This Master's Thesis addresses the topic of usability testing of web-based systems. It reviews existing testing methodologies and recommends a collection of test tools and approaches suitable for usability testing. This thesis introduces a new methodology called Tabie for scoring web system under test. The methodology combines both the ease of use of the user interface (syntactic testing) as as well as its content (semantical testing). This approach is well suited for workflows in marketing agencies where content tweaks and its evaluation is done on an ongoing basis in order to attract more viewers and potential customers. The Tabie methodology provides a quantitative and repeatable process, automating the tweak-evaluate iteration.

In the last few years there has been a great development of e-shops and their usage. More and more customers are searching for the opportunity to buy products and services through the internet shops. This is related to the fact that more and more emphasis is placed on their applicability. This thesis deals with the quality of the site and the needs of the application and descibes the use of interactive elements. All the mentioned options are applied in this thesis and compared to the specific e-shop. As a part of the user usability testing there is also a suggestion for corrective actions of discovered deficiencies.

This study was conducted to explore the design of an application in the collaborative consumption area. To explore this, different factors that motivate users to participate in collaborative consumption were investigated. From these factors, User Experience (UX)-attributes were generated as a starting point for the researcher to create concepts and design a digital prototype. The usability of the prototype and whether the UX-attributes had been achieved were later evaluated. On the basis of the usability and interview results, the intent to use the application was explored. Five participants took part in the usability test. This test included measuring task success, user expectation measure and a SUS-questionnaire, after which an interview was conducted to explore the achievement of these attributes. The interviews were analyzed using the thematic analysis method, and the results showed that the UX-attributes that were chosen were sufficient in generating a concept for collaborative  consumption that could communicate these important factors. The results from the usability tests show that the design has well above acceptable usability, and although the interview results show that the UX-attributes were fulfilled in varying degrees, they were all fulfilled. Furthermore, by examining the usability and interview results an intent to use the application was discovered.

The purpose of this thesis is to demonstrate the evolution of product semantics and its options in interactive system's design. This paper focuses on characteristics the emerge of product semantics and areas from which it derives. It also describes current methods of testing usability of interfaces that are optimalized by product semantics. Analyticcal part consists from interface analysis, testing using knowledge from product semantics and evaluation. Conclusion of this thesis is devoted to a concept proposal of design methodology using the knowledge from product semantics.

Context. During each iteration of the application, we need to test the usability of the application. Therefore, how to improve efficiency and test according to the user's real experience is a problem faced by the company. According to our preliminary research on the literature. In the past, the usability of software systems was evaluated subjectively and the process was not well defined [21]. Every usability evaluation method has its advantages and disadvantages. Some are difficult to apply, and others are dependent on the measurer's opinions or instruments [21]. Moreover, currently, there are few studies on usability testing for e-commerce applications. And there is a lack of a usability test optimization scheme suitable for e-commerce applications. Therefore, we choose this direction for research. Objectives. This paper aims to provide an optimization method for usability testing process based on user requirements for e-commerce applications existing in the market, so that enterprises can more effectively implement the usability testing process in the process of iterative update of applications. Methods. In order to find the answers to the research questions, we used Literature review and Survey to collect the data. In the Survey section, we used the Questionnaire and Interview methods. After the data collection is completed, we perform quantitative and qualitative analysis of the data and organize the research conclusions. Results. Through a literature review, we conducted a systematic review of the usability challenges in e-commerce applications and how to overcome them. And we found the research direction in this process. We use the questionnaire to obtain the usability requirements of respondents (also users of e-commerce applications) for e-commerce applications, and use our optimization method (EEC) to translate user's requirements into usability test script content. And according to the feedback of the respondents to determine the content priority. We used interviews to understand the priorities that companies follow when actually performing usability testing. And compare it with the priority of our script to verify the effectiveness of our method. Conclusions. We summarize relevant conclusions by finding answers to research questions. Finally, an optimization method for usability testing is summarized, which will help future testers better implement usability testing to a certain extent.

As the digitisation of healthcare progresses, there are still problems in terms of usability. With the goal of exploring solutions to these, an email inspired design for an electronic health record system was implemented using modern web technologies. The implementation was then evaluated in a series of usability tests conducted with five orthopaedic surgeons. Participants were asked to perform small tasks on a mocked data set, and the sessions were concluded with debriefing interviews. The focus was on the areas that are new in this design. The results suggest that the general design works, and no critical flaws were identified at this stage. Most of the issues that were found are likely to be solved with more training and experience, but there is still room for improvement. Participants had positive reactions overall, and plenty of feedback was collected regarding areas of improvement and feature suggestions. Due to the limitations of the test, the findings mostly relate to the intuitiveness of the design. To draw stronger conclusions regarding the viability of the design in a real environment, further testing with more data, realistic test tasks and more prerequisite training is necessary. / Digitiseringen inom sjukvården ökar, men det finns fortfarande problem när det kommer till användbarheten av de digitala system som finns på marknaden. Med målet att utforska lösningar på dessa problem implementerades i detta arbete en e-post-inspirerad gränssnittsdesign för ett digitalt journalsystem med hjälp av moderna webb-teknologier. Implementationen utvärderades genom användartester där fem ortopediska kirurger deltog. Deltagarna ombads använda gränssnittet för att utföra små testuppgifter med påhittad patientdata, och sessionerna avslutades med intervjufrågor. Fokuset var på de delar som är nya i den här designen jämfört med redan existerande system. Resultatet visar att det generella upplägget fungerar, och inga kritiska brister upptäcktes i detta stadie. De flesta av problemen som uppdagades kan troligen lösas genom att användarna ges möjlighet till mer träning och får mer erfarenhet, men det finns fortfarande förbättringutrymme. Deltagarna hade positiva reaktioner i allmänhet, och många förslag kring förbättringsområden och önskemål kring utökad funktionalitet samlades upp. På grund av användartestets begränsningar belyser resultaten i detta test mest vilka delar av gränssnittet som är intuitiva eller ej, medan det som är mer intressant för den här typen av dagligen använda system egentligen är huruvida de är effektiva att använda i det dagliga arbetet. För att kunna dra säkrare slutsatser kring om den här designen skulle fungera i riktiga arbetssituationer behövs mer testning med större mängder patientdata, mer realistiska testuppgifter och mer tid för deltagarna att lära sig systemet i förväg.

Hantering av nätverk är en utmaning för dagens företag.Nätverkshanteringssystem är ofta komplexa och felbenägna, vilket gör demtröttsamma och svåra att arbeta med för nätverksansvariga. Tidigare forskningvisar att dessa system oftast inte är särskilt användbara, med den förmodadeanledningen att mer fokus läggs på funktionalitet än användbarhet då säkerhetär en så viktig del av nätverkshantering. Dock kommer ett system som inte byggsefter användbarhets- och user experience-kriterier att generera fel även omfunktionaliteten är korrekt byggd. Tidigare forskning visar också att det finns enavsaknad av effektiva användbarhetstester specifikt för nätverkshantering.I den här studien skapas ett set heuristiker (riktlinjer för användbarhet),skräddarsytt för nätverkshantering. Dessa heuristiker kan sedan användas ianvändbarhetstester för nätverkshanteringssystem. Studien är genomförd isamarbete med Axis Communications AB. Deras nätverkshanteringssystem”Music” används som en hjälp för att hitta och validera lämpliga heuristiker, ochheuristikerna används också för att testa Musics användbarhet. En systematisklitteraturstudie och användarintervjuer på Axis används för att upptäcka viktigaaspekter inom nätverkshantering. Setet med heuristiker skapas sedan genomatt sätta upp ett start-set med klassiska heuristiker och modifiera dessa utifrånde tidigare upptäckta viktiga aspekterna. Heuristikerna valideras sedan genomatt använda dem i användbarhetstester av Music. Valideringen visar att de nyaheuristikerna är mer effektiva vad gäller att hitta problem i ettnätverkshanteringssystem än ett klassiskt set av användbarhets-heuristiker(Nielsens heuristiker). Utöver setet med heuristiker resulterar studien också irekommendationer på förbättringar av Musics användbarhet, mock-ups med ettnytt designförslag för Musics GUI och generella rekommendationer för företagmed nätverkshanteringssystem. / Network management is a challenge for today’s enterprises. Networkmanagement systems are usually complex and error prone, making themtedious and difficult to work with for network managers. Related work show thatthese systems are often not very usable, the reason probably being that morefocus is put on functionality rather than usability since security is a veryimportant aspect of network management. However, a system not builtaccording to usability and user experience guidelines will generate errors eventhough the functionality is correctly built. Related work also show that there isa lack of efficient usability testing methods specifically for network management.In this study, a set of heuristics (usability guidelines), tailor-made for networkmanagement, is being created. These heuristics can then be used in usabilitytesting of network management systems. The study is conducted incollaboration with Axis Communications AB. Their network management system“Music” is used as a help in finding and validating appropriate heuristics, andthe heuristics are also used for testing the usability of Music. A systematicliterature review and user interviews at Axis are used to learn important aspectsof network management systems. The heuristic set is then created by setting upa starting set of classical heuristics and modifying it according to previouslyfound network management aspects. These heuristics are then validated byusing them in usability tests of Music. The validation proves the new set ofheuristics to be more effective in finding issues for a network managementsystem than a classical set of usability heuristics (namely Nielsen’s heuristics).Besides the set of heuristics, the study also results in recommendations ofimprovements on the usability of Music, mock-ups proposing a new design forMusic’s GUI and general recommendations for enterprises with networkmanagement systems.

Achieving the feeling of a personal connection over the internet is difficult but at the same time more relevant than ever with the world moving more and more towards digital meetings and online events. This study investigates how an exhibition area at an online conference could be created to provide a good user experience as well as provide value for the exhibitors at the conference. The study was performed through interviews, three stages of prototyping as well as usability testing of these prototypes to gather data and feedback on what could be done to achieve this goal. Through the principles of social presence, human centered, and user centered design, a prototype of how such a solution could look was developed. As a result, the test users felt that they would feel welcome in the digital booth and that they felt a greater incentive to join conversations with the exhibitors. On the other end, the exhibitors also felt like this solution would provide value in the form of monitorable gathered data that could be followed up on to investigate the value that the conference has given them. This concludes that engaging and valuable online exhibitions can be created as long as careful thought is put into designing them with the user and human in mind.
