Abstract
The growth of the Internet and related technologies has enabled the development of a new breed of dynamic websites and applications that are growing rapidly in use and that have had a great impact on many businesses. These websites need to be continuously evaluated and monitored to measure their efficiency and effectiveness, to assess user satisfaction, and ultimately to improve their quality. The lack of an adaptive usability evaluation checklist for improvement of the usability assessment process for social network sites (SNSs) represents a missing piece in usability testing. This paper presents an adaptive Domain Specific Inspection (DSI) checklist as a tool for evaluating the usability of SNSs. The results show that the adaptive social network usability checklist helped evaluators to facilitate the evaluation process, and it helped website owners to choose the specific-context usability areas that they feel are important to their usability evaluations. Moreover, it was more efficient and effective than user testing and heuristics evaluation methods.
Highlights
It is clear that Heuristic Evaluation (HE) and User Testing (UT) are the most important traditional usability evaluation methods for ensuring system quality and usability [1; 2]
Complex computer systems, mobile devices and their applications have made usability evaluation methods more critical; usability differs from one product to another depending on product characteristics
It allows anyone to adopt any area of usability or any principle to determine the usability problems related to the seven specific areas in social network sites
Summary
It is clear that Heuristic Evaluation (HE) and User Testing (UT) are the most important traditional usability evaluation methods for ensuring system quality and usability [1; 2]. Companies, educational systems and governments adopt SNSs tools to their environment work to save time, make money and to improve their corporate productivity In this regards, designing interactive websites and evaluating them are common stages of product development. The current traditional usability methods to measure quality attributes, such as, effectiveness, efficiency and satisfaction are not adequate for the new contexts of use, and are not stable in the modern dynamic environment such as SNSs and e-catalogs systems [19; 20]. Having extensively reviewed the existing literature on web usability evaluation methods; this research is unique in systematically constructing an adaptive framework that is applicable across numerous domains This DSI framework generates DSI checklist as available tool for assessing and improving the usability of a product
