- Requirements prioritization is recognized as an important but challenging activity in software product development. For a product to be successful, it is crucial to find the right balance among competing quality requirements. Although literature offers many methods for requirements prioritization, the research on prioritization of quality requirements is limited. This study identifies how quality requirements are prioritized in practice at 11 successful companies developing software intensive systems. We found that ad-hoc prioritization and priority grouping of requirements are the dominant methods for prioritizing quality requirements. The results also show that it is common to use customer input as criteria for prioritization but absence of any criteria was also common. The results suggests that quality requirements by default have a lower priority than functional requirements, and that they only get attention in the prioritizing process if decision-makers are dedicated to invest specific time and resources on QR prioritization. The results of this study may help future research on quality requirements to focus investigations on industry-relevant issues.

- Background: There is a need for effcient regression testing in most software development organizations. Often the proposed solutions involve automation. However, despite this being a well researched area, research results are rarely applied in industrial practice. Aim: In this paper we aim to bridge the gap between research and practice by providing examples of how evidence-based regression testing approaches can be adopted in industry. We also discuss challenges for the research community. Method: An industrial case study was carried out to evaluate the possibility to improve regression testing at Sony Ericsson Mobile Communications. We analyse the procedure undertaken based on frameworks from the evidence based software engineering, EBSE, paradigm (with a focus on the evidence) and automation literature (with a focus on the practical effects). Results: Our results pinpoint the need for systematic approaches when introducing a new tool. Practitioners and researchers need congruent guidelines supporting the appraisal of both the evidence base and the pragmatic effects, both direct but also indirect, of the changes. This is illustrated by the introduction of the automation perspective.
