RM technologies and changing customer behavior affect segmentation and revenue management. Proper segmentation involves meaningful groups that represent valuable customers, not assumed preferences. CRM data can help identify these segments. Integrating CRM and RM through segmentation can increase understanding, monitor behavior, and build trust. This requires matching RM to CRM technologies and defining important customer features. Experts advise seeking help with segmentation to minimize failure and maximize benefits like increased profits through targeted pricing. Multidimensional segmentation into smaller groups accounts for multiple customer criteria and purchasing situations.
