Med minskad komplexitet får ett system ökad användbarhet Fallstudie av användbarhet i ett affärssystem
One of our reasons is that we think the subject usability is interesting, is
that we think it is an important. Usability is maybe the most important element
when you develop or choose a system because it can save money for the companies
and give the users a more delightful and better work environment. The aim of
the investigation is to find out if the implementation of a web portal is a
direction to reach higher usability in a complex system that consists of
several different interacting applications.
The objective of our investigation is to show if the implementation of a web
portal is a direction to reach higher usability in a complex system that
consists of several different interacting applications. In our case we will try
to see if Karlshamns AB:s recently implemented web portal is more useful than
their previous application (Movex with interacting programs)
One thought with the report is to give the system developers a perspective of
how the usability can be in-house made applications versus standard
applications. Also companies that not have any computer- or department for
development and which are thinking of get hold of, change, replace or
complement their system and applications, may have some interest in our thesis.
We have used a qualitative investigation method in our study to answer our
hypothesis.
Bibliotekskatalogers användarvänlighet : en usabilitystudie av Umeå Universitetsbiblioteks katalog Album
The purpose of this thesis is to examine the usability of the Umeå University library catalogue Album. The aim is to evaluate the catalogue in order to establish if there are any problems that could be solved by modifying the catalogue. The following questions are answered: How should a good catalogue be designed? Which problems are common when using a library catalogue? Is Album user friendly? Are there any problems that occur when using Album and how can the catalogue be changed to avoid the problems? To answer these questions I have performed a usability test in which five persons, all students, got to carry out twenty tasks in the catalogue and talk about what they were doing and thinking while doing the test. This method is a usability method called Think Aloud.
En väg till förbättring : Systemanalys ur ett användarperspektiv
In almost every workplace today IT-systems have strong and significant roll in theeveryday work. It is therefore important that the systems have a good functionalityand that they work as an aid for the users. This thesis aims to study the systems atthe company Telge Nät and to analyse them from a usability perspective. By using thisperspective it has been obvious how difficult it is to make improvements on usability,once the system is in place. Even other larger improvements of the systems aredifficult to make at this stage and this is something that the users are aware of.
Smartphones, Användare och Estetik : En Användbarhetsstudie
The Ericsson R380 is a so-called smartphone, combining an advanced mobile phone with a Personal Digital Assistant (PDA). To evaluate the usability of the Ericsson R380 and benchmark it against the Nokia 9110 Communicator and the Motorola A6188 Accompli, a repeated measurements experiment was performed. 18 subjects (10 men and 8 women) with no previous experience of any of the interfaces participated. Half of the subjects had extensive experience from using Ericsson mobile phones and half of the subjects had extensive experience from using Nokia mobile phones. A set of 9 tasks to be solved on each interface was presented to the subjects.

Hur fungerar vårdens IT-system egentligen? : Jämförelse av elektroniska patientjournalsystem
To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.
?Nej, men jag söker väl tills jag hittar?: En studie av discoveryverktyget Summon utifrån ett användarperspektiv.

The study aims to answer the following research questions: How do the students execute search assignments in the Summon interface? How intuitive and easy to navigate is the system from a user perspective? What are the students? opinions about Summon, regarding usability?Five students with varying information seeking skills are asked to perform search assignments during controlled observation, followed by semi-structured interviews. Our findings are presented in the context of previous research and show correspondence with the results of related studies.
GRÄNSSNITTET OCH ANVÄNDARNA En undersökning av två gränssnitt mot en bibliotekskatalog.
The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..
Optimala antalet användare i en användbarhetsutvärdering : En undersökning om hur många användare som bör vara med i en användbarhetsutvärdering för att uppnå mättnad och ett gott resultat.
Syftet med den här uppsatsen var att belysa frågan om hur många användare det behövdes för att uppnå en viss mättnad i en användbarhetsutvärdering för en specifik flash-applikation kallad My Garden. De aspekter som låg till grund för denna uppsats var brytpunkten i ökningen av unika fynd i korrelation med höga procentsatser. Med hjälp av den formativa utvärderingen och analysen av denna gick det sedan att ta reda på vilka problem (så kallade fynd) som upplevdes av användarna i gränssnittet. Resultatet av analysen resulterade i 95 unika fynd i tio användbarhetsutvärderingar. Resultatet visade följaktligen att för denna sorts utvärdering behövdes sju användare för att uppnå 93 % av alla unika fynd som hittades och därmed uppnå en slags mättnad i avklingandet av hittade unika fynd..
Kundens kund : En studie i användarcentrerad systemutveckling och designmetoder
This thesis investigates how web agencys in Stockholm use, value and incoroprate the terms usability, user experience and interaction design in their work process. The purpose of this study is to investigate how creative professionals works with the notions of usability, user experience and interaction design with focus on the end user. Our definition of creative professionals is every employee at a web agency involved in the work process of developing digital artefacts in any capacity. We wanted to investigate how these notions are considered, consciously or unconsciously, during the workprocess. Semi-structured interviews were conducted at three different web agencys with eight different employees.
Förbättrad Kravhantering med hjälp av Lösningsinriktad Pedagogik
Abstract
The purpose of writing this thesis was to improve methods during requirements
engineering phase. Usercentred system engineering has some problem areas, which
are examined and verified to create a new guideline for developers. This
guideline tends to make requirements engineering more effective and help
developers create more concrete requirements.
It is not uncommon that system development projects ends up with unsatisfied
users or delay in deliveries. The reasons are different kinds of communication
problems between users and developers during verification of requirements.
There is a therapy model, called solution-focused therapy, used in family and

Livsstilsförändringar vid osteoartrit hos katt
Background: Osteoarthritis is understood to be a common cause of pain and dysfunction in cats; however there are few validated pain assessment methods for chronic pain in cats. In order to design a proper pain questionnaire, it usability need to be tested in both sound and sick cats.
Aim: The aim was to investigate the usability of the pain questionnaire ?Lifestyle changes in cats? by compiling the results from the pain questionnaire reflecting the lifestyle in 30 healthy cats and compare it to the results from a clinical examination, as well as proposing improvements and additions to the questionnaire based on a literature review.
Material and method: 30 healthy cats participated in the pilot study; the pet owner filled out a pain questionnaire with 16 questions regarding their cat´s behavioral and eventual changes in behavior and physical function. Thereafter the cat walked over a pressure measurement mat and finally underwent an orthopedic-directed clinical examination.
The literature was found on Web of Knowledge, PubMed, Sciencedirect, and Google Scholar and also with the help of my supervisors.
Marknadsinriktad Requirements Engineering : kännetecken och centrala aktiviteter
Denna rapport behandlar den marknadsinriktade Requirements Engineering (RE) processen. Allt fler företag väljer idag att implementera standardsystem i sina verksamheter. Den situation som ett standardsystem utvecklas i är annorlunda jämfört med den som ett kundspecifikt system utvecklas i. Detta innebär att den traditionella RE-processen inte är anpassad till dessa nya förhållanden.Syftet med denna rapport är därför att utreda vad som kännetecknar en marknadsinriktad RE-process som stödjer kravhanteringsarbetet vid utvecklingen av ett standardsystem. Rapporten avser även att undersöka hur RE tillämpas av marknadsinriktade systemtillverkare i praktiken.
