The development method «User-Centered Design» uses visualisation to record requirements. From the very beginning, the main use cases and processes are shown in form of detailed screens of the graphical user interface. From experience, visualisation is the best means for users, decision makers and implementers to review the concept in respect to its completeness, usefulness, usability and acceptance as well as its technical feasibility.
User-Centered Design thus leads to clearly better specifications and less change requests during implementation. Further advantages are a high user acceptance and a future-proof front-end information architecture. Particularly in complex projects, visualisation also helps to focus on the essentials and to avoid describing irrelevant or useless requirements. Based on examples from our experience with complex web and business software projects, we show the concrete practice of the method and discuss its opportunities and risks.
