Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University. All nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM’s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting. In the Swedish system, SSM’s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility. Accordingly, the reporting differs somewhat between facilities. The number of reports in the Swedish system is relatively large, with a frequency of about 400 per year. Internationally, a system called the International Reporting System for Operating Experience (IRS) has been developed, through which the participating countries exchange experience to improve the safety of nuclear power plants. The IRS reporting frequency is about 100 per year in total, and Sweden contributes to IRS with 1-2 reports per year. This report accounts for a comparison of the two report systems, including some differences and similarities that have been identified. The result shows that the Swedish system covers IRS well but does not have the same comprehensive classification of events and the same standardized format of reporting as the IRS system. The conclusion is that some improvements may be made to the Swedish system, which would facilitate the international exchange of experience at the Swedish nuclear power plants.

Football is the world’s biggest sport, and every match requires a referee who is responsible for interpreting and enforcing the Laws of the Game. In Sweden, an area for improvement for referees is the user experience of the administration tool used to collect data about matches. By enhancing existing tools and systems, there is potential for greater efficiency and ease of use in administrative tasks performed by the referee. By following the Double Diamond Model of Design, this study investigated a suitable way to design an interface for referees covering the activities they perform in conjunction with a match, including the administrative part of match reporting. In the first phase, Discover, information about the referee’s activities, pain points, and wants was collected through interviews and an observation. The data was then organised and analysed in the Define phase, through affinity diagramming and by creating a current state map. In the Develop phase, different interface solutions to the identified activities and issues were explored through a Crazy 8 session. Lastly, the final Deliver phase consisted of three iterations of creating prototypes, which were evaluated through usability testing, a design critique, and a final user test.  The major pain point that was identified during the study’s first two phases was filling out the referee match report in the administrative system after each match based on the notes taken during it. Additional activities and aspects were also discovered that had an impact on the design concept for a smartphone. The design proposal consisted of three parts: (1) a referee feed, including information that might be relevant to the referee when preparing for a match; (2) a reporting tool for reporting events, in which it would be possible to report them live during the match instead of after it; and (3) the option to give feedback on the players, coaches, and supporters. While the reporting of penalty misses was discovered to need further consideration, testing mainly resulted in positive feedback about the concept and design, specifically because it removed a major pain point in their work after the match, thus indicating that it serves its purpose and could be used in a first launch of the product. One interesting finding was the perception of the mobile device and how it affects the overall solution. Although the screen size of a smartphone offers more potential design solutions and functionalities, referees feel it might be unprofessional to carry a phone onto the pitch. / Fotboll är världens största sport, och varje match kräver en domare som ansvarar för att tolka och upprätthålla spelreglerna. Ett förbättringsområde för domare i Sverige är användarupplevelsen i det administreringsverktyg som används för att samla in data om matcher. Genom att förbättra befintliga verktyg och system finns det potential för större effektivitet och användarvänlighet i de administrativa uppgifter som domaren utför. Genom att följa metoden Double Diamond undersöktes i denna studie ett lämpligt sätt att designa ett gränssnitt för domare, som täcker de aktiviteter de behöver utföra i samband med match, inklusive den administrativa delen av matchrapporteringen. I den första fasen, Discover, samlades data in om domarens aktiviteter, behov och önskemål, genom intervjuer och en observation. Informationen organiserades och analyserades sedan i Define-fasen, genom affinity diagramming och skapandet av en current state map. I Develop-fasen utforskades olika gränssnittslösningar för de identifierade aktiviteterna och problemen genom en Crazy 8-session. Slutligen bestod den sista Deliver-fasen av tre iterationer med skapande av prototyper, som utvärderades genom användbarhetstester, en design critique och ett slutligt användartest. Det största problemet som identifierades under studiens två första faser var att fylla i matchrapporten i administreringsverktyget efter varje match, baserat på anteckningarna som skrivits under den. Fler aktiviteter och aspekter identifierades också som hade en inverkan på designförslaget för smartphone. Det framtagna designförslaget bestod av tre delar: (1) ett domarflöde innehållande information som kan vara relevant för domaren när hen förbereder sig för en match, (2) ett domarverktyg för att rapportera händelser, i vilket det är möjligt att rapportera dessa live under matchen i stället för efter den, och (3) möjligheten att ge feedback om spelarna, tränarna och supportrarna. Medan hanteringen för att rapportera in straffmissar behöver utredas mer, resulterade testerna främst i positiv feedback gällande konceptet och designen, framför allt då det underlättade arbetet med matchrapporten efter matchen, vilket tyder på att den tjänar sitt syfte och kan användas vid en första lansering av produkten. En intressant iakttagelse var uppfattningen och synen av mobilenheten och hur den påverkar den övergripande lösningen. Även om skärmstorleken på en smartphone erbjuder fler potentiella designlösningar och funktioner, kan domare tycka att det känns oprofessionellt att bära med sig en telefon på planen.
