Focus Groups Each participant: choose a stakeholder role that he/she is going to play during the Focus Group, and will express his/her interests A project representative will demonstrate the proposed technology using 1 or 2 case studies After each presentation: all stakeholders will be able to express how they perceive the presented future technology, and examine any conflicts of interest among different stakeholders and how these would evolve, as well as identify any critical control points 2012 The SESERV Consortium 5
