Thesis
Full-text available
Agile methods have in recent years become common in software development projects. The daily stand-up meeting (DSM) is the most used agile practice, but the practice has garnered scant research attention. On the basis of four case studies and one grounded theory study, this thesis explores how the DSM is used and perceived by members of agile softw...

Context: Most of the software organizations that use agile methods organize daily team meetings. Aim: Our aim was to understand how daily meetings are conducted and identify obstacles that reduce their efficiency. Method: We observed 56 daily meetings and conducted 21 interviews in three different teams in two countries. We used the repertory grid...

An increasing amount of time is being spent at organizational meetings. One common type of meeting in software projects is the daily team meeting, which is the most important forum for coordinating and planning daily work. To better understand how software teams make decisions, communicate, and coordinate their work, we must uncover the micro-level...

Escalating commitment is a common and costly phenomenon in software projects in which decision-makers continue to invest resources to a failing course of action. We conducted a longitudinal case study exploring the effect of daily meetings on escalating commitment. This was done in an agile project building software for the oil and gas industry. By...

Agile software development has become the standard in many companies. While there are reports of major improvements with agile development over traditional development, many teams still strive to work effectively as a team. A multiple case study in two companies discovered challenges related to communication, learning and selecting the tasks accord...
Article
Over the last two decades, agile software development has gained popularity among software engineering researchers and practitioners. However, the development and use of theories in agile research remain relatively low. While analyzing publications on agile software development in the Scopus database from the last decade, we found that only 7% of t...

Today, many companies allow their employees to work from anywhere, which has changed how employees coordinate their work and align toward the same goals. Objectives and Key Results (OKRs) is a goal-setting framework applied in such distributed settings. This research aimed to investigate how OKRs are used in large-scale agile contexts. We interview...
Article
Large-scale transformations of agile ways of working have received more attention in the industry in recent years. Some organizations have developed their own solutions for scaling, whereas many have chosen trademarked frameworks. In large-scale agile software development, many developers and development teams carry out work simultaneously. When au...

Software development companies organize hackathons to encourage innovation. Despite many benefits of hackathons, in large-scale agile organizations where many teams work together, stopping the ongoing work results in a significant decrease in the immediate output. Motivated by the need to understand whether and how to run hackathons, we investigate...

Agile transformation implies that organizations apply agile methods also outside of software development units. One particular way of doing such transformations is to create cross-functional software development units. This represents new challenges for control for organizations as the unformal agile control mechanisms from the software units meet...
