Successful interactive services are based on scenarios that go beyond just pushing new technology. The process to develop these scenarios needs to be imaginative and well out of the ordinary to generate interesting, innovative and surprising concepts. The concepts then need to be thoroughly reviewed from a multiplicity of perspectives. The reviewing process may be light at first, but must advance as the scenarios get refined. Our scenario & persona development workshops facilitate this creative and multi-disciplinary process, in order to produce scenarios and personas that successfully combine realism and adventurousness.
