Our paper responds to the need of an Aided Team Building System (Aided VTB System). It focuses on virtual teams that are active in virtual design projects in the area of New Product Development (NPD). An extract of requirements of this Aided VTB System is presented that is based on the idea of Quality Function Development and its tool "house of quality". The fulfillment of the demand of the requirements by appropriate relevant and recent concepts and techniques as solutions is discussed with help of a sample survey of 34 virtual team leaders. One of the outcomes of the Aided VTB System is to provide recommendations, guidelines and even best practices to take a choice of web 2.0 tools and concepts and techniques in the domain of competence management.
