The thesis aims to describe the selection of a new information system, which should lead to process streamlining and a boost in the number of customers at Rumburak s.r.o. The first chapter lays out the theoretical knowledge needed to tackle the task at hand. The following section analyzes the internal and external environment of the company and the implications thereof. The proposal portion contains a comparison of the available information systems and selects the best among them. It develops a schedule for the implementation of the new IS, along with identifying the benefits and economic evaluation of the entire proposal.

With the introduction of RIS and PACS technologies in clinical radiology, the field has become increasingly technology dependent. The quality assurance in radiology have however yet to catch on. With many quality assurance programs mainly focusing on the clinical side of radiology whilst little attention is paid to the technical aspects. This thesis serves to change that, by investigating quality assurance of radiology equipment in the workflow of hospital physicists and biomedical engineers at Södersjukhuset emergency hospital. To improve said workflows, process modelling and multi-actor system analysis was utilized in combination with the on-site inventory system Medusa. In order to model the workflows, the process modelling technique flowchart was used. To add additional information into the flowcharts, multi-actor system analysis was employed. This was done for the workflow of both scheduled and unscheduled maintenance of radiology equipment. Initially resulting in a pair of pre-study models which modelled the after the existing workflows. From said pair of pre-study models, both redundancies and main objectives for improvement were deduced. This in combination with an extensive semistructured literature review, led to a list of requirements. Two pairs of improved models were then created with the list of requirements in mind. All the models were then evaluated, including the pair of pre-study models, in workshops held with hospital physicists, biomedical engineers and respective leadership staff. These workshops contained both an open discussion and a questionnaire, asking the participants to rate the alignment of the models with the different requirements in the list. Based on the results from the workshops, one of the proposed pairs of improved models were then chosen as the final solution of an improved workflow. A workflow in which redundancies were reduced, traceability capabilities added in form of digital storage, and alignment with legislative demands from SSM assured. A step in the digitalization of Södersjukhuset. Utilizing digital technology to improve quality assurance in the workflow of radiology equipment. / I samband med introduktionen av RIS och PACS teknologi i klinisk radiologi, så har fältet blivit mer teknikdrivet. Kvalitetledning av radiologisk utrustning har däremot inte förändrats. Då de flesta kvalitetslednings program har primärt fokus på den kliniska sidan av radiologi och förbiser de tekniska aspekterna. Detta examensarbete försöker bemöta detta, genom att utreda kvalitetsledningen av radiologisk utrustning hos arbetsflödena av sjukhusfysiker och medicintekniska ingenjörer på Södersjukhuset. För att förbättra arbetsflödena, så användes processmodellering och analys av multi-aktörsystem i kombination med det lokala inventariesystemet Medusa. För att skapa en modell av arbetsflödet så användes processmodelleringstekniken flowchart. För att lägga till ytterligare information i flödena så utfördes en multi-aktörsystem analys. Detta utfördes för både förebyggande- och avhjälpande underhåll av radiologisk utrustning. Vilket resulterade i ett par av förstudiemodeller som modellerade det nuvarande arbetsflödet. Baserat på detta par av förstudiemodeller, så kunde både överflödigheter och huvudsakliga förbättringsmål härledas. Detta i kombination med en semistrukturerad litteraturundersökning, ledde till en lista med krav på modellerna. Sedan så skapades två par av modeller som förslag till förbättrat arbetsflöde, baserat på listan med krav. För att utvärdera alla modeller, inklusive förstudiemodellerna, så hölls workshops med sjukhusfysiker, medicintekniska ingenjörer och respektive chefspersonal. Dessa workshops innehöll både en öppen diskussion och ett formulär, som bad deltagarna att utvärdera de olika paren av modeller gentemot de olika kraven som hade formulerats i listan. Baserat på resultaten från dessa workshops, så valdes en av de två förslagna paren av modeller för förbättrat arbetsflöde, som en slutgiltig lösning. Ett arbetsflöde där överflödigheter har motarbetats, spårbarhet förbättrats med hjälp av digital lagring, och sammanstämning med regulatoriska krav från SSM har säkerställts. Ett steg i digitaliseringen av Södersjukhuset, genom att utnyttja digital teknik för att förbättra kvalitetledningen av radiologisk utrustning.

One of the tools used during re-engineering of an environment is the process model as modelling tool. The identification of process models within an institution is a difficult and tedious task. A problem is that often process model structures is identified for one specific project and not stored for future reuse. The ideal for institutions is to reuse process model structures within the institution. This study focused on the generic structures within the higher education application domain where the hypothesis for this study was that a generic educational process model structure for higher education institutions can be established; a process management flow procedure can be used to manage the flow within an educational process model; and that aneducational process model can be stored and reused in re-engineering efforts. The study was divided into three research questions, where the first focused on the identification of generic process model structures, the second on the usability of the process model structures within a re-engineering effort, and the last on the preservation of a process model structure. For the first research question, the identification of process model structures, three institutions were used for data collection. It was necessary to develop a requirements elicitation procedure for data collection. The structure derived was confirmed at a fourth institution. For the second research question, which focuses on the usability of process model structures, an ordinal measurement was defined to measure the usefulness of the process model structures in a reengineering effort. A re-engineering procedure was developed for re-engineering the application domain, called the process management flow procedure, and used for a re-engineering effort at one institution. Lastly, for the third research question the preservation of the process model structures, the abstraction of the process model structure was investigated as well as the feasibility of implementing the process model structures physically using existing repository software. The conclusion after the investigation of the three research questions was that the hypothesis was confirmed that there is indeed a set of process model structures within the higher education institution that are generic, preservable and reusable in a re-engineering effort. / Computing / Ph.
