Context factors perceived important when looking for similar experiences in decision-making for software components : An interview study
- 2024
-
In: Journal of Software. - : John Wiley & Sons. - 2047-7473 .- 2047-7481.

Journal article (peer-reviewed)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

Towards evidence-based decision-making for identification and usage of assets in composite software : A research roadmap
- 2021
-
In: Journal of Software. - : John Wiley and Sons Ltd. - 2047-7473 .- 2047-7481. ; 33:6

Journal article (peer-reviewed)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.

Agile Processes in Software Engineering and Extreme Programming
- 2012
-
Editorial collection (other academic/artistic)abstract
- This book contains the refereed proceedings of the 13th International Conference on Agile Software Development, XP 2012, held in Malmö, Sweden, in May 2011. In the last decade, we have seen agile and lean software development strongly influence the way software is developed. Agile and lean software development has moved from being a way of working for a number of pioneers to becoming, more or less, the expected way of developing software in industry. The topics covered by the selected full papers include general aspects of agility, agile teams, studies related to the release and maintenance of software, and research on specific practices in agile and lean software development. They are complemented by four short papers capturing additional aspects of agile and lean projects.

State-of-the-art: software inspections after 25 years
- 2002
-
In: Software Testing, Verification & Reliability. - : Wiley. - 0960-0833 .- 1099-1689. ; 12:3, s. 133-154
-
Journal article (peer-reviewed)abstract
- Software inspections, which were originally developed by Michael Fagan in 1976, are an important means to verify and achieve sufficient quality in many software projects today. Since Fagan's initial work, the importance of software inspections has been long recognized by software developers and many organizations. Various proposals have been made by researchers in the hope of improving Fagan's inspection method. The proposals include structural changes to the process and several types of support for the inspection process. Most of the proposals have been empirically investigated in different studies. This is a review paper focusing on the software inspection process in the light of Fagan's inspection method and it summarizes and reviews other types of software inspection processes that have emerged in the last 25 years. This paper also addresses important issues related to the inspection process and examines experimental studies and their findings that are of interest with the purpose of identifying future avenues of research in software inspection.

A decision-making process-line for selection of software asset origins and components
- 2018
-
In: Journal of Systems and Software. - : Elsevier Inc.. - 0164-1212 .- 1873-1228. ; 135, s. 88-104

Journal article (peer-reviewed)abstract
- 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.

Software product quality in global software development : Finding groups with aligned goals
- 2011
-
In: 37th EUROMICRO Conference on Software Engineering and Advanced Applications (SEAA 2011). - Oulu : IEEE Computer Society. - 9781457710278 ; , s. 435-442

Conference paper (peer-reviewed)abstract
- The development of a software product in an organization involves various groups of stakeholders who may prioritize the qualities of the product differently. This paper presents an empirical study of 65 individuals in different roles and in different locations, including on shoring, outsourcing and off shoring, prioritizing 24 software quality aspects. Hierarchical cluster analysis is applied to the prioritization data, separately for the situation today and the ideal situation, and the composition of the clusters, regarding the distribution of the inherent groupings within each of them, is analyzed. The analysis results in observing that the roles are not that important in the clustering. However, compositions of clusters regarding the onshore-offshore relationships are significantly different, showing that the offshore participants have stronger tendency to cluster together. In conclusion, stakeholders seem to form clusters of aligned understanding of priorities according to personal and cultural views rather than their roles in software development.

Stakeholders’ Perception of Success: an Empirical Investigation
- 2009
-
In: SEAA '09. 35th Euromicro Conference on Software Engineering and Advanced Applications, 2009.. - Patras, Greece : Euromicro. - 1089-6503. - 9780769537849 ; , s. 210-216
-
Conference paper (peer-reviewed)abstract
- Different stakeholders involved in the software development may attribute success to different indicators. Analogously they may support different factors considered the root of successful projects. The study presented in this paper explores how different stakeholders perceive project success and what they deem the effect of specific factors on the project outcome. The study highlighted both commonalities and differences among three main stakeholder classes. A substantial agreement was observed concerning the characteristics that make a project or product successful. As far as the factors that could lead to success are concerned, more bias emerged.

Experimental context classification: incentives and experience of subjects
- 2005
-
In: 27th International Conference on Software Engineering. ; , s. 470-478
-
Conference paper (peer-reviewed)abstract
- There is a need to identify factors that affect the result of empirical studies in software engineering research. It is still the case that seemingly identical replications of controlled experiments result in different conclusions due to the fact that all factors describing the experiment context are not clearly defined and hence controlled. In this article, a scheme for describing the participants of controlled experiments is proposed and evaluated. It consists of two main factors, the incentives for participants in the experiment and the experience of the participants. The scheme has been evaluated by classifying a set of previously conducted experiments from literature. It can be concluded that the scheme was easy to use and understand. It is also found that experiments that are classified in the same way to a large extent point at the same results, which indicates that the scheme addresses relevant factors

Pair-wise comparisons versus planning game partitioning-experiments on requirements prioritisation techniques
- 2007
-
In: Empirical Software Engineering. - : Springer Science and Business Media LLC. - 1573-7616 .- 1382-3256. ; 12:1, s. 3-33
-
Journal article (peer-reviewed)abstract
- The process of selecting the right set of requirements for a product release is dependent on how well the organisation succeeds in prioritising the requirements candidates. This paper describes two consecutive controlled experiments comparing different requirements prioritisation techniques with the objective of understanding differences in time-consumption, ease of use and accuracy. The first experiment evaluates Pair-wise comparisons and a variation of the Planning game. As the Planning game turned out as superior, the second experiment was designed to compare the Planning game to Tool-supported pair-wise comparisons. The results indicate that the manual pair-wise comparisons is the most time-consuming of the techniques, and also the least easy to use. Tool-supported pair-wise comparisons is the fastest technique and it is as easy to use as the Planning game. The techniques do not differ significantly regarding accuracy.
