The XP conference series established in 2000 was the first conference dedicated to agile processes in software engineering. The idea of the conference is to offer a unique setting for advancing the state of the art in the research and practice of agile processes. This year’s conference was the ninth consecutive edition of this international event. The conference has grown to be the largest conference on agile software development outside North America. The XP conference enjoys being one of those conferences that truly brings practitioners and academics together. About 70% of XP participants come from industry and the number of academics has grown steadily over the years. XP is more of an experience rather than a regular conference. It offers several different ways to interact and strives to create a truly collaborative environment where new ideas and exciting findings can be presented and shared. For example, this year’s open space session, which was “a conference within a conference”, was larger than ever before. Agile software development is a unique phenomenon from several perspectives.

This book constitutes the refereed proceedings of the 16th International Conference on Product-Focused Software Process Improvement, PROFES 2015, held in Bolzano, Italy, in December 2015. The 18 revised full papers presented together with 10 short papers and 18 workshop papers were carefully reviewed and selected from 50 submissions. The papers are organized in topical sections on lessons learned from industry-research collaborations; instruments to improve the software development process; requirements, features, and release management; practices of modern development processes; human factors in modern software development; effort and size estimation validated by professionals; empirical generalization; software reliability and testing in industry; workshop on processes, methods and tools for engineering embedded systems; workshop on human factors in software development processes; and workshop on software startups: state of the art and state of the practice.

The LESS 2010 conference marked the inaugural scientific gathering focused on advancing the “lean enterprise software and systems” knowledge base. It facilitated interactions between the lean product development and agile communities, alongside innovative concepts from the beyond budgeting school of thought. Organized in collaboration with the Lean Software and Systems Consortium (LSSC), the event established itself as a series aimed at enhancing research and practice by uniting leading researchers and practitioners. The conference attracted a diverse mix of participants, including academics, researchers, consultants, and industry professionals. Its goal was to leverage this varied community to further research and practical knowledge on lean thinking in software business and development. Over 60% of the speakers were from the industry, with the remainder from academia. As the conference evolves, it is set to become the premier event for lean thinking in systems and software development. Its growth and credibility will be supported by the communities and knowledge exchange it fosters. LESS provides multiple avenues for collaboration, aiming to introduce fresh ideas and promote a highly interactive environment during and after each conference iteration.

This conference proceedings covers various aspects of software process improvement, focusing on enforcement, alignment, and tailoring of processes. It discusses the introduction of the Rational Unified Process and offers an industrial example of maintaining a large process model aligned with a process standard. The content highlights synergies between common criteria and process improvement, with a particular emphasis on small and medium enterprises (SMEs). It explores methods for determining practice achievement in project management within SMEs and analyzes the perceived value of CMMI practices. The proceedings also delve into lightweight software process modeling for small companies and present empirical studies on software process improvement. Additionally, it includes a longitudinal case study on organizing improvement work and experiments with release planning methods for web application development. New avenues for SPI are investigated, including legal risk management strategies and innovative tools like iCharts for value management. The role of organizational learning through project postmortem reviews is examined, alongside methodologies for modeling software processes as adaptive work systems. The performance of software complexity metrics in open-source projects is compared, and critical success factors for SPI initiatives in the Brazilian software industry are identified. Finally, the impact of component-level tes

Unbelievable, we have reached the seventh edition of the XP2k+n conference! We started at the outset of the new millennium, and we are still proving that agile pr- esses were neither a millennium bug nor a YAF (yet another fad). In its first editions, this conference was a get-together of a few pioneers who - bated about how to make agile processes and methods accepted by the mainstream researchers and practitioners in software engineering. Now agile approach to software development has been fully accepted by the software engineering community and this event has become the major forum for understanding better the implications of agility in software development and proposing extensions to the mainstream approaches. These two aspects were fully reflected in this year’s conference. They were - flected in the keynote speeches, which covered the background work done starting as early as the early eighties by Barry Boehm, definition of the field by Kent Beck, a successful industrial application in a success story by Sean Hanly, the perspective and the future of agile methods in large corporations by Jack Järkvik, and even some - sightful views from a philosopher, Pekka Himanen.
