Customer relationship management (CRM) involves capturing, storing, and analyzing customer information to better manage relationships and meet customer needs. Electronic CRM (ECRM) uses internet, email, wireless technologies to contact customers, allowing for personalized experiences and more efficient marketing.

For ECRM projects to succeed, companies must develop customer-focused strategies, reengineer processes, provide training and security, and implement within 90 days.
