Justification of Evaluation Approach (user testing) User testing, this is the process whereby users carry out the intended task efficiently (time), effectively (number of errors and completion rate) and satisfactory. It can either remotely, in the lab and automated. User testing has always been a great way of improving and optimizing user’s experience and increase business performance. The user testing is always needed, to check if the user interface is easy to understand, use and find the site level problems. It is important to capitalize on people’s increasing propensity to make purchase and order online by offering the best online user experience possible and by doing so it encourage repeat visits of site. And it is best to run specialized user testing on important pages so as to know the page usability problem. E.g. pages like registration pages, and also pages where users buy products and make payment. The possible attendances of user testing are: * Representative user * Test host * At least one developer * At least one business representative. In a recent study (Jakob Nielsen 1998), gave two test coverage on the usability testing problems: (1) site level usability which involve (home page, information architecture, navigation and search, linking strategy, internally vs. externally focused design, overall writing style, page templates, layout and site-wide design standards, graphical language and commonly used icon. (2) page-level usability: - specific issues related to the individual pages, understandability of headlines, links and explanations, intuitiveness of forms and error messages, inclusion or exclusion of specific information, individual graphics and icons. User testing issues required in term of cost, this will depend on the size of the website, the number of times you
