s. Electronic CRM (eCRM) expands traditional CRM techniques by integrating electronic channels like web and wireless technologies into the overall enterprise CRM strategy to measure, create, and increase income while reducing costs for each customer segment to generate greater lifetime value. eCRM systems use customer analytic software, data mining software, campaign management software, business simulation, and a real-time decision engine to achieve these goals.
