Viewpoint modelling with emotions: a case study

In modern software development, considering the viewpoints of stakeholders is an important step in building the right system. Over the past decade, several authors have proposed solutions to capture and model these viewpoints. While these solutions have been successful, one viewpoint they have largely ignored is the emotional viewpoint of stakeholders. Considering the emotional needs of stakeholders is important, because users' perceptions of a product are influenced by emotion as much as cognition. Building on their recent work in modelling the emotional goals of stakeholders, the authors extend an existing viewpoint framework to capture emotional viewpoints, and to carry these from early-phase requirements to detailed software design. They demonstrate this with a case study of an emergency alarm system for older people, presenting the entire suite of models for this case study.
