CRM process is a strong knowledge intensity process and customer knowledge is considered as one of the key strategic resources for the CRM success. Recent studies conducted in the fields of Knowledge Management and Customer Relationship Management has proposed that the two approaches can have great synergies. Based on this,we describe CKM as an ongoing process of generating,disseminating and using customer knowledge within an organization and between an organization and its customers to acquire and retain the profitable customers. Then,the CKM competence is studied and the tentative theoretical framework of CKM competence is set up,we propose that CKM competence should concern five key dimensions in particular: inter-functional cooperation; supportive organizational systems; cooperation with customers; supportive IT systems; organizational culture that support organizational learning and customer orientation.
