User-Centered Design and Business Process Modeling: Cross Road in Rapid Prototyping Tools

Fast production of a solution is a necessity in the world of competitive IT consulting business today. In engagements where early user interface design mock-ups are needed to visualize proposed business processes, the need to quickly create UI becomes prominent very early in the process. Our work aims to speed up the UI design process, enabling rapid creation of lowfidelity UI design with traditional user-centered design thinking but different tooling concepts. This paper explains the approach and the rationale behind our model and tools. One key focal point is in leveraging business process models as a starting point of the UI design process. The other focal point is on using a model-driven approach with designer-centered tools to eliminate some design overheads, to help manage a large design space, and to cope with changes in requirements. We used examples from a real business engagement to derive and strengthen this work.
