Kommunikation med hjälp av mock-uper
In several cases, systems that have been developed have been very time
consuming and cost a lot of money, but they still do not fulfil the users
requirements and requests. To make new systems better, you have to find a way
to communicate that allows the developers to understand the needs of the user.
The aim for our thesis is to highlight the importance of communication in
system development. To investigate this we have choosen to do a study of the
real-estate system. The work methods that have been used include mock-ups and
informal conversations with the user, who is employed by the Church of Sweden
in Ronneby.
Intranät En kommunikationskanal för alla?
Intranet is today a common technical groupware to communicate in many
organisations. People can interact through the Intranet and communicate within
the organization and get relevant information according to their workplace. It
can be difficult to get everybody to use the Intranet as an information- and
communication tool. This causes problems when people want to reach out with
information. With these thoughts we entered our work at Luftfartsverket at
Arlanda airport.
Förbättringsarbete på monteringsbana
In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.
Pamiro
This report describes the work with creating a CMS (Content Manager System). A
CMS is a
web tool so you easy can publish materials on your web page. With a CM Scan you
can
without any knowledge of programming web pages create and maintain a web page.
This
will result in that you and your organisation save time and money. You can also
split the responsibility
for the webpage in different roles, but still keep the control.
We have chosen to create our CMS in a script language called php4 and with the
database
server MySQL, we have also used JavaScript a lot.

Användarinvolvering i ett systemutvecklingsprojekt -Är det effektivt?
In most software engineering project, users are only involved in the beginning
of the project as a help to design the requirements specification but users can
be involved after this phase too, but is it effective to do so?
With this report we would like to investigate how effective it is to involve
users after the requirements specification has been written and approved.
To find out how effective it is to involve the users we try some fast and
simple involvement techniques on a quite far gone project. These techniques
include ethnographic studies, prototypes and surveys. We also interviewed a
couple of people who work with usability and finally delivered a report with
our results to them to find out if they found our result relevant. By also
documenting how much time we spent involving users we will show to which degree
user involvement is effective.
We found out that a couple of fast techniques could get very much result in the
form of usability enhancing suggestions to the developers.

Små- och medelstora företags uppdateringsarbete av hemsidor
Många små- och medelstora företag har idag en hemsida. För att en hemsida skall
vara ett effektivt kommunikationsmedium med kunder krävs dock att den är
uppdaterad. Vi anser att många företag ej förutser vilka resurser som krävs för
att hålla sidan uppdaterad.
Vi vill därför kartlägga vilka problem företag i dagsläget upplever att de har
med sitt uppdateringsarbete. Vi vill därefter se om det finns en möjlig lösning
i verktyget Smelink WEB ifrån Smelink AB, som säger sig underlätta webbnärvaron
för denna typ av företag.
För att undersöka ovanstående frågeställning har vi valt att gå ut med en
enkätundersökning rörande hur uppdateringsarbetet går till i två grupper av
företag. Den ena företagsgruppen använder sig utav Smelinks verktyg och i den
andra företagsgruppen vet vi ej hur uppdateringsarbetet går till.
Då vi sammanställt resultatet kunde vi konstatera att det ej fanns några
omfattande problem rörande uppdateringsarbetet hos de företag som vi undersökt.
Kan Hedvig lösa De mystiska tecknen? : en studie av två biblioteksdataprogram för barn
This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..
Trouble Ticket "Kommunikationen gav oss vind i seglen"
Rapporten huvudsyfte är att beskriva hur vi genom användning av språk och
kommunikation har kunnat tillgodose våra användares krav på ett
ärendehanteringssystem, samt på vilket sätt vi har använt artefakter för att
kommunicera. Vi kommer att beskriva olika delar av projektet där språk och
kommunikation har haft centrala "roller" och visat sig ha olika betydelse
beroende på de personer som medverkar och i vilken miljö situationen har
utspelat sig. Rapporten behandlar även hur resultatet av ovanstående har lett
oss in i en utvecklingsprocess där vi försökt tillgodose användarens krav på
bästa sätt. Vi kommer också att beskriva de kända och tidigare okända metoder
som vi använt oss av för att uppnå vår målsättning, att överlämna en första
prototyp av ett ärendehanteringssystem..

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems.
The aim of this study is to:
? investigate the work pattern of the production managers when using the information system to plan the harvesting operation;
? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system;
? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern;
? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion.
The conclusions of the study were:
? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning;
? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information;
? the computer systems are however divided in many subsystems.

"Fenomenalt" eller "De borde kunna mer om datorer" : En undersökning om datorhjälpen på högskolebibliotek
"Outstanding" or "They ought to know more about computers" : A study on computer support at university libraries.The main purpose of this study is to investigate the support computer users are given at university libraries. Further, the aim is to find out if the users thought they received the support that they needed. The study is carried out at two different university libraries. The data is obtained through interviews with the librarians, observations of the daily work at the information counters and questionnaires handled out to the users.The study indicates that variables such as knowledge, time and equipment play a central role in making the computer support successive. To a great extent the computer support is synonymous with information search, but it also deals with word processing and technical support connected with computer errors.
