In the Information and Communications Technology era, eGovernment projects present a great opportunity for governments to offer better and quicker services to their users from the public. However, the success and the failure of these projects to achieve the expected goals depend heavily on some important aspects, mainly websites usability. The research in this thesis focuses on the usability of eGovernment websites in Jordan as a case study, as it is one of the developing countries facing problems due to websites usability. Hence, the main aim of the research was to investigate the situation of the Jordanian eGovernment websites with a view to improving usability, as well as to propose a roadmap to reinforce websites usability in order to achieve better utilisation and a more successful eGovernment project in Jordan. This research work achievement and major contributions have been accomplished through three stages; the first stage investigated the level of usability of eGovernment in Jordan from a manager‟s perspective. The study for this stage involved a sample of 37 managers who are in charge of managing and maintaining eGovernment projects in Jordan. The research revealed that the main problems undermining Jordanian eGovernment usability are the lack of the general usability awareness amongst management, the lack of clear usability standards and guidelines, the insufficient level of end-user involvement in the process of design and maintenance of eGovernment services, limited budgets and the lack of expert web-designers. The second stage was to build a clear overview about the status of eGovernment websites usability in Jordan by investigating main aspects related to design that affect the success of eGovernment websites in Jordan from an end-user‟s perspective. The study for this stage involved 155 participants for testing five Jordanian eGovernment websites. It was revealed that the Jordanian eGovernment websites generally do not have a high level of usability, and that there is a lack of understanding of the needs and requirements of the end-users. In addition, the study discovered a lack of testing and monitoring of the websites, a lack of involvement of end-users, poor collaboration and coordination among government agencies, poor standardisation, and lack of trust/satisfaction. The outcome from the early mentioned studies was used in the third stage, which has been used to establish the model to improve the usability of eGovernment websites in Jordan through a clear roadmap. The model has four components: website manager and designer, end-users, usability committee (advisory, executive), design process (usability requirements, pre-implementation test, post-implementation and maintenance). The model which was established and evaluated can be very beneficial for promoting eGovernment websites usability, in Jordan particularly and in other countries with similar backgrounds and situations.

The aim of the thesis is to evaluate the current version of the Integrated Study Information System at the University of Economics with focus on usability. An improved solution is suggested based on latest development in the field. The theoretical part contains selected approaches to redesign of web application. The resulting solution is in a form of redesigned key parts of the information system common to most functions in the student related section. Wireframes and static website mockups are used in order to illustrate the suggested solutions.

No desenvolvimento de produtos de consumo tem sido relevante a aplicação de conceitos de usabilidade. Tais conceitos permitem o desenvolvimento de produtos que se caracterizam pela facilidade de aprendizagem de uso e quase total inexistência de erros na utilização. Em 2006 foram publicadas as duas primeiras partes da norma ISO 20282. No presente trabalho, são apresentados os aspectos mais importantes da norma com alguns exemplos que visam esclarecer alguns destes aspectos; a continuação à norma é aplicada mediante a realização de testes de usabilidade na avaliação da facilidade de operação de produtos de consumo. Sendo assim, o objetivo desta parte é analisar a utilidade da norma e poder detectar seus pontos altos e fracos. / The application of concepts of usability has been relevant in the development of consumer products. Such concepts allow the development of products known for its simple learning of operation techniques and almost non-existing errors in its use. In 2006 the first two parts of ISO 20282 standard were published. Here, the most important aspects of this standard are introduced giving some examples to clear some issues. The standard is applied through the use of tests evaluating the ease of the operation of consumer products. The objective of this part of the norm is to analyze its usefulness and be able to detect its strong and weak points.

It is in society's interest that news is conveyed in a correct and memorable manner. News contributes to general knowledge and increases awareness of other people's life situations. Because of news the population is able to follow and be a part of the political debate. Therefore, it is important that one remembers what one has seen, both in long and in short term, i.e. memorability is a critical aspect when it comes to news. The aim of this work was to study the news form a memorability perspective, that is, how long one remembers the news after watching them. Also, aspects such as length and complexity of news reports were studied. The results show that the percentage of memorability steadily decreases over time. The test was conducted under a period of four days. The results also suggests that it is easier to remember short news reports rather than long news reports and soft news rather than hard news.

The importance in finding components that may result in won market advantages for an organization has increased in the latest decade, as a result of the increasing competition across a range of industries. One factor that has been shown leading to efficient products and benefits in terms of time- and resource savings has been an implementation of user experience interaction guidelines, UXIG. These are guidelines with the purpose to improve the products within an organization out of a holistic perspective and increase the interaction between the product and its user, in a positive way. This study has been conducted at GE Healthcare Life Sciences, in Uppsala, focusing at chromatography. The purpose of this study was to investigate how to create and implement UXIG at this, large, international organization – with a heterogeneous product portfolio. In order to come up with recommendations in these questions a benchmarking study, interviews and a questionnaire was made. The purpose with the interviews and questionnaire was to find out how other organizations and their employers had been acting and thinking when reasoning about these questions whereas the benchmarking study consisted of a comparison of famous UXIGs. The result of this study shows that e.g. preparation, an overall clarity from the creators/management, a strong communication channel between the management, creators of the UXIG, its users and the users of the systems, how they are matching to the organization, their availability and structure, are important components in order to create/ develop UXIG in a successful way.

People are living increasingly large swaths of their lives through their online accounts. These accounts are brimming with sensitive data, and they are often protected only by a text password. Attackers can break into service providers and steal the hashed password files that store users’ passwords. This lets attackers make a large number of guesses to crack users’ passwords. The stronger a password is, the more difficult it is for an attacker to guess. Many service providers have implemented password-composition policies. These policies constrain or restrict passwords in order to prevent users from creating easily guessed passwords. Too lenient a policy may permit easily cracked passwords, and too strict a policy may encumber users. The ideal password-composition policy balances security and usability. Prior to the work in this thesis, many password-composition policies were based on heuristics and speculation, rather than scientific analysis. Passwords research often examined passwords constructed under a single uniform policy, or constructed under unknown policies. In this thesis, I contrast the strength and usability of passwords created under different policies. I do this through online, crowdsourced human-subjects studies with randomized, controlled password-composition policies. This result is a scientific comparison of how different password-composition policies affect both password strength and usability. I studied a range of policies, including those similar to policies found in the wild, policies that trade usability for security by requiring longer passwords, and policies in which passwords are system-assigned with known security. One contribution of this thesis is a tested methodology for collecting passwords under different policies. Another contribution is the comparison between password policies. I find that some password-composition policies make more favorable tradeoffs between security and usability, allowing evidence-based recommendations for service providers. I also offer insights for researchers interested in conducting larger-scale online studies, having collected data from tens of thousands of participants.

Medius is a software company which provides IT-solutions that streamlines and automates business processes. The purpose with this thesis was to investigate the possibility to integrate usability evaluation in the development process of Medius software MediusFlow. How such integration would be done, and which usability evaluation methods could be used. To be able to provide a suggestion, a prestudy was conducted, this in order to get a good overview of Medius as a company as well as the development process of MediusFlow. With the prestudy as a basis, the main study was conducted, and four different usability evaluation methods were chosen. In this study, the four chosen methods were Cognitive Walkthrough, Coaching Method, Consistency Inspection and Question-Asking protocol. These usability evaluation methods were carried out, evaluated and analyzed.  Based on the studies and the literature, a suggestion regarding integration of usability evaluations was made.  The result from this case study was presented as a process chart, where the different phases in Medius software development process are matched together with suiting usability evaluation methods. The relevant phases and their suggested methods: Preparation phase - Cognitive Walkthrough and Coaching Method in combination with Thinking-Aloud and Interviews Hardening phase - Coaching Method in combination with Thinking-Aloud and Interviews, as well as Consistency Inspection Maintenance - Field observation This result is a part of the overall work towards a more user-centered design of the software.
