- Complex decision-making is a prominent aspect of requirements engineering (RE) and the need for improved decision support for RE decision-makers has been identified by a number of authors in the research literature. A first step toward better decision support in requirements engineering is to understand multifaceted decision situations of decision-makers. In this paper, the focus is on RE decision-making in large scale bespoke development. The decision situation of RE decision-makers on a subsystem level has been studied at a systems engineering company and is depicted in this paper. These situations are described in terms of, e.g., RE decision matters, RE decision-making activities, and RE decision processes. Factors that affect RE decision-makers are also identified.

- Software requirements are often formulated on different levels and hence they are difficult to compare to each other. To address this issue, a model that allows for placing requirements on different levels has been developed. The model supports both abstraction and refinement of requirements, and hence requirements can both be compared with each other and to product strategies. Comparison between requirements will allow for prioritization of requirements, which in many cases is impossible if the requirements are described on different abstraction levels. Comparison to product strategies will enable early and systematic acceptance or dismissal of requirements, minimizing the risk for overloading. This paper presents an industrial evaluation of the model. It has been evaluated in two different companies, and the experiences and findings are presented. It is concluded that the requirements abstraction model provides helpful improvements to the industrial requirements engineering process.

Requirements Abstraction Model

Tidskriftsartikel (refereegranskat)abstract
- Software requirements arrive in different shapes and forms to development organizations. This is particularly the case in market-driven requirements engineering, where the requirements are on products rather than directed towards projects. This results in challenges related to making different requirements comparable. In particular, this situation was identified in a collaborative effort between academia and industry. A model, with four abstraction levels, was developed as a response to the industrial need. The model allows for placement of requirements on different levels and supports abstraction or break down of requirements to make them comparable to each other. The model was successfully validated in several steps at a company. The results from the industrial validation point to the usefulness of the model. The model will allow companies to ensure comparability between requirements, and hence it generates important input to activities such as prioritization and packaging of requirements before launching a development project.

Forskningsöversikt (refereegranskat)abstract
- One of the main goals of an applied research field such as requirements engineering is the transfer of research results to industrial use. To promote industrial adoption of technologies developed in academia, researchers need to provide tangible evidence of the advantages of using them. This can be done through industry validation, enabling researchers to test and validate technologies in a real setting with real users and applications. The evidence obtained, together with detailed information on how the validation was conducted, offers rich decision support material for industrial practitioners seeking to adopt new technologies. This paper presents a comprehensive systematic literature review of all papers published in the Requirements Engineering journal containing any type of technology evaluation. The aim is to gauge the support for technology transfer, i.e., to what degree industrial practitioners can use the reporting of technology evaluations in the journal as decision support for adopting the technologies in industrial practice. Findings show that very few evaluations offer full technology transfer support, i.e., have a realistic scale, application or subjects. The major improvement potential concerning support for technology transfer is found to be the subjects used in the evaluations. Attaining company support, including support for using practitioners as subjects, is vital for technology transfer and for researchers seeking to validate technologies.
