  • Using Exploration Focused Techniques to Augment Search-Based Software Testing: An Experimental Evaluation
  • 2016
  • Ingår i: 2016 9th Ieee International Conference on Software Testing, Verification and Validation. - 2381-2834. - 978-1-5090-1827-7 ; s. 69-79

    • Search-based software testing (SBST) often uses objective-based approaches to solve testing problems. There are, however, situations where the validity and completeness of objectives cannot be ascertained, or where there is insufficient information to define objectives at all. Incomplete or incorrect objectives may steer the search away from interesting behavior of the software under test (SUT) and from potentially useful test cases. This papers investigates the degree to which exploration-based algorithms can be used to complement an objective-based tool we have previously developed and evaluated in industry. In particular, we would like to assess how exploration-based algorithms perform in situations where little information on the behavior space is available a priori. We have conducted an experiment comparing the performance of an exploration-based algorithm with an objective-based one on a problem with a high-dimensional behavior space. In addition, we evaluate to what extent that performance degrades in situations where computational resources are limited. Our experiment shows that exploration-based algorithms are useful in covering a larger area of the behavior space and result in a more diverse solution population. Typically, of the candidate solutions that exploration-based algorithms propose, more than 80% were not covered by their objective-based counterpart. This increased diversity is present in the resulting population even when computational resources are limited. We conclude that exploration-focused algorithms are a useful means of investigating high-dimensional spaces, even in situations where limited information and limited resources are available.

  • Prioritization of quality requirements: State of practice in eleven companies
  • 2011
  • Ingår i: 2011 IEEE 19th International Requirements Engineering Conference, RE 2011; Trento; 29 August 2011 through 2 September 2011. - 978-145770923-4 ; s. 69-78

    • 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.

  • Selecting creativity techniques for creative requirements: An evaluation of four techniques using creativity workshops
  • 2015
  • Ingår i: 23rd IEEE International Requirements Engineering Conference, RE 2015, Ottawa, Canada, 24-28 August. - 978-146736905-3 ; s. 66-75
  • Konferensbidrag (refereegranskat)abstract
    • Requirements engineering is recognized as a creative process where stakeholders jointly discover new creative ideas for innovative and novel products that eventually are expressed as requirements. This paper evaluates four different creativity techniques, namely Hall of Fame, Constraint Removal, Brainstorming, and Idea Box, using creativity workshops with students and industry practitioners. In total, 34 creativity workshops were conducted with 90 students from two universities, and 86 industrial practitioners from six companies. The results from this study indicate that Brainstorming can generate by far the most ideas, while Hall of Fame generates most creative ideas. Idea Box generates the least number of ideas, and the least number of creative ideas. Finally, Hall of Fame was the technique that led to the most number of requirements that was included in future releases of the products.

  • Group Maturity and Agility, Are They Connected? - A Survey Study
  • 2015
  • Ingår i: EUROMICRO Conference on Software Engineering and Advanced Applications (SEAA 2015), August 26-28. - 978-1-4673-7585-6 ; 41, s. 1-8
  • Konferensbidrag (refereegranskat)abstract
    • The focus on psychology has increased within software engineering due to the project management innovation "agile development processes". The agile methods do not explicitly consider group development aspects; they simply assume what is described in group psychology as mature groups. This study was conducted with 45 employees and their twelve managers (N=57) from two SAP customers in the US that were working with agile methods, and the data were collected via an online survey. The selected Agility measurement was correlated to a Group Development measurement and showed significant convergent validity, i.e., a more mature team is also a more agile team. This means that the agile methods probably would benefit from taking group development into account when its practices are being introduced.

  • Evidence-based Timelines for User eXperience Software Process Improvement Retrospectives
  • 2016
  • Ingår i: 2016 42nd Euromicro Conference on Software Engineering and Advanced Applications (Seaa). - 978-1-5090-2819-1 ; s. 59-62
  • Konferensbidrag (refereegranskat)abstract
    • We performed a retrospective meeting at a case company to reflect on its decade of Software Process Improvement (SPI) activities for enhancing UX integration. We supported the meeting by a pre-generated timeline of the main activities. This approach is a refinement of a similar approach that is used in Agile projects to improve effectiveness and decrease memory bias of retrospective meetings. The method is evaluated through gathering practitioners' view using a questionnaire. We conclude that UX research and practice can benefit from the SPI body of knowledge. We also argue that a cross-section evidence-based timeline retrospective meeting is useful for enhancing UX work in companies, especially for identifying and reflecting on `organizational issues'. This approach also provides a cross-section longitudinal overview of the SPI activities that cannot easily be gained in other common SPI learning approaches.

  • An initial analysis of differences in software engineers' attitudes towards organizational change
  • 2016
  • Ingår i: 9th International Workshop on Cooperative and Human Aspects of Software Engineering, CHASE 2016; Austin; United States; 16 May 2016. - 978-145034155-4 ; s. 1-7
  • Konferensbidrag (refereegranskat)abstract
    • The ability to manage change is important in software engineering organizations, where rapid progress in technologies and constantly evolving methodologies create a turbulent environment. Research has identified employees’ attitudes towards organizational change as a key factor in the change process. Nonetheless, few studies exist that explore such attitudes in a software engineering context. The nature of change efforts is such that they often do not equally affect the various roles in the organization, which indicates that the roles may hold different attitudes. This study aimed to verify the existence of these presumed differences in attitudes towards organizational change between roles in a software engineering organization and to identify factors that contribute to these differences. The result of a survey (N=51) confirmed that there were significant differences, and that the software developers had a more positive attitude towards change and had deeper knowledge about the intended outcome compared to the line managers. The result of in-depth interviews (N=11) revealed that the software engineers evaluate the planned change in relation to the norms, values and standards of their peer group, meaning that an employee will have a positive attitude towards a change if its result is likely to make, or has made, it easier for him/her to uphold the peer group’s norms and values.

  • Towards a Behavioral Software Engineering
  • 2014
  • Ingår i: CHASE 2014 Proceedings of the 7th International Workshop on Cooperative and Human Aspects of Software Engineering. - 978-1-4503-2860-9 ; s. 48-55

    • Throughout the history of Software Engineering (SE) it has been repeatedly found that the humans involved, i.e. the engineers and developers in addition to other stakeholders, are a key factor in determining project outcomes and success. However, the amount of research that focuses on human aspects has been limited compared to research with technology or process focus. With increasing maturity of the field, interest in agile methods and a growing dissatisfaction with the continued challenges of developing high-quality software on time, the amount of SE research putting human aspect in primary focus has increased. In this paper we argue that a synthesized view of the emerging human-focused SE research is needed and can add value through giving focus, direction and help identify gaps. Taking cues from the addition of Behavioral Economics as an important part of the area of Economics we propose the term Behavioral Software Engineering (BSE) as an umbrella concept for research that focus on behavioral and social aspects in the work activities of software engineers. We propose that a model based on three units of analysis can give structure and point to concepts that are important for BSE. To add detail to this model we are conducting a systematic review to map out what is currently known. To exemplify the model and the area we here present the results from a subset of the identified concepts.
