Given software's important role in business, the design of effective development processes has received great attention. Early attempts at standardizing a formal software development model culminated in what's now known as the waterfall model. Over time, this view of software development as a process that could be managed proactively led to the development of other models, each proposing improvements. However, although some of the practices in these newer models complement the waterfall model, others appear to contradict its main principles. Furthermore, the performance dimensions that each practice seeks to optimize often differ. Unfortunately, these potential conflicts are difficult to resolve because the data presented to support most models is anecdotal and biased toward reporting only successful projects. Our objective here is to look at how certain practices, proposed by various development models, affect performance. By exploring different practices' associations with multiple dimensions of performance across a number of projects, we examine the trade-offs involved in designing a process to optimize specific performance criteria. We carefully selected the practices for investigation to explore some of the potential conflicts that arise between different development models.

Background: Agile software development has been around for almost 20 years and it is now mainstream. Many companies claim to be agile but what that really means is not clear. There is a wide scope of software engineering practices in use nowadays, some are technical and some organizational, and some are agile and some are not agile at all. Objective: In this study we aim to understand the influence o f A gile in the set of practices that are currently in use in the software industry. Method: The data from HELENA Survey, a large-scale international initiative, was analyzed. Results: The practices with higher usage rate are strongly related to Agile, some of them were introduced by agile methods while others are pre-agile. Those that were introduced by agile methods are mainly organizational practices, while those that are pre-agile are mainly technical practices. Conclusion: The main usage of agile nowadays in software development is related to people and work organization;and the most popular technical practices are those pre-agile practices that were included in the agile methods.

Lifting the Curtain on Merge Conflict Resolution: A Sensemaking Perspective 36

Merge conflicts are an inevitable, but painful part of collaborative software development. Merge conflict resolution is nontrivial because it requires gathering information from disparate sources (e.g., a codebase, diffs between versions, history of changes, documentation etc.) and then piecing together not only this information, but the rationale and context behind the conflicting changes. Current tools offer inadequate support to developers trying to understand the context and impact of the conflicting changes. They also offer little support in evaluating potential resolutions. To improve conflict resolution tools, we first need to understand the information needs of conflict resolution and its underlying sensemaking process. In this paper, through in-situ observations of 10 conflict resolutions, we qualitatively investigate how developers collect and sensemake different conflict-related information and how they reach a resolution. We identified eight behaviour patterns that developers use. These patterns have implications for tool builders and developers alike. We identify specific areas that need improved tool support. We also highlight the sensemaking traps practitioners may fall into.

We apply the biological-behavioral concept of an umwelt, which is how an organism perceives and acts within its environment, to the practice of software development. By writing narrative descriptions of our own software umwelts and iteratively discussing and analyzing them, we develop prompts that can elicit reflection on how and why we relate to software in the ways that we do.

Small and medium-sized enterprises (SMEs) play a key role in the worldwide economy and are increasingly dependent on software as part of their products/services or to support their operation (e.g. e-commerce, smart manufacturing). Over the past 15 years, as a research and technology transfer centre, CETIC has been busy helping Belgian SMEs to increase their maturity in software development. We have also contributed specific methods and tools for the SME target, including the OWPL framework and now the IS029110 standard. This talk aims at sharing what we learned from different types of SMEs (from startups to grownups, both IT and non IT) about common problems gathered in a long term survey. We then focus on key issues like requirements, technical debt, test/release and (agile/lean) project management. Finally, we share our thoughts on new challenges ahead raised by the ever increasing connectivity like cybersecurity and privacy regulation (GDPR).

Numerous software development practices suggest updating the test code whenever the production code is changed. However, previous studies have shown that co-evolving test and production code is generally a difficult task that needs to be thoroughly investigated. In this paper we perform a study that, following a mixed methods approach, investigates fine-grained co-evolution patterns of production and test code. First, we mine fine-grained changes from the evolution of 5 open-source systems. Then, we use an association rule mining algorithm to generate the co-evolution patterns. Finally, we interpret the obtained patterns by performing a qualitative analysis. The results show 6 co-evolution patterns and provide insights into their appearance along the history of the analyzed software systems. Besides providing a better understanding of how test code evolves, these findings also help identify gaps in the test code thereby assisting both researchers and developers.

Manifestos are often a vehicle to trigger change by catalyzing discussion around a core group of ideas and values - and there is no doubt that the publication of the "Agile Manifesto" in 2001 increased visibility for an emergent breed of lightweight software practices. The panel discussed how the Agile Manifesto has impacted academic and industry software professionals in the areas of culture, education, and software practices.

Many prescriptive approaches to developing software intensive systems have been advocated but each is based on assumptions about context. It has been found that practitioners do not follow prescribed methodologies, but rather select and adapt specific practices according to local needs. As researchers, we would like to be in a position to support such tailoring. However, at the present time we simply do not have sufficient evidence relating practice and context for this to be possible. We have long understood that a deeper understanding of situated software practices is crucial for progress in this area, and have been exploring this problem from a number of perspectives. In this position paper, we draw together the various aspects of our work into a holistic model and discuss the ways in which the model might be applied to support the long term goal of evidence-based decision support for practitioners. The contribution specific to this paper is a discussion on model evaluation, including a proof-of-concept demonstration of model utility. We map Kernel elements from the Essence system to our model and discuss gaps and limitations exposed in the Kernel. Finally, we overview our plans for further refining and evaluating the model.

There has been a recent increase in the use of agile coaches in organizations. Although the use of the job title is popular, empirical knowledge about the tasks, responsibilities and skills of an agile coach is lacking. In this paper, we present a systematic literature review on agile coaching and the role of the agile coach. The initial search resulted in a total of 209 studies identified on the topic. Based on our inclusion and exclusion criteria, a total of 67 studies were selected as primary studies. Our findings suggest that agile coaching facilitates the adoption and sustainability of agile methods and deals with agile adoption challenges. Agile coaches help in training and developing software development teams and all the stakeholders involved in the agile adoption process. The primary skills of an agile coach identified herein are leadership qualities, project management skills, technical skills, and expertise in agile methods. Based on the findings, it can be argued that agile coaches play a significant role in addressing challenges in an agile transformation such as resistance to change. Coaches focus on removing barriers to team autonomy in agile teams and making agile meetings more valuable.
