A Bottom up Approach for Synchronous User Interaction Design and Workflow Modelling

Traditionally, both interaction design and workflow modelling have been developed in a top down approach. The user interaction design process consist of several phases of user requirement engineering involving interviews, observations, etc. Likewise, workflow modelling traditionally involves a systematic process of requirement collection. In this paper we introduce a new approach where user interaction design is used in a systematic way to develop workflow models in an iterative bottom up approach. The methodology is illustrated by a practical case study of software development, supporting a blood transfusion workflow in a hospital.
