I denna rapport utreds en ostrukturerad och splittrad IT miljö på Electrolux. Miljön saknade flöden och processer för bland annat felhantering. Omodern hård- och mjukvara samt bristande kommunikation mellan produktorganisationen och Electrolux IT medförde förhöjd risk för nätverksattacker och virusangrepp. Situationen medförde onödiga kostnader, eftersatt säkerhet samt otillräcklig IT-stöd för slutanvändarna. Målet med detta arbete är att uppnå en enad, strukturerad och väletablerad IT-miljö med klara rutiner och flöden för felhantering av hård- och mjukvaror. Enhetliga hård- och mjukvaror samt standardiserade IT-lösningar är av stor vikt. Hinder för en migration till en väletablerad IT-miljö skulle med detta arbete också elimineras. En nulägesanalys utfördes tillsammans med en inventering av hård- och mjukvara. Detta för att få en överblick och för att förstå hur verksamheten fungerade, samt finna eventuella IT brister. Resultatet visade på behovet av en migration av en grupp datorer till en etablerad IT miljö med fungerande rutiner och processer. Implementationsplan samt manual för migration genererades i rapporten. En utvärdering av olika verktyg för begränsade administrativa rättigheter i slutanvändarnas datorer utfördes. Det bäst lämpade verktyget för Electrolux var Avecto Privilege Guard som testades och konfigurerades. Detta för att tillgodogöra produktorganisationens behov. Lösningsförslag för att möta kraven och standarden från både Electrolux-IT samt produktorganisationen framtogs och presenteras i resultatet. Resultatet av detta examensarbete påvisade ett stort behov av en IT-koordinator för en bättre kommunikation och ett bättre samarbete mellan organisationerna. En rekommendation om detta presenteras i slutsatsen tillsammans med förslag på andra förbättringar och åtgärder. / This report investigated an unstructured and fragmented IT environment at Electrolux. The environment lacked flows and processes for troubleshooting. Outdated hardware and software and a lack of communication between the product organization and the IT organization, resulted in an increased risk of network attacks and virus attacks. The situation resulted in unnecessary costs, neglected security and inadequate IT support for the end-users. The goal of this work is to achieve a unified, structured and well-established IT environment with clear procedures and flows for the troubleshooting of computer hardware and software. Uniform hardware and software as well as standardized IT solutions is of great importance. Barriers to migration to a well-established IT environment would with this work also be eliminated. A situation analysis was conducted together with an inventory of hardware and software. This was done to get an overview and to understand how the business worked, also to find possible IT failures. The results showed the need for a migration of a group of computers to an established IT environment with operational procedures and processes. An implementation plan and manual for the migration was generated in the report. An evaluation of the different tools for limited administrative rights on end-user computers was also performed. The most suitable tool for Electrolux was Avecto Privilege Guard which was tested and configured. This was done to assimilate the product organization’s needs. Solution´s to meet the requirements from both Electrolux IT and product organization was developed and is presented in the results. The results of this thesis showed a great need of an IT coordinator for a better communication and better cooperation between the organizations. A recommendation regarding this was presented to Electrolux together with suggestions for improvements and measures.

Today’s world is a network of interconnected systems that are always running to facilitate information exchange so people can carry out their daily activities. Software applications are constantly evolving to meet the increasing expectations of the growing market, thereby giving rise to the development of large complex systems. It is very likely for these complex systems to encounter bugs which is a situation that can cause errors in software. These bugs can prevent the systems from operating as intended, slowing down software development and deployment, and causing delays in deadlines. This study undertook a systematic literature review to find trends in the field of bug prioritization. Software bug prioritization can help developers determine the order of fixing bugs by assigning priority levels based on the severity analysis. This study aims to identify the most promising techniques that can change the bug prediction and resolution process. It is observed that machine learning techniques (ML) have been gaining popularity in addressing the bug prioritization issue since they can automatically assign priority levels. However, these ML techniques also have limitations addressed in this study along with a taxonomic classification of identified techniques. The review obtained 34 manuscripts based on study selection criteria. These manuscripts discovered 63 unique bug prioritization techniques, including a mix of ML, data reduction and hybrid techniques. It is evident that though these techniques perform automatic prioritization, they can sometimes be slow and lack consistency in the accuracy of results.

The title of graduation work is development of techniques of software testing. The objective of research is studying of the testing process, defect types in the software and their tracking, methods of creating and applying test cases, and development of auto-test project for the web service “Expert”. An additional objective is to conduct stress testing for the web service "Expert". The first part is devoted to the theoretical foundations of testing: a place of testing in software development, testing process in it-companies, review of defects and their tracking, and techniques of creating tests and their applying. The second part is devoted to the review of software for load testing and it’s practical usage for testing the web service “Expert”. The last part is devoted to the study of automation functional testing and development of the auto test project for the web service “Expert”. The graduation work consists of an introduction, 12 chapters and conclusion on 106 pages, including 55 figures and the list of 15 references. / Тема выпускной квалификационное работы: разработка методики тестирования программного обеспечения.
