Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)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.

Alignment of Software Product Quality Goals in Two Outsourcing Relationships
- 2010
-
Ingår i: 14th International Conference on Evaluation and Assessment in Software Engineering (EASE). - Keele, UK : British Informatics Society Ltd..

Konferensbidrag (refereegranskat)abstract
- Background: Issues with software product quality are commonly reported when organisations engage in outsourcing relationships. To address this issue, value-based software engineering literature emphasises the need for all success-critical stakeholder groups to work towards a mutually agreed goal. Aim: This paper presents a case study that aims to compare and contrast the priority two groups place on software product quality — stakeholders internal to the development organisation, and stakeholders from outsourcing relationships. Method: A model of software product quality was developed and used for this study based on ISO 9126 standard. Questionnaires were collected from 38 representatives of the two key stakeholder groups, in which each person rates the relative importance of aspects of software product quality using the hierarchical cumulative voting (HCV) technique. The results of these two groups were then analysed and compared. Results: The results show the stakeholders priorities to be a merging of the priorities from both the software development organsiation, and the firm providing the outsourced services. Further, stakeholders from outsourced relationships had greater difficulty define an ideal future balance of software product qualities. Conclusions: One of the keys to success when outsourcing is to ensure both the internal and external groups understand the needs of each other — and ensure they can work towards a sufficiently compatible goal. It may be necessary to change the way work is outsourced to align the goals of both firms to be compatible.

Offshore insourcing : A case study on software quality alignment
- 2011
-
Ingår i: 2011 IEEE Sixth International Conference on Global Software Engineering. - Helsinki : IEEE. - 9781457711404 - 9780769545035 ; , s. 146-155

Konferensbidrag (refereegranskat)abstract
- Background: Software quality issues are commonly reported when off shoring software development. Value-based software engineering addresses this by ensuring key stakeholders have a common understanding of quality. Aim: This work seeks to understand the levels of alignment between key stakeholders on aspects of software quality for two products developed as part of an offshore in sourcing arrangement. The study further aims to explain the levels of alignment identified. Method: Representatives of key stakeholder groups for both products ranked aspects of software quality. The results were discussed with the groups to gain a deeper understanding. Results: Low levels of alignment were found between the groups studied. This is associated with insufficiently defined quality requirements, a culture that does not question management and conflicting temporal reflections on the product's quality. Conclusion: The work emphasizes the need for greater support to align success-critical stakeholder groups in their understanding of quality when off shoring software development

- Context: Software quality issues are commonly reported when offshoring software development. Value-based software engineering addresses this by ensuring key stakeholders have a common understanding of quality.Objective: This work seeks to understand the levels of alignment between key stakeholder groups within a company on the priority given to aspects of software quality developed as part of an offshoring relationship. Furthermore, the study aims to identify factors impacting the levels of alignment identified.Method: Three case studies were conducted, with representatives of key stakeholder groups ranking aspects of software quality in a hierarchical cumulative exercise. The results are analysed using Spearman rank correlation coefficients and inertia. The results were discussed with the groups to gain a deeper understanding of the issues impacting alignment.Results: Various levels of alignment were found between the various groups. The reasons for misalignment were found to include cultural factors, control of quality in the development process, short-term versus long-term orientations, understanding of cost-benefits of quality improvements, communication and coordination.Conclusions: The factors that negatively affect alignment can vary greatly between different cases. The work emphasises the need for greater support to align company internal success-critical stakeholder groups in their understanding of quality when offshoring software development.

Alignment of business, architecture, process, and organisation in a software development context
- 2012
-
Konferensbidrag (refereegranskat)abstract
- In this paper we investigate the current state of work regarding alignment of Business, Architecture, Process, and Organisation (BAPO) perspectives in a software product development context. We planned to do that by conducting a systematic literature study to capture the state of the art in alignment of BAPO in software development. But, as it turned out we found that almost no substantial information is available about the alignment of BAPO in software development. Thus, based on the available literature and a small qualitative study, we defined a conceptual model of the alignment of BAPO including five levels of alignment that can be used as a basis for future empirical studies.

An Evolutionary Perspective on Socio-Technical Congruence:The Rubber Band Effect
- 2013
-
Ingår i: International Symposium on Empirical Software Engineering and Measurement. - Baltimore : IEEE Xplore.
-
Konferensbidrag (refereegranskat)abstract
- Conway’s law assumes a strong association between the system’s architecture and the organization’s communication structure that designs it. In the light of contemporary software development, when many companies rely on geographically distributed teams, which often turn out to be temporarily composed and thus having an often changing communication structure, the importance of Conway’s law and its inspired work grows. In this paper, we examine empirical research related to Conway’s law and its application for cross-site coordination. Based on the results obtained we conjecture that changes in the communication structure alone sooner or later trigger changes in the design structure of the software products to return the sociotechnical system into the state of congruence. This is further used to formulate a concept of a rubber band effect and propose a replication study that goes beyond the original idea of Conway’s law by investigating the evolution of socio-technical congruence over time.

A systematic literature review on the industrial use of software process simulation
- 2014
-
Ingår i: Journal of Systems and Software. - : Elsevier. - 0164-1212. ; 97
-
Tidskriftsartikel (refereegranskat)abstract
- Context Software process simulation modelling (SPSM) captures the dynamic behaviour and uncertainty in the software process. Existing literature has conflicting claims about its practical usefulness: SPSM is useful and has an industrial impact; SPSM is useful and has no industrial impact yet; SPSM is not useful and has little potential for industry. Objective To assess the conflicting standpoints on the usefulness of SPSM. Method A systematic literature review was performed to identify, assess and aggregate empirical evidence on the usefulness of SPSM. Results In the primary studies, to date, the persistent trend is that of proof-of-concept applications of software process simulation for various purposes (e.g. estimation, training, process improvement, etc.). They score poorly on the stated quality criteria. Also only a few studies report some initial evaluation of the simulation models for the intended purposes. Conclusion There is a lack of conclusive evidence to substantiate the claimed usefulness of SPSM for any of the intended purposes. A few studies that report the cost of applying simulation do not support the claim that it is an inexpensive method. Furthermore, there is a paramount need for improvement in conducting and reporting simulation studies with an emphasis on evaluation against the intended purpose.

Evidence-Based Timelines for Agile Project Retrospectives – A Method Proposal
- 2012
-
Ingår i: Agile Processes in Software Engineering and Extreme Programming/Lecture Notes in Business Information Processing. - Berlin, Heidelberg : Springer Berlin Heidelberg. - 9783642303494 ; 111:5, s. 177-184

- Retrospective analysis of agile projects can support identification of issues through team reflection and may enable learning and process improvements. Basing retrospectives primarily on experiences poses a risk of memory bias as people may remember events differently, which can lead to incorrect conclusions. This bias is enhanced in project retrospectives which cover a longer period compared to iteration retrospectives. To support teams in recalling accurate and joint views of projects, we propose using an evidence-based timeline with historical data as input to project retrospectives. The proposed method was developed together with a large software development company in the telecommunications domain. This paper outlines a method for visualizing an evidence-based project timeline by illustrating aspects such as business priority, iterations and test activities. Our method complements an experience-based approach by providing objective data as a starting point for reflection and aims to support objective analysis of issues and root causes.

Prioritization of issues and requirements by cumulative voting : A compositional data analysis framework
- 2010

Konferensbidrag (refereegranskat)abstract
- Cumulative Voting (CV), also known as Hundred-Point Method, is a simple and straightforward technique, used in various prioritization studies in software engineering. Multiple stakeholders (users, developers, consultants, marketing representatives or customers) are asked to prioritize issues concerning requirements, process improvements or change management in a ratio scale. The data obtained from such studies contain useful information regarding correlations of issues and trends of the respondents towards them. However, the multivariate and constrained nature of data requires particular statistical analysis. In this paper we propose a statistical framework; the multivariate Compositional Data Analysis (CoDA) for analyzing data obtained from CV prioritization studies. Certain methodologies for studying the correlation structure of variables are applied to a dataset concerning impact analysis issues prioritized by software professionals under different perspectives. These involve filling of zeros, transformation using the geometric mean, principle component analysis on the transformed variables and graphical representation by biplots and ternary plots.

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

Konferensbidrag (refereegranskat)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.
