An integration of scenarios with their purposes in task modeling
Hermann Kaindl · 1995
Requirements capture and task modeling are very important but insufficiently supported parts of interaction design.In particular, promising approaches using scenarios have been proposed, but these are often viewed in isolation.We complement scenarios with their purposes, and explicitly represent and use relationships between them in task modeling.More precisely, we link scenarios (viewed as behavioral requirements) with functional requirements that describe the purposes of the scenarios.In addition, these scenarios can have functions attached that are required to make the desired behavior happen.We have applied our approach in realworld projects, and our experience suggests the usefulness of this approach.Essentially, it helps to achieve a more complete and consistent definition of the requirements and the task model.
