Usability Evaluation of Business Process Modelling Tools through Software Quality Metrics

Due to the widening range of functionality, the software is becoming more complex, and there are a number of problems related to its ease of use, and specifically, its usability. The concept of "usability" is associated with the ease, efficiency and satisfaction of using any item, including computer technology. Specialists in the development of user interfaces face the challenge of creating products based on user experience and combining aesthetics, functionality, ergonomics, the ability to quickly accomplish the tasks, while also having to comply with the constraints imposed by the specificity of the activity for which the software applications are intended. It can be said that business process modelling software is characterized by medium and even high complexity due to the many functionalities they offer. In this regard, the purpose of this paper is to propose and implement a method for evaluation the usability of this type of product based on software quality metrics. As a supporting method for conducting the evaluation procedure we used Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. We evaluated some business process modelling tools for approbating the suggested method.
