This study is about the selection of test groups for a user test. The natural choice for company is to choose people that are included in the target group for the product or system that are about to be tested. This is something I have chosen to focus on. Is there reason to believe that you would choose people to your test group that are not part of the target audience and still produce an equally good result? To learn more about this, a test is conducted on a product that has one focus area and a clear target audience, in this case Snapchat. This research is showing that it’s a difference depending on what people are picked for the test. The two different groups focused on different things in the test that gave different goals to follow.

Viva la Diva är ett Svenskt makeup-varumärke som nyligen har lanserat sin nya webbplats. Denna webbplats har inte blivit testad på deras slutanvändare eller målgrupp. Genom att använda en heuristisk utvärdering och 12 Think aloud-tester har flera användbarhetsproblem upptäckts där designen behöver förbättringar. Senare i rapporten presenteras några förbättringsförslag om hur användarupplevelsen kan förbättras på webbplatsen, men också hur problemen som jag fann under utvärderingen och Think aloud-testerna kan lösas. Jag tillhandahåller också för Viva la Diva ett designförslag för en av deras sidor som inte är helt färdig i designen. Detta arbete ger insikt i hur man kan använda en heuristisk utvärdering och Think aloudtester för att upptäcka användbarhetsproblem på webbplatser. / Viva la Diva is a Swedish makeup-brand that has recently launched their new website. This website has not been tested with their end-users or target users. By using a heuristic evaluation and 12 Think aloud-tests several user problems have been discovered where the design needs improvements. Later in the article I present some suggestions on how to improve the user experience on the website, as well as fix the problems that I found during the evaluation and Think aloud-tests. I also provide Viva la Diva with a design suggestion for one of their pages that is not completely finished in the design. This work provides insights on how to use a heuristic evaluation and Think aloud-tests to discover usability problems on websites.
