    Heroku-Based Innovative Platform for Web-Based Deployment in Product Development at Axis2021Ingår i: IEEE Access, E-ISSN 2169-3536, Vol. 9, s. 10805-10819Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    The introduction of cloud technology has reduced the feedback time in software development for many companies. However, companies require significant resources to run applications in an Infrastructure as a Service. The study aims at developing an innovation platform which enables faster deployment of web-based applications. The innovation platform is an add-on for a cloud service, its purpose is to allow developers to set up and use multiple cameras in a cloud environment. Furthermore, the study investigates the drivers and value created by the platform for Axis. We developed a proof of concept built on the innovation platform, using the design science methodology and evaluated it in a focus group. The prototype was a mock version of a grocery store’s internal website, used to show the potential of the innovation platform. Moreover, we conducted semi-structured interviews to investigate the drivers for implementing the platform and the value it created. Results showed that the implementation of the prototype may make the deployment of web-based applications easier. A majority of the interviewees and the focus group participants agreed that the development of the innovation platform should continue and be tested to adopt the platform as a complement to AWS. However, the degree to which the platform should be open source needs a more clear management strategy. The prototype is seen as an innovation platform which may be used to quickly experiment with new ideas. The key drivers for implementing a prototype entails reduced cost, faster time to market and reduced complexity of web-based deployments.

    A Survey on the Perception of Innovation in a Large Product-Focused Software Organization2015Ingår i: Software Business - 6th International Conference, ICSOB 2015, Braga, Portugal, June 10-12, 2015, Proceedings, Springer, 2015, Vol. 210, s. 66-80Konferensbidrag (Refereegranskat)
    Abstract [en]

    Context. Innovation is promoted in companies to help them stay competitive. Four types of innovation are defined: product, process, business, and organizational. Objective. We want to understand the perception of the innovation concept in industry, and particularly how the innovation types relate to each other. Method. We launched a survey at a branch of a multi-national corporation. Results. From a qualitative analysis of the 229 responses, we see that the understanding of the innovation concept is somewhat narrow, and mostly related to product innovation. A majority of respondents indicate that product innovation triggers process, business, and organizational innovation, rather than vice versa. However, there is a complex interdependency between the types. We also identify challenges related to each of the types. Conclusion. Increasing awareness and knowledge of different types of innovation, may improve the innovation. Further, they cannot be handled one by one, but in their interdependent relations.

    Motivating the contributions: An Open Innovation perspective on what to share as Open Source Software2018Ingår i: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 135, s. 17-36Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Open Source Software (OSS) ecosystems have reshaped the ways how software-intensive firms develop products and deliver value to customers. However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm’s practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems.

    Reshaping Sustainable University Education in Post-Pandemic World: Lessons Learned from an Empirical Study2022Ingår i: Education Sciences, E-ISSN 2227-7102, Vol. 12, nr 8, artikel-id 524Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The outbreak of COVID-19 has affected people all around the world. Governments had no choice but to put people in self-isolation to stop the spread of the virus. As a result, all companies and educational institutions switched to working or studying from home. The purpose of the study is to investigate the impact of COVID-19 on student teaching and learning in the context of Malmo university. Furthermore, the study proposes recommendations for sustainable post-pandemic education at Malmo University. The study includes ten semi-structured interviews with students followed by a workshop with ten senior lecturers teaching bachelor's and master's courses. The study uses snowball sampling to select students for the interviews and senior lecturers for the workshop. A qualitative data analysis technique, thematic analysis, is used for data analysis on the data collected from interviews with students and the workshop with senior lecturers. The results from the study suggested that online education leads to several benefits for students, such as better time management, higher lecture attendance, flexibility, and discipline in their studies. However, the shift to online education has caused a communication deterioration between students and teachers. Less social interaction with other students leads to depression, anxiety, and stress. The recommendations for post-pandemic education include the unified selection of digital learning tools across courses, a designated budget for digital learning tools, training support, and hybrid learning methods. In conclusion, the study proposes blended and hybrid learning to improve higher education at the university, requiring digital tools to minimize students' communication barriers.

    Management tools for business model innovation: a review2022Ingår i: Innovation / [ed] Renu Agarwal; Eric Patterson; Sancheeta Pugalia; Roy Green, Routledge, 2022, s. 141-158Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    The purpose of this chapter is to identify and classify proposed business model innovation tools through a literature review of academic publications. We classified the tools into three categories: innovation process stage, strategic objective and size of firm. Our main findings are that the overall number of business model innovation (BMI) tools described in the research literature is limited mostly to facilitate design processes rather than for test or implementation purposes. Moreover, the identified tools are based on conceptual reasoning and not on empirical studies of tools used by managers. Implications for managers are that most BMI tools are intended for, and have their strength in, experimenting with the design or redesign of a business model, placing it in a value chain and value network ecosystem. As most of these BMI tools have a visual representation, such as the business model canvas, they facilitate creativity and analysis work in management groups with different functions, e.g., in workshops with visual boards. Moreover, while most BMI tools assume the profit objective it is important for managers to make the objective of the BMI process explicit as many of the tools may be used also for growth or creating new businesses. Making the objective explicit might be especially important for managers in government or non-profit organizations as these organizations often have other objectives than profit and growth. A final implication for managers is that BMI tools are mainly developed to support managers when established companies need to change their business model in three types of situations; changes due to digitalization, to develop and sharpen the company’s competitive advantages and when developing new businesses, i.e., corporate venturing.

    Open innovation using open source tools: a case study at Sony Mobile2018Ingår i: Empirical Software Engineering, ISSN 1382-3256, E-ISSN 1573-7616, Vol. 23, nr 1, s. 186-223Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Despite growing interest of Open Innovation (OI) in Software Engineering (SE), little is known about what triggers software organizations to adopt it and how this affects SE practices. OI can be realized in numerous of ways, including Open Source Software (OSS) involvement. Outcomes from OI are not restricted to product innovation but also include process innovation, e.g. improved SE practices and methods. This study explores the involvement of a software organization (Sony Mobile) in OSS communities from an OI perspective and what SE practices (requirements engineering and testing) have been adapted in relation to OI. It also highlights the innovative outcomes resulting from OI. An exploratory embedded case study investigates how Sony Mobile use and contribute to Jenkins and Gerrit; the two central OSS tools in their continuous integration tool chain. Quantitative analysis was performed on change log data from source code repositories in order to identify the top contributors and triangulated with the results from five semi-structured interviews to explore the nature of the commits. The findings of the case study include five major themes: i) The process of opening up towards the tool communities correlates in time with a general adoption of OSS in the organization. ii) Assets not seen as competitive advantage nor a source of revenue are made open to OSS communities, and gradually, the organization turns more open. iii) The requirements engineering process towards the community is informal and based on engagement. iv) The need for systematic and automated testing is still in its infancy, but the needs are identified. v) The innovation outcomes included free features and maintenance, and were believed to increase speed and quality in development. Adopting OI was a result of a paradigm shift of moving from Windows to Linux. This shift enabled Sony Mobile to utilize the Jenkins and Gerrit communities to make their internal development process better for its software developers and testers.

    Considering rigor and relevance when evaluating test driven development: A systematic review2014Ingår i: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 56, nr 4, s. 375-394Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Context

    Test driven development (TDD) has been extensively researched and compared to traditional approaches (test last development, TLD). Existing literature reviews show varying results for TDD.

    Objective

    This study investigates how the conclusions of existing literature reviews change when taking two study quality dimension into account, namely rigor and relevance.

    Method

    In this study a systematic literature review has been conducted and the results of the identified primary studies have been analyzed with respect to rigor and relevance scores using the assessment rubric proposed by Ivarsson and Gorschek 2011. Rigor and relevance are rated on a scale, which is explained in this paper. Four categories of studies were defined based on high/low rigor and relevance.

    Results

    We found that studies in the four categories come to different conclusions. In particular, studies with a high rigor and relevance scores show clear results for improvement in external quality, which seem to come with a loss of productivity. At the same time high rigor and relevance studies only investigate a small set of variables. Other categories contain many studies showing no difference, hence biasing the results negatively for the overall set of primary studies. Given the classification differences to previous literature reviews could be highlighted.

    Conclusion

    Strong indications are obtained that external quality is positively influenced, which has to be further substantiated by industry experiments and longitudinal case studies. Future studies in the high rigor and relevance category would contribute largely by focusing on a wider set of outcome variables (e.g. internal code quality). We also conclude that considering rigor and relevance in TDD evaluation is important given the differences in results between categories and in comparison to previous reviews.

    The Rise of Open Source Program Office2021Ingår i: IT Professional Magazine, ISSN 1520-9202, E-ISSN 1941-045X, Vol. 23, nr 1, s. 27-33Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The use of open-source software in business development has grown in the past five years. The rise of open source software has grabbed the attention of every industry such as e-commerce, fintech, cybersecurity, telecom, automotive, aviation, etc. This study aims to investigate how companies set up an open source program office (OSPO) to unlock the potential of OSS and to show the roadmap to set up an OSPO. We conducted two semi-structured interviews in two companies to identify the key components of open source operations. We found out that company A is more mature in open source operations compared to company B.

    Software testing in open innovation: an exploratory case study of the acceptance test harness for jenkins2015Ingår i: Proceedings of the 2015 International Conference on Software and System Process, ICSSP 2015, Tallinn, Estonia, August 24 - 26, 2015, ACM Digital Library, 2015, s. 187-191Konferensbidrag (Refereegranskat)
    Abstract [en]

    Open Innovation (OI) has gained significant attention since the term was introduced in 2003. However, little is known whether general software testing processes are well suited for OI. An exploratory case study on the Acceptance Test Harness (ATH) is conducted to investigate OI testing activities of Jenkins. As far as the research methodology is concerned, we extracted the change log data of ATH followed by five interviews with key contributors in the development of ATH. The findings of the study are threefold. First, it highlights the key stakeholders involved in the development of ATH. Second, the study compares the ATH testing activities with ISO/IEC/IEEE testing process and presents a tailored process for software testing in OI. Finally, the study underlines some key challenges that software intensive organizations face while working with the testing in OI.

    A theory of openness for software engineering tools in software organizations2018Ingår i: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 97, s. 26-45Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Context

    The increased use of Open Source Software (OSS) affects how software-intensive product development organizations (SIPDO) innovate and compete, moving them towards Open Innovation (OI). Specifically, software engineering tools have the potential for OI, but require better understanding regarding what to develop internally and what to acquire from outside the organization, and how to cooperate with potential competitors.

    Aim

    This paper aims at synthesizing a theory of openness for software engineering tools in SIPDOs, that can be utilized by managers in defining more efficient strategies towards OSS communities.

    Method

    We synthesize empirical evidence from a systematic mapping study, a case study, and a survey, using a narrative method. The synthesis method entails four steps: (1) Developing a preliminary synthesis, (2) Exploring the relationship between studies, (3) Assessing the validity of the synthesis, and (4) Theory formation.

    Result

    We present a theory of openness for OSS tools in software engineering in relation to four constructs: (1) Strategy, (2) Triggers, (3) Outcomes, and (4) Level of openness.

    Conclusion

    The theory reasons that openness provides opportunities to reduce the development cost and development time. Furthermore, OI positively impacts on the process and product innovation, but it requires investment by organizations in OSS communities. By betting on openness, organizations may be able to significantly increase their competitiveness.

    How Companies Use OSS Tools Ecosystems for Open Innovation2019Ingår i: IT Professional Magazine, ISSN 1520-9202, E-ISSN 1941-045X, Vol. 21, nr 6, s. 40-45Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Moving toward the open innovation (OI) model requires multifaceted transformations within companies. It often involves giving away the tools for product development or sharing future product directions with open tools ecosystems. Moving from the traditional closed innovation model toward an OI model for software development tools shows the potential to increase software development competence and efficiency of organizations. We report a case study in software-intensive company developing embedded devices (e.g., smartphones) followed by a survey in OSS communities such as Gerrit, Git, and Jenkins. The studied branch focuses on developing Android phones. This paper presents contribution strategies and triggers for openness. These strategies include avoid forking OSS tools, empower developers to participate in the ecosystem, steer ecosystems through contributions, create business through differentiation, and create new ecosystems. The triggers of openness are from 30 different companies with examples. Finally, openness requires a cultural change aligned with strategies and business models.

    Open Tools for Software Engineering: Validation of a Theory of Openness in the Automotive Industry2019Ingår i: Proceedings of the Evaluation and Assessment on Software Engineering, EASE 2019, Copenhagen, Denmark, April 15-17, 2019, ACM Digital Library, 2019, s. 2-11Konferensbidrag (Refereegranskat)
    Abstract [en]

    Context: Open tools (e.g., Jenkins, Gerrit and Git) offer a lucrative alternative to commercial tools. Many companies and developers from OSS communities make a collaborative effort to improve the tools. Prior to this study, we developed an empirically based theory for companies' strategic choices on the development of these tools, based on empirical observations in the telecom domain. Aim: The aim of this study is to validate the theory of openness for tools in software engineering, in another domain, automotive. Specifically, we validated the theory propositions and mapped the case companies onto the model of openness. Method: We run focus groups in two automotive companies, collecting data in a survey and follow-up discussions. We used the repertory grid technique to analyze the survey responses, in combination with qualitative data from the focus group, to validate the propositions. Results: Openness of tools has the potential to reduce development costs and time, and may lead to process and product innovation. This study confirms three out of five theory propositions, on cost and time reduction, and the complementary role of open tools. One propositions was not possible to validate due to lack of investment in OSS tools communities by both companies. However, our findings extend the fifth proposition to require management being involved for both the proactive and reactive strategy. Further, we observe that the move towards open tools happen with a paradigm shift towards openness in the automotive domain, and lead to standardization of tools. Both companies confirm that they need legal procedures for the contribution, as well as an internal champion, driving the open tools strategy. Conclusion: We validated the theory, originating from the telecom domain, partially using two automotive companies. Both case companies are classified as laggards (reactive, cost saving) in the model of openness presented in the theory. Furthermore, we would like to have more validations studies to validate the remaining quadrants (e.g., leverage, lucrativeness and leaders).

    Artificial Intelligence and Machine Learning Approaches in Digital Education: A Systematic Revision2022Ingår i: Information, E-ISSN 2078-2489, Vol. 13, nr 4, artikel-id 203Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    The use of artificial intelligence and machine learning techniques across all disciplines has exploded in the past few years, with the ever-growing size of data and the changing needs of higher education, such as digital education. Similarly, online educational information systems have a huge amount of data related to students in digital education. This educational data can be used with artificial intelligence and machine learning techniques to improve digital education. This study makes two main contributions. First, the study follows a repeatable and objective process of exploring the literature. Second, the study outlines and explains the literature's themes related to the use of AI-based algorithms in digital education. The study findings present six themes related to the use of machines in digital education. The synthesized evidence in this study suggests that machine learning and deep learning algorithms are used in several themes of digital learning. These themes include using intelligent tutors, dropout predictions, performance predictions, adaptive and predictive learning and learning styles, analytics and group-based learning, and automation. artificial neural network and support vector machine algorithms appear to be utilized among all the identified themes, followed by random forest, decision tree, naive Bayes, and logistic regression algorithms.

    An experimental evaluation of test driven development vs. test-last development with industry professionals2014Ingår i: 18th International Conference on Evaluation and Assessment in Software Engineering, EASE ’14, London, England, United Kingdom, May 13-14, 2014, ACM Digital Library, 2014, s. 50-1Konferensbidrag (Refereegranskat)
    Abstract [en]

    Test-Driven Development (TDD) is a software development approach where test cases are written before actual development of the code in iterative cycles. Context: TDD has gained attention of many software practitioners during the last decade since it has contributed several benefits to the software development process. However, empirical evidence of its dominance in terms of internal code quality, external code quality and productivity is fairly limited. Objective: The aim behind conducting this controlled experiment with professional Java developers is to see the impact of Test-Driven Development (TDD) on internal code quality, external code quality and productivity compared to Test-Last Development (TLD). Results: Experiment results indicate that values found related to number of acceptance test cases passed, McCabe's Cyclomatic complexity, branch coverage, number of lines of code per person hours, number of user stories implemented per person hours are statistically insignificant. However, static code analysis results were found statistically significant in the favor of TDD. Moreover, the results of the survey revealed that the majority of developers in the experiment prefer TLD over TDD, given the lesser required level of learning curve as well as the minimum effort needed to understand and employ TLD compared to TDD.

    Open innovation in software engineering: a systematic mapping study2016Ingår i: Empirical Software Engineering, ISSN 1382-3256, E-ISSN 1573-7616, Vol. 21, nr 2, s. 684-723Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Open innovation (OI) means that innovation is fostered by using both external and internal influences in the innovation process. In software engineering (SE), OI has existed for decades, while we currently see a faster and broader move towards OI in SE. We therefore survey research on how OI takes place and contributes to innovation in SE. This study aims to synthesize the research knowledge on OI in the SE domain. We launched a systematic mapping study and conducted a thematic analysis of the results. Moreover, we analyzed the strength of the evidence in the light of a rigor and relevance assessment of the research. We identified 33 publications, divided into 9 themes related to OI. 17/33 studies fall in the high–rigor/high–relevance category, suggesting the results are highly industry relevant. The research indicates that start-ups have higher tendency to opt for OI compared to incumbents. The evidence also suggests that firms assimilating knowledge into their internal R&D activities, have higher likelihood of gaining financial advantages. We concluded that OI should be adopted as a complementary approach to facilitate internal innovation and not to substitute it. Further research is advised on situated OI strategies and the interplay between OI and agile practices.

    Neural Network-Based Recent Research Developments in SLAM for Autonomous Ground Vehicles: A Review2023Ingår i: IEEE Sensors Journal, ISSN 1530-437X, E-ISSN 1558-1748, Vol. 23, nr 13, s. 13829-13858Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    The development of autonomous vehicles has prompted an interest in exploring various techniques in navigation. One such technique is simultaneous localization and mapping (SLAM), which enables a vehicle to comprehend its surroundings, build a map of the environment in real time, and locate itself within that map. Although traditional techniques have been used to perform SLAM for a long time, recent advancements have seen the incorporation of neural network techniques into various stages of the SLAM pipeline. This review article provides a focused analysis of the recent developments in neural network techniques for SLAM-based localization of autonomous ground vehicles. In contrast to the previous review studies that covered general navigation and SLAM techniques, this paper specifically addresses the unique challenges and opportunities presented by the integration of neural networks in this context. Existing review studies have highlighted the limitations of conventional visual SLAM, and this article aims to explore the potential of deep learning methods. This article discusses the functions required for localization, and several neural network-based techniques proposed by researchers to carry out such functions. First, it presents a general background of the issue, the relevant review studies that have already been done, and the adopted methodology in this review. Then, it provides a thorough review of the findings regarding localization and odometry. Finally, it presents our analysis of the findings, open research questions in the field, and a conclusion. A semisystematic approach is used to carry out the review.
