This book constitutes the refereed proceedings of the 20th International Conference on Product-Focused Software Process Improvement, PROFES 2019, held in Barcelona, Spain, in November 2019. The 24 revised full papers 4 industry papers, and 11 short papers presented were carefully reviewed and selected from 104 submissions. The papers cover a broad range of topics related to professional software development and process improvement driven by product and service quality needs. They are organized in topical sections on testing, software development, technical debt, estimations, continuous delivery, agile, project management, microservices, and continuous experimentation. This book also includes papers from the co-located events: 10 project papers, 8 workshop papers, and 4 tutorial summaries.

On behalf of the PROFES Organizing Committee we are proud to present to you the proceedings of the 6th International Conference on Product Focused Software Process Improvement (PROFES 2005), held in Oulu, Finland. Since 1999, PROFES has established itself as one of the recognized inter- tional software process improvement conferences. Thepurposeoftheconferenceistobringtolightthemostrecent?ndingsand results in the area and to stimulate discussion between researchers, experienced professionals,andtechnologyproviders.Thelargenumberofparticipantscoming from industry con?rms that the conference provides a variety of up-to-date t- ics and tackles industry problems. The main theme of PROFES is professional software process improvement (SPI) motivated by product and service quality needs. SPI is facilitated by software process assessment, software measurement, process modeling, and technology transfer. It has become a practical tool for quality software engineering and management. The conference addresses both the solutions found in practice and the relevant research results from academia. This is re?ected in the 42 full papers, which are – as in the years before – a well-balanced mix of academic papers as well as industrial experience reports.

On behalf of the PROFES Organizing Committee we are proud to present the proce- th ings of the 11 International Conference on Product-Focused Software Process Improvement (PROFES 2010), held in Limerick, Ireland. Since the first conference in 1999 the conference has established its place in the software engineering community as a respected conference that brings together participants from academia and industry. The roots of PROFES are in professional software process improvement motivated by product and service quality needs. The conference addresses both the solutions found in practice as well as relevant research results from academia. To ensure that PROFES retains its high quality and focus on the most relevant research issues, the conference has actively maintained close collaboration with industry and subsequently widened its scope to the research areas of collaborative and agile software devel- ment. The main themes of this year’s conference were “Agile and Lean Processes” and “Engineering Service-Oriented Systems. ” These two main themes enabled us to cover the contemporary software devel- ment demands and trends in a comprehensive manner and to tackle the most important current challenges identified by the software industry and software research com- nity––namely, the shift of focus from "products" to "services. ” The technical program featured invited talks, research papers, and experience reports on the most relevant topics related to processes for developing software-intensive services and products. In addition, a number of workshops and tutorials were hosted.

This book constitutes the refereed proceedings of the 12 International Conference on Product-Focused Software Process Improvement, PROFES 2011, held in Torre Canne, Italy, in June 2011. The 24 revised full papers presented together with the abstracts of 2 keynote addresses were carefully reviewed and selected from 54 submissions. The papers are organized in topical sections on agile and lean practices, cross-model quality improvement, global and competitive software development, managing diversity, product and process measurements, product-focused software process improvement, requirement process improvement, and software process improvement.

This book constitutes the refereed proceedings of the 22nd International Conference on Product-Focused Software Process Improvement, PROFES 2021, held in Turin, Italy, in November 2021. Due to COVID-19 pandemic the conference was held as a hybrid event. The 20 revised papers, including 14 full papers, 3 short papers and 3 industry papers, presented were carefully reviewed and selected from 48 submissions. The papers cover a broad range of topics related to professional software development and process improvement driven by product and service quality needs. They are organized in the following topical sections: agile and migration, requirements, human factors, and software quality.

A vital new publication for scientists and researchers in the field, this book constitutes the refereed proceedings of the 8th International Conference on Product Focused Software Process Improvement, PROFES 2007, held in Riga, Latvia in July 2007. The 29 revised full papers, along with four reports on workshops and tutorials and four keynote addresses were carefully reviewed and selected from 55 submissions. The papers constitute a balanced mix of academic and industrial aspects; they are organized in topical sections for ease of reference.

This book constitutes the refereed proceedings of the 19th International Conference on Product-Focused Software Process Improvement, PROFES 2018, held in Wolfsburg, Germany, in November 2018. The 16 revised full papers and 8 short papers presented together with 10 workshop papers and 2 industry talks were carefully reviewed and selected from 65 submissions. The papers are organized in the following topical sections: processes and methods; empirical studies in industry; testing; measuremene and monitoring; and global software engineering and scaling. Further relevant topics were added by the events co-located with PROFES 2018, the Second International Workshop on Managing Quality in Agile and Rapid Software Development Processes (QUASD) and the Third Workshop on Hybrid Software and System Development Approaches (HELENA).
