In this chapter it will be evaluated whether incrementalism can account for Geographical Information Systems not reaching its full potential, and the expectations made in the hype, in the field of policy design. This will be done by first elaborating on Geographical Information Systems, what they are, what the expectations at the beginning of the hype were and what the actual use is. Next the rational actor model, bounded rationality and incrementalism will be elaborated on. Two case studies in which Geographical Information Systems were used to enhance policy making will be demonstrated and used to draw final conclusions on which part of the potential of Geographical Information Systems has not been reached and how the expectations during the hype could not meet practice and how this can be explained.
