Problem vid kravhantering : kravhantering i IT-projekt hos systemleverantörer

Requirements engineering is essential to succeed in developing IT systems that meet the client's expectations and maintaining the budget, which should be considered the goal for an IT-project. Poor requirements engineering is one of the main reasons why IT projects fail. A poorly conducted requirements engineering process can result in several negative consequences, which is common. A well-functioning requirements engineering process can save a lot of money and facilitate achieving good results.In this qualitative case study, we examine how the system providers are using requirements engineering and the problems they experience with this. The aim is to contribute with knowledge about the problems in requirements engineering, what the consequences are and how these can be countered.This qualitative case study was conducted abductivly where empirical data were collected through interviews in two different organizations. The studied organizations are system suppliers within different areas and are in this study anonymous. The empirical data was analyzed and discussed based on relevant theories of requirements engineering and the problems that previous research surveyed. We have found problems and decided to categorize them under the headings; quality of requirements, change, traceability, communication, knowledge, methodology and resources. The results indicate that requirements engineering is a complex subject due to its inconsistent iterative nature and because it involves many different processes and actors. This makes it difficult, but not impossible to succeed in.When problem occurs, they lead to additional costs and delays. To avoid the pitfalls the study has identified, the key is awareness, experience and to follow the ways of work, adapting to situations and constantly try to improve the ways of working.The study's findings does confirm in many cases the difficulties mentioned in previous research, but also points to that there are ways to prevent, deter and prevent these. The importance of following work methods, processes and use appropriate tools becomes clear when the studied organizations emphasize that it is when they depart from these that the problems arise. The study shows that it is possible to achieve a good result with requirements engineering which both previous research and the studied organizations proves
