The purpose of this study was to create a web application that provided peer to peer rental solutions for students and while doing so maximize the usability of the application with regards to simplicity and online trust. An initial market survey was conducted, see appendix B, and the overall results were promising. The few survey takers that were hesitant towards the idea thought that using a rental solution would not be worth the while. Hence the research question focused on maximizing usability in regards to simplicity and online trust in order to make the e-shop an easy rental solution to use. The application was developed in three iterations and through the development process user tests were conducted and metrics regarding simplicity and perceived online trust were collected. The test conducted made use of the concurrent think aloud procedure, retrospective probing, surveying and time data used for calculating the effectiveness and efficiency of the test participants. The test results all improved throughout the development process and the application was perceived as both simple and trustworthy by test participants. By the end of the study, an application that could provide a peer to peer rental solution that was trusted by its users and was simple to use was realized. The study concluded that the evaluation methods used were good indicators of whether a web application is simple and trustworthy by identifying issues with the application as well as the improvements reflected in the test results. However they should have been applied on separate test occasions.
