Capturing visions and goals to inform communication design
Davide Bolchini, Giovanni Randazzo · 2005
Current requirements analysis methodologies for web applications fail to capture important elements of the requirements picture. On the one hand, there is the need for modelling the assumptions of a stakeholder which dictate her weltanschauung on the design (we call these visions). From properly eliciting stakeholder visions, important goals and requirements for the design may arise. On the other hand, we also need to better understand the emotional, psychological, social or individual elements which can trigger a person to use an interactive application (we call these motivations). User motivations - properly combined with stakeholder visions - are key to derive a sound set of user requirements. This paper extends existing achievements in goal-based requirements analysis for communication-intensive web applications by introducing the concepts of vision and user motivation. These new elements provide web analysts and designers with a methodological support to interpret and carry out requirements analysis in complex situations. A case study excerpted from a real web design project is used to show possible uses of the concepts discussed.
