Abstract [en]

A common problem with implementation of new communications hardware is that it is difficult to predict their effects on the information flow in an organisation. This leads to hardware investments, which are at best based on qualified guesses that they will improve the situation, and at worst based on half-pronounced promises from the local computer salesman. To help this problem it would be desirable to be able to simulate the information flow in an organisation in such a way that the effects of new hardware implementations could be studied. As the information flow in an organisation can be said to be a complex system, a Cellular Automata (CA) approach is appropriate to build such a simulation. CA approaches have been used for several simulations of complex situations before, as an example, models of combat (Dockery, and Woodcock, 1993) and models of traffic flow (Wahle, et al, 1999). In order to create a simulation, behaviour and information flows must be analysed and formalised using a computer-parsable notation language.

Abstract [en]

All organizations have an information system. An information system is all that which contribute to the distribution within an organization, and without the information system, the organization would not survive. Despite this, work with changing or constructing information systems often end up with suboptimal results. In recent scientific articles, and within profession-specific newspapers, the figures on how many such project end up as failures range between 70 and 80 percent. One source of problems with information systems work is deficiencies of the governance of the change processes. Further, many methods applied to information systems work are in fact software systems method and may thus be suspected to miss important aspects of the information system. In this thesis I have studied approaches for supporting the information systems development process. These approaches have all included trying to find aspects of the information system and trying to measure, simulate or in other ways asses them in order to get an overview of where effort has to be added in the development process.The results of the thesis include recommendations surrounding the simulations of such aspects, as well as a model where the aspects have been formulated into criteria for information system evaluation. The CISE model (Criteria for Information Systems Evaluation) is the main product, and it is available to useas a checklist during information systems work.

Abstract [sv]

Alla organisationer har ett informationssystem. Ett informationsystem är allt det som inom en organisation bidrar till att sprida information, och utaninformationssystemet skull organisationen inte överleva. Trots detta resulterar arbete med att ändra och bygga informationssystem ofta i resultat som är sämre än önskvärda. I senare vetenskapliga artiklar, och inom den professionella pressen, nämns ofta siffror kring 70-80 procent i samband med hur ofta dessa projekt misslyckas.En källa till problem med informationssystemsarbete är brister i styrningen av förändringsprocesserna. Vidare, många metoder som används för informationssystemsarbete är egentligen metoder avsedda för mjukvaruutveckling, och som därmed kan misstänkas missa viktiga aspekter när de tillämpas på informationssystem. I den här avhandlingen har jag studerat angreppssätt för att stödja informationssystemsutvecklingsprocessen. Dessa angreppssätt satsar alla påatt hitta aspekter av informationsystem, och att försöka mäta, simulera eller i andra former uppskatta aspekterna för att få en översikt över var mer kraft behövs i utvecklingsprocessen. Resultaten av avhandlingen inkluderar rekommendationer kring simulering av sådana aspekter, samt en model där aspekterna formulerats som kriterierför utvärdering av informationssystem. CISE-modellen (Criteria for InformationSystems Evaluation) är den främsta produkten av avhandlingen, och den gåratt använda som en checklista under informationssystemsarbete.
