Knowledge is a core resource for agile organisations that is transformed into products and services during the development process. Sharing of knowledge is essential across any organisation, and it has been claimed that the software industry requires more knowledge management than any other sector. Agile methodologies concentrate on team level coll...

The practice of making new software available to end users as soon as it gets implemented is becoming commonplace. This paper investigates a set of projects and their development practices in a mid-sized Finnish software company Solita Ltd. to understand how continuous deployment practices are applied in development teams. This was done by establis...

Agile software development processes (Agile), such as Scrum, DSDM, XP and Kanban, have become de facto standards for software development practice. Scrum, the most commonly used process, focuses on delivering functioning software early and continuously, and emphasizes speed, communication and developer collaboration in the software development proc...

In this chapter, we compare UX assessments of users and agile team members to learn to what extent developers can predict how users experience (UX) the product the developers are working on, and where user involvement is truly required. We compared UX assessments of agile team members (N = 26) and users (N = 29) of six enterprise applications with...

Most research on Agile UCD recommends scheduling of UX work one iteration ahead of development. There is, however, some evidence arguing for an approach where software developers and UX specialists work in cross-functional teams conducting design and implementation tasks during the present iteration. This within-iteration approach can, for instance...

Stakeholder involvement is one of the major success factors in integrating user experience (UX) practices into software development processes and organizations. It is also a necessity for agile software development. However, practitioners still have limited access to guidelines on successful involvement of UX stakeholders in agile settings. Moreove...

Background: Most companies practicing Agile are not fully Agile but instead they combine both Agile and traditional practices in their operations. It is not clear how these practices can be successfully used together in an organisation. Aims: We investigate practitioners' mitigation strategies related to the challenge of doing Agile in a non-Agile...

Software developers use software products to design and develop new software products for others to use. Research has introduced a concept of developer experience inspired by the concept of user experience but appreciating also the special characteristics of software development context. It is unclear what the experiential components of developer e...

Startups operate with small resources in time pressure. Thus, building minimal product versions to test and validate ideas has emerged as a way to avoid wasteful creation of complicated products which may be proven unsuccessful in the markets. Often, design of these early product versions needs to be done fast and with little advance information fr...

Software developers are both users of development tools but also designers of new software systems. This dual role makes developers special users of work-related software. To increase the understanding of developers as users and to evaluate the ability of common measurement scales to address developer experience, we conducted a survey measuring dev...

Startups often begin with minimal product versions to test and validate their product ideas as early as possible. Therefore, the first versions of the product need to be able to communicate the product idea to users in order to receive meaningful feedback. However, if user experience (UX) of the product is poor, users tend to concentrate on the dis...

Agile development methodologies have become the norm in software development. Simultaneously, user experience (UX) has become an increasingly important factor in the success or failure of software systems. However, agile methodologies do not give guidance on how to conduct UX work. Companies encounter challenges in UX work despite the previous acad...

Refactoring has been defined as improving code quality without affecting its functionality. When refactoring is overlooked in daily development, the likelihood of larger refactorings increases with time. Disadvantages of larger refactorings include that they disrupt the daily work, require additional planning effort, and often they need to be justi...

Synchronizing efforts between developers and user experience (UX) specialists is one of the major challenges in agile UX work. In this paper, we report results of a study period over a release cycle in six agile software development projects of five companies considering the task allocation and cooperation in the team. Team members (N = 31) includi...

Continuous approaches for software engineering such as continuous planning, development, and operations are becoming increasingly popular in agile software companies. It means that also user-centered design practitioners and practices need to adapt to both possibilities and challenges the increasingly rapid and more tightly integrated software engi...

We also observed changes in the organiza...

Abstract—Mobile apps form a special domain for designing user experience (UX). Interactions with the device should be designed such that the time span of the users' actions is shorter than in the desktop space; actions must be simple yet focused. Moreover, interactions must be accomplished with ease, using only a minimal number of finger presses or...

In the past years, people have started to use social media to interact actively about TV content. However, despite of over a decade of active research and product development, Social TV has not been adopted by large populations. This paper aims to support designing interaction for Social TV services and, more specifically, designing for the presenc...

The ways people consume content and use applications with different types of devices are fundamentally different. When designing applications for enterprise use, user experience (UX) must typically be addressed during the upfront design of the application. Due to the importance of upfront design regarding UX, the product owner (PO), responsible for...

While Agile methods were originally introduced for small, tightly coupled teams, leaner ways of working are becoming a practical method to run entire enterprises. As the emphasis of user experience work has inherently been on the early phases before starting the development, it also needs to be adapted to the Agile way of working. To improve the cu...

Many companies have been conducting their software development activities using Agile methods for years; however, in many cases the management and sales processes of these companies are still run in a more traditional way. This can cause clashes between development and management; and especially in terms of user experience specialists, who are ofte...
