PICTIVE is a participatory design technique for increasing the direct and effective involvement of users and other stakeholders in the design of software. This paper reviews a year of the use of PICTVE on products and research prototypes at Bellcore. What we have learned is illustrated through five brief case studies. The paper concludes with a summary of our current PICTIVE practice, expressed as three developing, interrelated models: an object model, a process model, and a participation model.
