Tidskriftsartikel (refereegranskat)abstract
- Software engineering is decision intensive. Evidence-based software engineering is suggested for decision-making concerning the use of methods and technologies when developing software. Software development often includes the reuse of software assets, for example, open-source components. Which components to use have implications on the quality of the software (e.g., maintainability). Thus, research is needed to support decision-making for composite software. This paper presents a roadmap for research required to support evidence-based decision-making for choosing and integrating assets in composite software systems. The roadmap is developed as an output from a 5-year project in the area, including researchers from three different organizations. The roadmap is developed in an iterative process and is based on (1) systematic literature reviews of the area; (2) investigations of the state of practice, including a case survey and a survey; and (3) development and evaluation of solutions for asset identification and selection. The research activities resulted in identifying 11 areas in need of research. The areas are grouped into two categories: areas enabling evidence-based decision-making and those related to supporting the decision-making. The roadmap outlines research needs in these 11 areas. The research challenges and research directions presented in this roadmap are key areas for further research to support evidence-based decision-making for composite software. © 2021 The Authors.

- Selecting sourcing options for software assets and components is an important process that helps companies to gain and keep their competitive advantage. The sourcing options include: in-house, COTS, open source and outsourcing. The objective of this paper is to further refine, extend and validate a solution presented in our previous work. The refinement includes a set of decision-making activities, which are described in the form of a process-line that can be used by decision-makers to build their specific decision-making process. We conducted five case studies in three companies to validate the coverage of the set of decision-making activities. The solution in our previous work was validated in two cases in the first two companies. In the validation, it was observed that no activity in the proposed set was perceived to be missing, although not all activities were conducted and the activities that were conducted were not executed in a specific order. Therefore, the refinement of the solution into a process-line approach increases the flexibility and hence it is better in capturing the differences in the decision-making processes observed in the case studies. The applicability of the process-line was then validated in three case studies in a third company. © 2017 Elsevier Inc.

- Knowledge translation is defined, in health sciences, as 'the exchange, synthesis and ethically sound application of research results in practice'. The objective of this paper is to implement and conduct a feasibility evaluation of a knowledge translation framework in software engineering. We evaluated the outcome of the knowledge translation framework in an industrial setting, along with the effectiveness of the interventions undertaken as part of knowledge translation in a multi-case study. The results of the evaluation suggest that the practitioners perceive the knowledge translation framework to be valuable and useful. In conclusion, this paper contributes towards the reporting of a systematic implementation of knowledge translation and evaluating its use in software engineering. © 2019 IEEE.

Konferensbidrag (refereegranskat)abstract
- Usage of software engineering research in industrial practice is a well-known challenge. Synthesis of knowledge from multiple research studies is needed to provide evidence-based decision-support for industry. The objective of this paper is to present a vision of how a knowledge translation framework may look like in software engineering research, in particular how to translate research evidence into practice by combining contextualized expert opinions with research evidence. We adopted the framework of knowledge translation from health care research, adapted and combined it with a Bayesian synthesis method. The framework provided in this paper includes a description of each step of knowledge translation in software engineering. Knowledge translation using Bayesian synthesis intends to provide a systematic approach towards contextualized, collaborative and consensus-driven application of research results. In conclusion, this paper contributes towards the application of knowledge translation in software engineering through the presented framework. © 2019 Association for Computing Machinery.

Large scale reuse of microservices using DevOps andInnerSource practices - A longitudinal case study
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Contemporary practices such as InnerSource and DevOps promote software reuse. This study investigates the implications of using contemporary practices on software reuse. In particular, we investigate the costs, benefits, challenges, and potential improvements in contemporary reuse at Ericsson. We performed the study in two phases: a) the initial data collection based on a combination of data collection methods (e.g., interviews, discussions, company portals), and b) a follow-up group discussion after a year to understand the status of the challenges and improvements identified in the first phase. Our results indicate that developing reusable assets resulted in upfront costs, such as additional effort in ensuring compliance. Furthermore, development with reuse also resulted in additional effort, for example, in integrating and understanding reusable assets. Ericsson perceived the additional effort as an investment resulting in long-term benefits such as improved quality, productivity, customer experience, and way of working. Ericsson's main challenge was increased pressure on the producers of reusable assets, which was mitigated by scaling the InnerSource adoption. InnerSource success is evident from the increase in the contributions to reusable assets. In addition, Ericsson implemented measures such as automating the compliance check, which enhanced the maturity of reusable assets and resulted in increased reuse.

Forskningsöversikt (refereegranskat)abstract
- Background: Modern Code Review (MCR) is a lightweight alternative to traditional code inspections. While secondary studies on MCR exist, it is uanknown whether the research community has targeted themes that practitioners consider important.Objectives: The objectives are to provide an overview of MCR research, analyze the practitioners' opinions on the importance of MCR research, investigate the alignment between research and practice, and propose future MCR research avenues.Method: We conducted a systematic mapping study to survey state of the art until and including 2021, employed the Q-Methodology to analyze the practitioners' perception of the relevance of MCR research, and analyzed the primary studies' research impact.Results: We analyzed 244 primary studies, resulting in five themes. As a result of the 1,300 survey data points, we found that the respondents are positive about research investigating the impact of MCR on product quality and MCR process properties. In contrast, they are negative about human factor- and support systems-related research.Conclusion: These results indicate a misalignment between the state of the art and the themes deemed important by most survey respondents. Researchers should focus on solutions that can improve the state of MCR practice. We provide an MCR research agenda that can potentially increase the impact of MCR research. © 2023 Copyright held by the owner/author(s).

- Background: Empirical studies involving human participants need to follow procedures to avoid causing harm to the subjects. However, it is not always clear how researchers should report these procedures. Aim: This study investigates how researchers report ethical issues in the software engineering journal publications, particularly informed consent, confidentiality, and anonymity. Method: We conducted a literature review to understand the reporting of ethical issues in software engineering journals. In addition, in a workshop, we discussed the importance of reporting the different ethical issues. Results: The results indicate that 49 out of 95 studies reported some ethical issues. Only six studies discussed all three ethical issues. The subjects were mainly informed about the study purpose and procedure. There are limited discussions on how the subjects were informed about the risks involved in the study. Studies reported on how authors ensured confidentiality have also discussed anonymity in most cases. The results of the workshop discussion indicate that reporting ethical issues is important to improve the reliability of the research results. We propose a checklist based on the literature review, which we validated through a workshop. Conclusion: The checklist proposed in this paper is a step towards enhancing ethical reporting in software engineering research.

Konferensbidrag (refereegranskat)abstract
- Ethical guidelines of software engineering journals require authors to provide statements related to the conflict of interest and the process of obtaining consent (if human subjects are involved). The objective of this study is to review the reporting of the ethical considerations in Empirical Software Engineering - An International Journal. The results indicate that two out of seven studies reported some ethical information however, not explicitly. The ethical discussions were focussed on anonymity and confidentiality. Ethical aspects such as competence, comprehensibility and vulnerability of the subjects were not discussed in any of the papers reviewed in this study. It is important to not only state that consent was obtained however, the procedure of obtaining consent should be reported to improve the accountability and trust.

Towards decision-making to choose among different component origins
- 2016
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Context: The amount of software in solutions provided in various domains is continuously growing. These solutions are a mix of hardware and software solutions, often referred to as software-intensive systems. Companies seek to improve the software development process to avoid delays or cost overruns related to the software development. Objective: The overall goal of this thesis is to improve the software development/building process to provide timely, high quality and cost efficient solutions. The objective is to select the origin of the components (in-house, outsource, components off-the-shelf (COTS) or open source software (OSS)) that facilitates the improvement. The system can be built of components from one origin or a combination of two or more (or even all) origins. Selecting a proper origin for a component is important to get the most out of a component and to optimize the development. Method: It is necessary to investigate the component origins to make decisions to select among different origins. We conducted a case study to explore the existing challenges in software development. The next step was to identify factors that influence the choice to select among different component origins through a systematic literature review using a snowballing (SB) strategy and a database (DB) search. Furthermore, a Bayesian synthesis process is proposed to integrate the evidence from literature into practice. Results: The results of this thesis indicate that the context of software-intensive systems such as domain regulations hinder the software development improvement. In addition to in-house development, alternative component origins (outsourcing, COTS, and OSS) are being used for software development. Several factors such as time, cost and license implications influence the selection of component origins. Solutions have been proposed to support the decision-making. However, these solutions consider only a subset of factors identified in the literature. Conclusions: Each component origin has some advantages and disadvantages. Depending on the scenario, one component origin is more suitable than the others. It is important to investigate the different scenarios and suitability of the component origins, which is recognized as future work of this thesis. In addition, the future work is aimed at providing models to support the decision-making process.

Improving Internal Software Reuse in the Context of Contemporary Software Engineering Practices
- 2023
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Context: Companies adopt many software reuse practices, such as software product line, reuse verbatim, and systematic reuse, to improve their internal software development and maximize the benefits. Contemporary software engineering (SE) practices, such as microservices and InnerSource, influence internal software reuse.Objective: In this thesis, we aim to improve internal software reuse in the context of contemporary SE practices. To do that, we want to 1) understand the state-of-the-art and the state-of-the-practice of software reuse costs and benefits and the challenges that companies are currently facing and 2) identify interventions to improve internal software reuse. Methods: We conducted a systematic literature review to understand the state-of-the-art of software reuse costs and benefits. We performed two exploratory case studies to understand the state-of-the-practice of software reuse costs and benefits, challenges, and improvement areas in the context of contemporary SE practices. We performed another follow-up improving case study to investigate the medium-sized case company's readiness of adopting InnerSource for software reuse.Results: Existing literature reported more software reuse benefits than costs. The most reported software reuse benefits are better product quality and improved productivity. Verbatim reuse and systematic reuse result in more reuse benefits. Most of the included primary studies are of moderate quality, with only four having high quality. Practitioners think that software reuse costs in developing reusable assets will be paid off when developers start to reuse them. Challenges in software reuse in the context of contemporary SE practices differ between medium-sized and large-sized companies. Both of the companies perceive that InnerSource can help improve internal software reuse. Asking practitioners about both current and desired InnerSource reuse status helps identify the needed InnerSource improvements, thus helping companies succeed in adopting InnerSource for reuse. Conclusion: Both existing literature and our two case studies investigating software reuse in the context of contemporary SE practices showed that software reuse improves quality and productivity and has costs in developing and integrating reusable assets. However, the overall benefits outweigh the costs. Both case companies faced challenges in improving their internal reuse, where the most common challenges were about developing and maintaining reusable assets. The results showed that InnerSource helps develop and maintain reusable assets and further improves internal software reuse.

Tidskriftsartikel (refereegranskat)abstract
- Background: Software practice is evolving with changing technologies and practices such as InnerSource, DevOps, and microservices. It is important to investigate the impact of contemporary software engineering (SE) practices on software reuse.Aim: This study aims to characterize software reuse in contemporary SE practices and investigate its implications in terms of costs, benefits, challenges, and potential improvements in a medium-sized company.Method: We performed an exploratory case study by conducting interviews, group discussions, and reviewing company documentation to investigate software reuse in the context of contemporary SE practices in the case company.Results: The results indicate that the development for reuse in contemporary SE practices incurs additional coordination, among other costs. Development with reuse led to relatively fewer additional costs and resulted in several benefits such as better product quality and less development and delivery time. Ownership of reusable assets is challenging in contemporary SE practice. InnerSource practices may help mitigate the top perceived challenges: discoverability and ownership of the reusable assets, knowledge sharing and reuse measurement.Conclusion: Reuse in contemporary SE practices is not without additional costs and challenges. However, the practitioners perceive costs as investments that benefit the company in the long run.

Understanding and Evaluating Software Reuse Costs and Benefits from Industrial Cases - A Systematic Literature Review
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Companies adopt various software reuse practices to achieve more benefits. Existing secondary studies aggregated primary evidence on software reuse benefits more than the costs. It is important to know how the software reuse costs and benefits are measured and the strength of the evidence. This study aims to conduct a systematic literature review to identify the observed software reuse costs and benefits from industrial cases and investigate how the identified software reuse costs and benefits are measured. In addition, we also assess the quality of the included primary studies to understand the strength of evidence behind the identified software reuse costs and benefits. We included 30 primary studies on software reuse costs and benefits in industrial cases using a mixed search strategy - automated search and snowballing. We identified nine software reuse benefits, six software reuse costs, and the metrics used to measure them. Better quality and improved productivity are the most investigated software reuse benefits, and most primary studies that report these two benefits are of good or moderate quality. Few primary studies reported software reuse costs, and most of them are of low quality. Generally, the quality of primary studies reporting software reuse benefits is better than those reporting software reuse costs.

Understanding and evaluating software reuse costs and benefits from industrial cases—A systematic literature review
- 2024
-
Ingår i: Information and Software Technology. - : Elsevier. - 0950-5849 .- 1873-6025. ; 171
-
Forskningsöversikt (refereegranskat)abstract
- Context: Software reuse costs and benefits have been investigated in several primary studies, which have been aggregated in multiple secondary studies as well. However, existing secondary studies on software reuse have not critically appraised the evidence in primary studies. Moreover, there has been relatively less focus on how software reuse costs and benefits were measured in the primary studies, and the aggregated evidence focuses more on software reuse benefits than reuse costs. Objective: This study aims to cover the gaps mentioned in the context above by synthesizing and critically appraising the evidence reported on software reuse costs and benefits from industrial cases. Method: We used a systematic literature review (SLR) to conduct this study. The results of this SLR are based on a final set of 30 primary studies. Results: We identified nine software reuse benefits and six software reuse costs, in which better quality and improved productivity were investigated the most. The primary studies mostly used defect-based and development time-based metrics to measure reuse benefits and costs. Regarding the reuse practices, the results show that software product lines, verbatim reuse, and systematic reuse were the top investigated ones, contributing to more reuse benefits. The quality assessment of the primary studies showed that most of them are either of low (20%) or moderate (67%) quality. Conclusion: Based on the number and quality of the studies, we conclude that the strength of evidence for better quality and improved productivity as reuse benefits is high. There is a need to conduct more high quality studies to investigate, not only other reuse costs and benefits, but also how relatively new reuse-related practices, such as InnerSource and microservices architecture, impact software reuse. © 2024 The Author(s)

Konferensbidrag (refereegranskat)abstract
- Background: InnerSource consists of the use of open source development techniques within the corporation. It helps improve software reuse through increased transparency and inter-team collaboration. Companies need to understand their context and specific needs before deciding to adopt any specific InnerSource practices since they cannot apply all InnerSource practices at once. Aim: This study aims to support the case company in assessing its readiness for adopting InnerSource practices to improve its internal reuse, identify and prioritize the improvement areas, and identify suitable solutions. Method: We performed a case study using a questionnaire and a workshop to check the current and desired status of adopting InnerSource practices and collect potential solutions. Results: The study participants identified that the company needs to prioritize the improvements related to the discoverability, communication channels, and ownership of the reusable assets. In addition, they identified certain InnerSource practices as solutions for the prioritized improvement areas, such as better structured repositories for storing and searching the reusable assets and standardized documentation of the reusable assets. Conclusion: The questionnaire instrument aids the case company in identifying the improvement areas related to InnerSource and reuse practices. InnerSource practices could improve the development and maintenance of reusable assets. Keywords: InnerSource, software reuse, readiness © 2023 Owner/Author.

Towards automated open source assessment - An empirical study
- 2022
-
Ingår i: CEUR Workshop Proceedings. - : Technical University of Aachen.
-
Konferensbidrag (refereegranskat)abstract
- The open source software (OSS) assessment has become important given the increased adoption of OSS in commercial product development. Researchers proposed many OSS assessment models. However, little is known about the industrial relevance of the models. In this study, we proposed an automated tool based on the OSS assessment attributes identified together with a European cloud provider company. We analyzed 51 repositories to observe patterns in maintenance activities over their lifetime (from inception to the latest release). Based on the analysis, we propose a novel approach for evaluating the maturity of the OSS project. Finally, we assessed the usefulness of our automated solution in a pilot study. © 2022 Copyright for this paper by its authors.

Context factors perceived important when looking for similar experiences in decision-making for software components : An interview study
- 2024
-
Ingår i: Journal of Software. - : John Wiley & Sons. - 2047-7473 .- 2047-7481.
-
Tidskriftsartikel (refereegranskat)abstract
- During software evolution, decisions related to components' origin or source significantly impact the quality properties of the product and development metrics such as cost, time to market, ease of maintenance, and further evolution. Thus, such decisions should ideally be supported by evidence, i.e., using previous experiences and information from different sources, even own previous experiences. A hindering factor to such reuse of previous experiences is that these decisions are highly context-dependent and it is difficult to identify when previous experiences come from sufficiently similar contexts to be useful in a current setting. Conversely, when documenting a decision (as a decision experience), it is difficult to know which context factors will be most beneficial when reusing the experience in the future. An interview study is performed to identify a list of context factors that are perceived to be most important by practitioners when using experiences to support decision-making for component sourcing, using a specific scenario with alternative sources of experiences. We observed that the further away (from a company or an interviewee) the experience evidence is, as is the case for online experiences, the more context factors are perceived as important by practitioners to make use of the experience. Furthermore, we discuss and identify further research to make this type of decision-making more evidence-based. With this interview study, which focuses on which context factors are perceived as important by practitioners when reusing previous knowledge on software component reuse, we contribute with a listing of factors perceived to be important when reusing experiences from other prior decision-making cases of selecting among software components options. image

Choosing Component Origins for Software Intensive Systems: In-House, COTS, OSS or Outsourcing?-A Case Survey
- 2018
-
Ingår i: IEEE Transactions on Software Engineering. - : IEEE Computer Society. - 0098-5589 .- 1939-3520. ; 44:3, s. 237-261
-
Tidskriftsartikel (refereegranskat)abstract
- The choice of which software component to use influences the success of a software system. Only a few empirical studies investigate how the choice of components is conducted in industrial practice. This is important to understand to tailor research solutions to the needs of the industry. Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better. Interestingly, the final decision was perceived negatively in nine cases and positively in seven cases, while in the remaining cases it was perceived as neither positive nor negative.

-
Konferensbidrag (refereegranskat)abstract
- Context: Software testing requires substantial effort in maintaining GUI test scripts, leading to rework or waste. Therefore, it is important to identify the factors leading to waste in GUI-based automation testing. Objective: To identify testability requirements and factors associated with waste from literature and practice. Methods: We conducted a literature review to identify the state of knowledge and a two-phased interview with practitioners to capture their subjective opinions and gather their views on the state of knowledge. Results: We identified 16 testability requirements and 14 factors associated with waste in GUI test automation. We classified each of them into SUT-related, test-process-related, test-tool-related, human and organizational, environment and cross-cutting. Conclusions: Our results indicate that the generic testability requirements identified in the literature are also valid for GUI automation testing. Our study identifies new findings in addition to the existing literature. © 2022 Owner/Author.

Konferensbidrag (refereegranskat)abstract
- Kubernetes is a free, open-source container orchestration system for deploying and managing Docker containers that host microservices. Kubernetes cluster logs help in determining the reason for the failure. However, as systems become more complex, identifying failure reasons manually becomes more difficult and time-consuming. This study aims to identify effective and efficient classification algorithms to automatically determine the failure reason. We compare five classification algorithms, Support Vector Machines, K-Nearest Neighbors, Random Forest, Gradient Boosting Classifier, and Multilayer Perceptron. Our results indicate that Random Forest produces good accuracy while requiring fewer computational resources than other algorithms. © 2023 Owner/Author.

Effective reviews require an in-depth understanding of the code and demand from the reviewers to contextualize the change from different perspectives.Aim: While there is a plethora of research on solutions that support developers to understand changed code, we have observed that many provide only narrow, specialized insights and very few aggregate information in a meaningful manner. Therefore, we aim to provide a vision of improving code understanding in MCR.Method: We classified 53 research papers suggesting proposals to improve MCR code understanding. We use this classification, the needs expressed by code reviewers from previous research, and the information we have not found in the literature for extrapolation.Results: We identified four major types of support systems and suggest an environment for contextualized code reviews. Furthermore, we illustrate with a set of scenarios how such an environment would improve the effectiveness of code reviews.Conclusions: Current research focuses mostly on providing narrow support for developers. We outline a vision for how MCR can be improved by using context and reducing the cognitive load on developers. We hope our vision can foster future advancements in development environments. © 2024 Copyright is held by the owner/author(s). Publication rights licensed to ACM.

Tidskriftsartikel (refereegranskat)abstract
- This article presents an ecosystem that Ericsson developed to systematically practice large-scale reuse of microservices in a cloud-native context. We discuss how various ecosystem aspects, such as its continuous delivery mechanism, marketplace, and automated checking of design rules, facilitated the development and reuse of microservices across Ericsson. We also share lessons learned while developing the ecosystem including the initiatives related to the adoption of InnerSource practices for sustaining the ecosystem.
