This open access book constitutes the proceedings of the 19th International Conference on Agile Software Development, XP 2018, held in Porto, Portugal, in May 2018. XP is the premier agile software development conference combining research and practice, and XP 2018 provided a playful and informal environment to learn and trigger discussions around its main theme – make, inspect, adapt. The 21 papers presented in this volume were carefully reviewed and selected from 62 submissions. They were organized in topical sections named: agile requirements; agile testing; agile transformation; scaling agile; human-centric agile; and continuous experimentation.

The need to count on trusted systems is growing day by day. Together with traditional domains such as medical devices, automotive, railway, aeronautical, space and telecommunications, new applications and services are coming up everyday. Terms such as ubiquitous, pervasive, or autonomic computing, products under the general umbrella of smart devices or the use of large wireless sensors networks indicate a clear trend in the increase of application complexity and dependency. Our daily life dependability on computers and computer systems is growing at a high rate, and validation is gaining importance at the same rate. To perform a proper validation process encounters a number of problems both from a technical and from a managerial point of view, also considering that the complexity of the underlying software is growing as well. As a consequence inputs from research contributions and experience from industry are required in order to enable innovative, and often more rigorous, approaches. The System Testing and Validation Workshop is a series of events initiated in the year 2002 and seeks to provide answers to the many open issues related to validation.

Software and system assurance is a growing concern. A look at some of the domains involved, including at least medical devices, automotive, railway, aeronautical, space and telecommunications provides a feeling on the importance of the topic. For many of these domains, and partly because of the increasing complexity of software, validation is an open issue and not straightforward at all, both from a technical and from a managerial point of view. Another topic to consider is that validation is often performed at the end the development lifecycle, which results in obvious calendar problems. One of the consequences is that the relevance of lifecycle processes such as system testing and validation must be broadened. Therefore inputs from research and experience from industry is required in order to enable innovative, and often more rigorous, approaches.
