- In this study, we respond to calls for further investigation on why and how scientists choose to commercialize their research. Mowery (University entrepreneurship and technology transfer: process design, and intellectual property, Elsevier, Oxford 2005), in his criticism of the US-system, emphasizes the need for multiple channels between university and industry. His argument makes the case of Sweden interesting, where the researchers own the intellectual property of their research. Sweden thus constitutes a unique case where data can be found on which choices researchers make in a setting where a variety of channels for transfer are available. Our empirical data, collected through case studies, allowed for the expansion of the typology for mechanisms for transfer of academic research as well as the development of a typology for determinants for researchers' choice to engage in transfer of research. Apart from those contributions to the theoretic discussion, the data also provided policy implications.

- In Swedish municipalities, householders are addressed as important actors in the efforts to improve the quality of sewage sludge. Householders and sanitation professionals are regarded as integrated and active co-producers of the sanitation system, while limited by the functions offered by the technical and organizational structure. Through interviews with both householders and sanitation professionals, recognition of interdependence was identified in both groups although more communication with counterpart was asked for. If the aim is to increase sustainability in the sanitation system, regardless of technical changes, we argue that two-way communication between householders and sanitation professionals needs to increase and embrace not only advice about choice of products and ways to carry out water related activities, but also planning of activities, feedback on results and other aspects of interest.

The impact of a proposal for innovation measurement in the software industry
- 2020
-
Ingår i: International Symposium on Empirical Software Engineering and Measurement. - New York, NY, USA : IEEE Computer Society. - 1949-3789 .- 1949-3770. - 9781450375801

Konferensbidrag (refereegranskat)abstract
- Background: Measuring an organization's capability to innovate and assessing its innovation output and performance is a challenging task. Previously, a comprehensive model and a suite of measurements to support this task were proposed. Aims: In the current paper, seven years since the publication of the paper titled Towards innovation measurement in the software industry, we have reflected on the impact of thework. Method:We have mainly relied on quantitative and qualitative analysis of the citations of the paper using an established classification schema. Results: We found that the article has had a significant scientific impact (indicated by the number of citations), i.e., (1) cited in literature from both software engineering and other fields, (2) cited in grey literature and peerreviewed literature, and (3) substantial citations in literature not published in the English language. However, we consider a majority of the citations in the peer-reviewed literature (75 out of 116) as neutral, i.e., they have not used the innovation measurement paper in any substantial way. All in all, 38 out of 116 have used, modified or based their work on the definitions, measurements or the model proposed in the article. This analysis revealed a significant weakness of the citing work, i.e., among the citing papers, we found only two explicit comparisons to the innovation measurement proposal, and we found no papers that identify weaknesses of said proposal. Conclusions: This work highlights the need for being cautious of relying solely on the number of citations for understanding impact, and the need for further improving and supporting the peer-review process to identify unwarranted citations in papers. © 2020 IEEE Computer Society.

- Requirements Engineering has attracted a great deal of attention from researchers and practitioners in recent years. This increasing interest requires academia to provide students with a solid foundation in the subject matter. In Requirements Engineering Education (REE), it is important to cover three fundamental topics: traditional analysis and modeling skills, interviewing skills for requirements elicitation, and writing skills for specifying requirements. REE papers report about using role playing as a pedagogical tool; however, there is a surprising lack of empirical evidence on its utility. In this paper we investigate whether a higher grade in a role playing project have an effect on students' score in an individual written exam in a Requirements Engineering course. Data are collected from 412 students between the years of 2007 and 2014 at Lund University and Chalmers | University of Gothenburg. The results show that students who received a higher grade in the role playing project scored statistically significant higher in the written exam compared to the students with a lower role playing project grade.

Tidskriftsartikel (refereegranskat)abstract
- Cognition plays a fundamental role in most software engineering activities. This article provides a taxonomy of cognitive concepts and a survey of the literature since the beginning of the Software Engineering discipline. The taxonomy comprises the top-level concepts of perception, attention, memory, cognitive load, reasoning, cognitive biases, knowledge, social cognition, cognitive control, and errors, and procedures to assess them both qualitatively and quantitatively. The taxonomy provides a useful tool to filter existing studies, classify new studies, and support researchers in getting familiar with a (sub) area. In the literature survey, we systematically collected and analysed 311 scientific papers spanning five decades and classified them using the cognitive concepts from the taxonomy. Our analysis shows that the most developed areas of research correspond to the four life-cycle stages, software requirements, design, construction, and maintenance. Most research is quantitative and focuses on knowledge, cognitive load, memory, and reasoning. Overall, the state of the art appears fragmented when viewed from the perspective of cognition. There is a lack of use of cognitive concepts that would represent a coherent picture of the cognitive processes active in specific tasks. Accordingly, we discuss the research gap in each cognitive concept and provide recommendations for future research.

Factorial validity and invariance of the Life Satisfaction Index in older people across groups and time: Addressing the heterogeneity of age, functional ability, and depression.
- 2012
-

Tidskriftsartikel (refereegranskat)abstract
- In the last decades, extensive research efforts have been directed at exploring life satisfaction in old age, and the Life Satisfaction Index A scale (LSIA), developed by Neugarten et al. in the 1960s, is one of the most commonly used instruments. However, studies have focused on predicting and comparing changes in people’s life satisfaction without testing if the LSIA instrument is equally valid for different subgroups of people. The present study investigated the underlying dimensions of the LSIA in a Swedish population (n=1402) of people 60−96 years of age. The study also examined factorial invariance across age, gender, functional ability and depression during a six-year period. The results showed that while a five-factor solution of the LSIA did not exhibit an acceptable fit to the data, a three-factor solution did show a close fit. The two three-factor models that demonstrated the best fit showed invariance across gender and across time, but noninvariance across groups with different levels of reduced functional ability, depressive symptoms and age. These findings suggest that the psychometric properties of life satisfaction instruments like the LSIA need to be taken into consideration before drawing conclusions about life satisfaction when comparing older people of different ages and with different depression and function levels.

Tidskriftsartikel (refereegranskat)abstract
- Software engineering research is evolving and papers are increasingly based on empirical data from a multitude of sources, using statistical tests to determine if and to what degree empirical evidence supports their hypotheses. To investigate the practices and trends of statistical analysis in empirical software engineering (ESE), this paper presents a review of a large pool of papers from top-ranked software engineering journals. First, we manually reviewed 161 papers and in the second phase of our method, we conducted a more extensive semi-automatic classification of papers spanning the years 2001–2015 and 5196 papers. Results from both review steps was used to: i) identify and analyse the predominant practices in ESE (e.g., using t-test or ANOVA), as well as relevant trends in usage of specific statistical methods (e.g., nonparametric tests and effect size measures) and, ii) develop a conceptual model for a statistical analysis workflow with suggestions on how to apply different statistical methods as well as guidelines to avoid pitfalls. Lastly, we confirm existing claims that current ESE practices lack a standard to report practical significance of results. We illustrate how practical significance can be discussed in terms of both the statistical analysis and in the practitioner's context. © 2019 Elsevier Inc.

Group development and group maturity when building agile teams: A qualitative and quantitative investigation at eight large companies
- 2017

Tidskriftsartikel (refereegranskat)abstract
- The agile approach to projects focuses more on close-knit teams than traditional waterfall projects, which means that aspects of group maturity become even more important. This psychological aspect is not much researched in connection to the building of an "agile team." The purpose of this study is to investigate how building agile teams is connected to a group development model taken from social psychology. We conducted ten semi-structured interviews with coaches, Scrum Masters, and managers responsible for the agile process from seven different companies, and collected survey data from 66 group-members from four companies (a total of eight different companies). The survey included an agile measurement tool and the one part of the Group Development Questionnaire. The results show that the practitioners define group developmental aspects as key factors to a successful agile transition. Also, the quantitative measurement of agility was significantly correlated to the group maturity measurement. We conclude that adding these psychological aspects to the description of the "agile team" could increase the understanding of agility and partly help define an "agile team." We propose that future work should develop specific guidelines for how software development teams at different maturity levels might adopt agile principles and practices differently.

Group Maturity and Agility, Are They Connected? - A Survey Study
- 2015

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.

What Makes Effective Leadership in Agile Software Development Teams?
- 2022
-
Ingår i: International Conference on Software Engineering. - New York, NY, USA : IEEE Computer Society. - 9781450392211 ; , s. 2402-2414

Konferensbidrag (refereegranskat)abstract
- Effective leadership is one of the key drivers of business and project success, and one of the most active areas of management research. But how does leadership work in agile software development, which emphasizes self-management and self-organization and marginalizes traditional leadership roles? To find out, this study examines agile leadership from the perspective of thirteen professionals who identify as agile leaders, in different roles, at ten different software development companies of varying sizes. Data from semi-structured interviews reveals that leadership: (1) is dynamically shared among team members; (2) engenders a sense of belonging to the team; and (3) involves balancing competing organizational cultures (e.g. balancing the new agile culture with the old milestone-driven culture). In other words, agile leadership is a property of a team, not a role, and effectiveness depends on agile team members' identifying with the team, accepting responsibility, and being sensitive to cultural conflict.
