Abstract [sv]

Kravhantering är en viktig del av systemutvecklingsprocessen. Genom att samla in, analysera och prioritera krav skapas en tydlig bild av hur ett framtida system ska fungera. De krav som fastställs kan användas för utvärdering av förslag från leverantörer och senare i systemutvecklingsprocessen för utvärdering av prototyper. Kraven kan även användas när ett system ska testas, för att se om de krav som ställts på funktionalitet uppfylls. Syftet med denna uppsats är att undersöka om kravhantering i praktiken skiljer sig från vad den teori som används i uppsatsen förespråkar. För att undersöka detta har en fallstudie genomförts för att se hur krav samlats in, analyserats och prioriterats. Fallstudien undersöker även hur dessa krav använts i senare delar av systemutvecklingsprocessen. Studien visar att de tekniker som teorin tar upp delvis används i fallet. Dock är inte uppdelningen mellan olika tekniker lika tydlig i praktiken som i teorin. I det fall vi studerat används kraven för att utvärdera förslag från potentiella leverantörer, utvärdera prototyper och testa systemet inför leverans. 

Abstract [en]

Requirement management is an important part in the system development process. Gathering, analyzing and prioritizing system requirements clarifies how a future system should work. Requirements may be used in different parts of the system development process. For example it may be used when a system offer or prototype is to be evaluated. It may also be used when a system is tested to make sure it manages to fulfill functional requirements. The purpose of this paper is to investigate what requirement management looks like in reality compared to a choice of theoretical methods. This is made through a case study where the focus has been on gathering, analyzing and prioritizing requirements. The case study also investigates how these requirements are used later in the system development process. The result of our case study shows that techniques from our chosen theory are partly used in reality. It was clear that the techniques were mixed rather than used separately and that they are not used exactly as the theory suggests. In our case study the requirements were used to evaluate system offers, prototypes and to test the system before it was delivered.
