- The digital infrastructure literature provides important perspectives on the intrinsic relations between information systems in today’s organisations. However, little attention has been paid to the challenges involved in providing requisite digital infrastructure services to organisations. In this paper, we argue digital infrastructure service providers operate in highly complex and uncertain environments. Rather than adopting a traditional approach to control, providers must therefore continuously negotiate a balance between control and drift as two complementary strategies. Our argument is based on a retrospective longitudinal case study of a Swedish infrastructure service team within a large international firm. Using the encounter-episode process model as structuring principle and focusing on the tension between control and drift, we analyse the evolution of the provider’s efforts to manage a portfolio of digital infrastructure services over a period of ten years. Based on these analyses, we uncover the involved complexities and dynamics, how control efforts and drift were constituted and how the infrastructure services were managed by continuously balancing control and drift. In conclusion, we relate the findings to extant literature to discuss new insights into provider management of digital infrastructure services. Copyright © 2019 Inderscience Enterprises Ltd.

- Current studies on User eXperience (UX) integration often do not investigate or reflect on the transition companies go through from only developing Graphical User Interfaces (GUI) to also considering usability and more recently UX. Understanding this transition provides a more holistic and realistic picture of integration and can be a rich source of knowledge for improving UX integration in the software industry. Applying case study and grounded theory research we show that UX integration, like other organizational changes, can include a mixture of planned and emergent initiatives, and is influenced by various intertwined events; not only those that reside inside an organization but also those external to it. We also show that different decisions that are made outside the authority of UX practitioners have an inevitable impact on enabling or prohibiting UX integration. In addition, we found that for a successful integration, practitioners need to explicitly consider and address the characteristics of UX, otherwise, the integration efforts may have a lopsided focus on the pragmatic aspect of UX, consequently, leave the hedonic aspect unaddressed. Based on our findings, we present four lessons learned and five pitfalls companies should consider to go beyond GUI design and usability to also address UX. (C) 2019 Published by Elsevier Inc.

- Several studies report that the use of model-centric methods in the automotive domain is widespread and offers several benefits. However, existing work indicates that few modelling frameworks explicitly include requirements engineering (RE), and that natural language descriptions are still the status quo in RE. Therefore, we aim to increase the understanding of current and potential future use of models in RE, with respect to the automotive domain. In this paper, we report our findings from a multiple-case study with two automotive companies, collecting interview data from 14 practitioners. Our results show that models are used for a variety of different purposes during RE in the automotive domain, e.g., to improve communication and to handle complexity. However, these models are often used in an unsystematic fashion and restricted to few experts. A more widespread use of models is prevented by various challenges, most of which align with existing work on model use in a general sense. Furthermore, our results indicate that there are many potential benefits associated with future use of models during RE. Interestingly, existing research does not align well with several of the proposed use cases, e.g., restricting the use of models to informal notations for communication purposes. Based on our findings, we recommend a stronger focus on informal modelling and on using models for multi-disciplinary environments. Additionally, we see the need for future work in the area of model use, i.e., information extraction from models by non-expert modellers.

- In the last decades, agile methods had a huge impact on how software is developed. In many cases, this has led to significant benefits, such as quality and speed of software deliv- eries to customers. However, safety-critical systems have widely been dismissed from benefiting from agile methods. Products that include safety critical aspects are therefore faced with a situation in which the development of safety-critical parts can significantly limit the potential speed-up through agile methods, for the full product, but also in the non-safety critical parts. For such products, the ability to develop safety-critical software in an agile way will generate a competitive advantage. In order to enable future research in this important area, we present in this paper a mapping of the current state of praxis based on a mixed method approach. Starting from a workshop with experts from six large Swedish product development companies we develop a lens for our analysis. We then present a systematic mapping study on safety-critical systems and agile development through this lens in order to map potential benefits, challenges, and solution candidates for guiding future research.

Adding value every sprint: A case study on large-scale continuous requirements engineering

Konferensbidrag (refereegranskat)abstract
- Agile development practices, such as continuous integration and continuous delivery, promise value through shorter time to market and increased exibility. While these practices have been widely adopted in small-scale, they have shown to be challenging to adopt in large-scale, system development. This is often due to a distance between customer and developer in large scale systems, and the need to break down value from the whole system into manageable parts. The notion of value is fundamental for agile methods, especially for practices such as continuous delivery to the customer. However, how value should be handled in development practices is not clearly understood. In this paper, we investigate how the notion of adding value in every sprint has been perceived in a large-scale system development. Based on an exploratory qualitative case study, the outcome shows that it is perceived beneficial by practitioners although it comes at a price and challenges exist.

Integrating User eXperience practices into software development processes: implications of the UX characteristics

Tidskriftsartikel (refereegranskat)abstract
- User eXperience (UX) is a key factor in the success of software systems. Many software companies face challenges in their work with UX. Existing research does not analyze UX practices and challenges in relation to other software quality characteristics or, in particular, in relation to usability. A better understanding of these challenges can help researchers and practitioners better address them in the future. In this empirical study, we have interviewed 17 practitioners with different backgrounds and occupations from eight software development companies. Their responses are coded, and analyzed with thematic analysis. We report eight themes of challenges that practitioners face in their work with UX. While some of these challenges partly overlap with those reported in existing literature about usability or other software quality characteristics, the participants of our study either view many of the challenges as unique to UX, or more severe in the case of UX. Although at a superficial level challenges of x and other quality characteristics overlap, we differentiate these challenges at a deeper level through the five main characteristics of i UX: subjective, holistic, dynamic, context dependent and worthwhile. In particular, we dentified that these characteristics have at least 20 implications (i.e.' additional difficulties) for day-to-day work of practitioners. We found that 11 of these implications have been previously reported in literature, However to the best of our knowledge, the remaining nine implications are unique to our study. These implications can explain why practitioners perceive the challenges to be more severe than for other quality characteristics. Most importantly, they l can explain the industry's lopsided focus on the pragmatic aspect of UX. Our findings can be useful for researchers in identifying new and industry-relevant re search areas and for practitioners to learn from empirically investigated challenges. UX work, and base their improvement efforts on such knowledge. Identifying and investigating the overlaps underlines the importance of these challenges, and can also help finding research areas not only for enhancing UX work but also software quality in general. It also (makes it easier for practitioners to spot, better understand as well as find mitigation strategies for UX, through learning from past experiences and developments in the area of software quality.

- User eXperience (UX) is becoming increasingly important for success of software products. Yet, many companies still face various challenges in their work with UX. Part of these challenges relate to inadequate knowledge and awareness of UX and that current UX models are commonly not practical nor well integrated into existing Software Engineering (SE) models and concepts. Therefore, we present a conceptual UX-aware model of requirements for software development practitioners. This layered model shows the interrelation between UX and functional and quality requirements. The model is developed based on current models of UX and software quality characteristics. Through the model we highlight the main differences between various requirement types in particular essentially subjective and accidentally subjective quality requirements. We also present the result of an initial validation of the model through interviews with 12 practitioners and researchers. Our results show that the model can raise practitioners’ knowledge and awareness of UX in particular in relation to requirement and testing activities. It can also facilitate UX-related communication among stakeholders with different backgrounds.

- We performed a retrospective meeting at a case company to reflect on its decade of Software Process Improvement (SPI) activities for enhancing UX integration. We supported the meeting by a pre-generated timeline of the main activities. This approach is a refinement of a similar approach that is used in Agile projects to improve effectiveness and decrease memory bias of retrospective meetings. The method is evaluated through gathering practitioners' view using a questionnaire. We conclude that UX research and practice can benefit from the SPI body of knowledge. We also argue that a cross-section evidence-based timeline retrospective meeting is useful for enhancing UX work in companies, especially for identifying and reflecting on `organizational issues'. This approach also provides a cross-section longitudinal overview of the SPI activities that cannot easily be gained in other common SPI learning approaches.

- In a day and age when contemporary businesses are transformed, driven by a service-dominance logic and dependent upon IT, we need to understand how firms cope with technological adaptations and how such technological adaptations can lead to service adaptations. Drawing on a framework on technological transitions and an interpretive longitudinal case study of the services provided by a team within a large public IT firm, this article addresses the following questions：How do service transitions come about? Can we distinguish particular patterns in service transition processes? This research unveils how technological and social dimensions mutually constitute each other within development and implementation of service provisioning. The findings show how：(a) IT plays a fundamental role in service provisioning; (b) technological transitions are the necessary but insufficient preconditions for service transitions; and (c) there are attenuation effects when it comes to the move from technology transition to service transition.
