Collaborative Product Commerce (CPC) is established to support the collaboration among the product design, product manufacturing, sales, marketing, services and so on. It is a one-off, dynamic process in order to respond the requirements of market. How to make a good notation about the requirements of CPC and collaboration relationships among the collaborators is becoming an important issue. It is a very important phase in the whole collaborative product commerce process, named as early requirements. This paper uses a goal and agent oriented approach (i* framework) to analyze and model early requirements of CPC. The collaborators in CPC are treated as strategic actors or agents and collaboration among them are depicted as dependency relationships. The model can be translated into formal language and suitable for automatic analysis that is used to verify early requirements and facilitate formal analysis in later phases. An example of an instance of CPC is used to illustrate.
