An extension to iStar framework as alternative to support design decisions in the task analysis performed in the Human Computer Interaction Area (HCI)

Abstract

Introduction— The goal of this work is to present i* framework as alternative to support design decisions in the Human Computer Interaction Area (HCI), mainly, in the process of task analysis. We show i* framework a modeling language suitable for an early phase of software system modeling to understand the problem domain, also, that provides methods to represent tasks, as well as support design decisions the development that satisfies the process requirements from the beginning until the end. To achieve our goal, approaches addressed to analyze notations aimed at task analysis and their representation. Finally, we present suggestions for improvement in the i* framework through a proposed extension for refining task model, instantiating examples and justifying our proposal through peer review.
