Over the years the environment of many enterprises has become progressively more unpredictable and complex. In particular, the increasingly rapid development of technology with its dramatic impacts on the market significantly contributes to enhance environmental unpredictability. The enterprise needs therefore some tools which help them to monitor their environment and keep track of the market and technology evolution. Technology roadmaps present suitable characteristics for guiding the environment scanning and intelligence efforts of the enterprise, by simultaneously showing the possible evolution of technology, products and markets and explicitly considering their linkages. However, the standard implementation of technology roadmaps overlooks an essential factor which is often determinant in shaping the environmental conditions and evolution: the actors inside the system can indeed influence their environment, at least to a certain extent, through their action. Consequently, we propose to extend the standard technology roadmaps by include an actors layer which bridges the technology and product perspectives.
