We looked for commonalities and similarities to further group the defects within each category as well as across categories. At the same time, we also used the card-sorting technique to group defects that could not be classified using UPT. : We used Usability Problem Taxonomy (UPT) to classify 377 usability defect reports from Mozilla Thunderbird, Firefox for Android, and the Eclipse Platform. : To address this gap, as part of our wider usability defect reporting research, we have developed a new usability defect taxonomy specifically designed for use on OSS projects. This includes incomplete coverage of usability defect problems, unclear criticality of defects, lack of formal usability training of most OSS defect reporters and developers, and inconsistent terminology and descriptions.

However, existing usability defect classification taxonomies have several limitations when used for open source software (OSS) development. Accurately classifying these reported usability defects is critical for reporting, understanding, triaging, prioritizing and ultimately fixing such defects. : Reporting usability defects is a critical part of improving software. This proves that WebQEM method for optimization of monitoring social media and online media application can improve the software quality. Second global evaluation gives a value of 77,41%, from the improvement in first global evaluation. After evaluation, an improvement is applied to the application according to the criteria from the result of first global evaluation. First global evaluation of monitoring social media and online media application gives a score of 70,44%. There are two kinds of evaluations: basic evaluation and global evaluation.

In this paper, WebQEM is used in optimization for web application. Based on this case, a software quality testing is needed so a software can be said worthy and qualified to use, not just limited to mere testing, but also for optimizing the software to create a well maintained application in accordance with software development life cycle. In this research the application that used is social and online media monitoring at PT.

Human becomes dependent on variety of applications, ranging from small scale application for entertaining user to large scale web application for one or multiple businesses work. Along with the rapid growing world of technology nowadays, application becomes an important requirement for every human in person.
