Based on the theory of category learning, we put forward two customer socialization tactics: “rule-based customer socialization” and “situation-based customer socialization”, and introduce service knowledge types, exploring the effect of customer socialization on task commitment and satisfaction in Knowledge Intensive Business Services. It is found through experiment that under the rule-based customer socialization, providing codified knowledge instead of embodied knowledge leads to a higher service knowledge transfer efficiency and effectiveness, and under the situation-based customer socialization, providing embodied knowledge instead of codified knowledge results in a higher service knowledge transfer efficiency and effectiveness. Further, service knowledge transfer efficiency and effectiveness have a positive effect on task commitment and customer satisfaction.
