Choosing the Right Task Modelling Notation: A Taxonomy
The Handbook of Task Analysis for Human-Computer Interaction, Lawrence Erlbaum Associates, (2004)
Abstract
A number of task modelling notations have been developed in the Human-Computer Interaction (HCI) communities, often with different goals and thus different strengths. Usually, each model is designed to be employed at a specific phase of the Software Development Life Cycle (SDLC). Without an explicit understanding of the different attributes of these models, it is difficult to select a specific one to achieve one's goals. To address this issue, we propose a taxonomy consisting of several axes. The elements of the taxonomy have been defined according to various criteria we have found useful to consider when having to decide on a specific methodology or task model. In this chapter, we first present our taxonomy. We then illustrate it with a few examples. We choose these models either because we used them ourselves, or because they are the most popular in the literature.
