Email: ashishkhanna@mait.ac.in Abstract- Usability of software systems have recently become a very significant quality factor for enhancing the quality of software and is usually associated with easiness in use and learn. A various usability models and ISO/IEEE standards have been proposed in literature with their own set of features and attributes. The proposed models are validated using a number of qualitative usability evaluation techniques. However, there is a lack of a commonly used, standard dataset for usability evaluation. In this work, two new datasets i.e. software development lifecycle (SDLC) and Live Auction are created and made publicly available. Moreover, in this paper, we have also done a critical analysis of usability evaluation techniques and use questionnaire evaluation technique to create the new datasets. Keywords: software usability, evaluation techniques, questionnaire, dataset, SDLC, live auction. 1. INTRODUCTION The demand for the quality of software systems is increased exponentially in recent years. Software usability has been an essential quality factor, and the literature review shows that the usability study for a software process can predict the success or failure of any software product. Usability [5] is an extent of which a software product can be used to achieve some specified goals with effectiveness, efficiency, and satisfaction.” Usability Engineering(UE) can be defined as “the systematic approach to improving the usability of user interfaces by applying a set of proven methods throughout the system development lifecycle” [14]. A number of intermediate levels are executed repeatedly according to the active user participation in developing a software product using UE model. Majorly, the usability estimation plays a major role in the Evaluation level of UE as the level has been executed by evaluation team, who is in charge of assessing the results which are obtained by applying usability International Journal of Pure and Applied Mathematics Volume 117 No. 15 2017, 1001-1014 ISSN: 1311-8080 (printed version); ISSN: 1314-3395 (on-line version) url: http://www.ijpam.eu Special Issue ijpam.eu 1001
