Extreme Programming And Agile Methods

This open access book constitutes the proceedings of the 21st International Conference on Agile Software Development, XP 2020, which was planned to be held during June 8-12, 2020, at the IT University of Copenhagen, Denmark. However, due to the COVID-19 pandemic the conference was postponed until an undetermined date. XP is the premier agile software development conference combining research and practice. It is a hybrid forum where agile researchers, academics, practitioners, thought leaders, coaches, and trainers get together to present and discuss their most recent innovations, research results, experiences, concerns, challenges, and trends. Following this history, for both researchers and seasoned practitioners XP 2020 provided an informal environment to network, share, and discover trends in Agile for the next 20 years. The 14 full and 2 short papers presented in this volume were carefully reviewed and selected from 37 submissions. They were organized in topical sections named: agile adoption; agile practices; large-scale agile; the business of agile; and agile and testing.

The first book to cover Agile Modeling, a new modeling technique created specifically for XP projects eXtreme Programming (XP) has created a buzz in the software development community-much like Design Patterns did several years ago. Although XP presents a methodology for faster software development, many developers find that XP does not allow for modeling time, which is critical to ensure that a project meets its proposed requirements. They have also found that standard modeling techniques that use the Unified Modeling Language (UML) often do not work with this methodology. In this innovative book, Software Development columnist Scott Ambler presents Agile Modeling (AM)-a technique that he created for modeling XP projects using pieces of the UML and Rational's Unified Process (RUP). Ambler clearly explains AM, and shows readers how to incorporate AM, UML, and RUP into their development projects with the help of numerous case studies integrated throughout the book. AM was created by the author for modeling XP projects-an element lacking in the original XP design The XP community and its creator have embraced AM, which should give this book strong market acceptance Companion Web site at www.agilemodeling.com features updates, links to XP and AM resources, and ongoing case studies about agile modeling.

This open access book constitutes the proceedings of the 22nd International Conference on Agile Software Development, XP 2021, which was held virtually during June 14-18, 2021. XP is the premier agile software development conference combining research and practice. It is a unique forum where agile researchers, practitioners, thought leaders, coaches, and trainers get together to present and discuss their most recent innovations, research results, experiences, concerns, challenges, and trends. XP conferences provide an informal environment to learn and trigger discussions and welcome both people new to agile and seasoned agile practitioners. This year’s conference was held with the theme “Agile Turns Twenty While the World Goes Online”. The 11 full and 2 short papers presented in this volume were carefully reviewed and selected from 38 submissions. They were organized in topical sections named: agile practices; process assessment; large-scale agile; and short contributions.

Accountability. Transparency. Responsibility. These are not words that are often applied to software development. In this completely revised introduction to Extreme Programming (XP), Kent Beck describes how to improve your software development by integrating these highly desirable concepts into your daily development process. The first edition of Extreme Programming Explained is a classic. It won awards for its then-radical ideas for improving small-team development, such as having developers write automated tests for their own code and having the whole team plan weekly. Much has changed in five years. This completely rewritten second edition expands the scope of XP to teams of any size by suggesting a program of continuous improvement based on: Five core values consistent with excellence in software development Eleven principles for putting those values into action Thirteen primary and eleven corollary practices to help you push development past its current business and technical limitations Whether you have a small team that is already closely aligned with your customers or a large team in a gigantic or multinational organization, you will find in these pages a wealth of ideas to challenge, inspire, and encourage you and your team members to substantially improve your software development. You will discover how to: Involve the whole team–XP style Increase technical collaboration through pair programming and continuous integration Reduce defects through developer testing Align business and technical decisions through weekly and quarterly planning Improve teamwork by setting up an informative, shared workspace You will also find many other concrete ideas for improvement, all based on a philosophy that emphasizes simultaneously increasing the humanity and effectiveness of software development. Every team can improve. Every team can begin improving today. Improvement is possible–beyond what we can currently imagine. Extreme Programming Explained, Second Edition, offers ideas to fuel your improvement for years to come.

It was 1999 when Extreme Programming Explained was ?rst published, making this year’s event arguably the ?fth anniversary of the birth of the XP/Agile movement in software development. Our fourth conference re?ected the evolution and the learning that have occurred in these exciting ?ve years as agile practices have become part of the mainstream in software development. These pages are the proceedingsof XP Agile Universe 2004, held in beautiful Calgary, gateway to the Canadian Rockies, in Alberta, Canada. Evidentintheconferenceis thefactthatourlearningis still inits earlystages. While at times overlooked,adaptation has beena core principleof agile software development since the earliest literature on the subject. The conference and these proceedings re- force that principle. Although some organizations are able to practice agile methods in the near-pure form, most are not, re?ecting just how radically innovativethese methods areto thisday. Anyinnovationmustcoexistwithan existingenvironmentandagileso- ware development is no different. There are numerous challenges confronting IT and software development organizations today, with many solutions pitched by a cadre of advocates. Be it CMM, offshoring, outsourcing, security, or one of many other current topics in the industry, teams using or transitioning to Extreme Programming and other agile practices must integrate with the rest of the organization in order to succeed. The papers here offer some of the latest experiences that teams are having in those efforts. XP Agile Universe 2004consisted of workshops,tutorials, papers, panels, the Open Space session, the Educators’ Symposium, keynotes, educational games and industry presentations.

This book contains most of the papers presented at the 4th International C- ference on Extreme Programming and Agile Processes in Software Engineering (XP 2003), held in Genoa, Italy, May 2003. The XP 200n series of conferences were started in 2000 to promote the - change of new ideas, research and applications in the emerging ?eld of agile methodologies for software development. Over the years, the conference has - come the main world forum for all major advances in this important ?eld. Also this year the contributions to Agile Methodologies and Extreme P- gramming were substantial. They demonstrate that the topic is continuing to gain more and more momentum. In spite of some criticism of agile meth- ologies, everyone agrees that they address some unresolved needs of software practitioners. People still do not know how to develop software on time, with the desired features, and within the given budget! This volume is divided into several thematic sections, easing reader’s na- gation through the content. Full papers are presented ?rst, followed by research reports, papers from the Educational Symposium, and papers from the Ph.D. Symposium. The presentations given during three panel sessions held at the conference conclude the book. The section on Managing Agile Processes includes contributions highlighting the sometimes di?cult relationship between agile methodologies and mana- ment, and includes approaches and suggestions that should facilitate the acc- tance of agile methodologies at the di?erent levels of management.

This book contains the refereed proceedings of the 15th International Conference on Agile Software Development, XP 2014, held in Rome, Italy, in May 2014. Because of the wide application of agile approaches in industry, the need for collaboration between academics and practitioners has increased in order to develop the body of knowledge available to support managers, system engineers, and software engineers in their managerial/economic and architectural/project/technical decisions. Year after year, the XP conference has facilitated such improvements and provided evidence on the advantages of agile methodologies by examining the latest theories, practical applications, and implications of agile and lean methods. The 15 full papers, seven short papers, and four experience reports accepted for XP 2014 were selected from 59 submissions and are organized in sections on: agile development, agile challenges and contracting, lessons learned and agile maturity, how to evolve software engineering teaching, methods and metrics, and lean development.

Software development is being revolutionized. The heavy-weight processes of the 1980s and 1990s are being replaced by light-weight, so called agile processes. Agile processes move the focus of software development back to what really matters: running software. This is only made possible by accepting that software developmentisacreativejobdoneby,with,andforindividualhumanbeings.For this reason, agile software development encourages interaction, communication, and fun. This was the focus of the Fifth International Conference on Extreme P- grammingandAgileProcessesinSoftwareEngineeringwhichtookplacebetween June 6 and June 10, 2004 at the conference center in Garmisch-Partenkirchen at the foot of the Bavarian Alps near Munich, Germany. In this way the conference provided a unique forum for industry and academic professionals to discuss their needs and ideas for incorporating Extreme Programming and Agile Metho- logies into their professional life under consideration of the human factor. We celebrated this year’s conference by re?ecting on what we had achieved in the last half decade and we also focused on the challenges we will face in the near future.
