Abstract
Usability is widely used in software engineering as a criterion of product quality and acceptance. Studies revealed that one dollar investment in usability brings 10 times more profit than investments in advertising. Usability of web-sites and desktop applications has been extensively investigated during last decades. However, little was done in the area of usability of process modelling tools. We argue that generic usability measurement frameworks do not reflect the particularities of this kind of applications. In our work in progress paper we are conducting a number of empirical studies in order to find out environment dimensions and their effect on usability attributes. As a result we propose a theoretical usability measurement framework which underlying hypotheses have to be evaluated in future research.
