Industrial companies are forced into quick and effective product development of in order to comply with increasing competition. Flexible product definition is required together with very short innovation cycle. In order to achieve this, leading companies apply product model based lifecycle management of product information (PLM). In this way, demands for engineering stimulate development of product modeling. Latest developments in paradigm PLM 2.0 represent efforts in research for industrially applicable advanced knowledge based definition of product objects. The authors joined to these efforts by several works during the recent years. In this paper, they introduce one of their latest results. New method is applied for the control of product object definition. A special product model entity is introduced for the control of feature parameter definition. This entity is called as adaptive action and it carries proposed or decided human influence information and connects human request based product model extension by the authors with currently applied product model. Definitions of knowledge in latest professional industrial product models facilitate implementation of the proposed method in the PLM practice.
