This textbook, which has become the leading source for empirical software engineering research through its earlier editions, provides an in-depth introduction to experimentation in software engineering. The focus is on the steps to go through when conducting experiments. It also introduces a structure for selecting a research design and an introduction to systematic literature reviews, surveys, and case study research. Experiments are valuable tools for all software engineers who evaluate and choose between different solutions, methods, techniques, languages, and tools.The book has three main parts. Part I introduces empirical research through a structure for selecting a research design and explains several essential areas related to empirical research. Moreover, it provides introductions to systematic literature reviews, experiments, surveys, and case studies. Part II devotes one chapter to each of the five experiment steps: scoping, planning, execution, analysis, and result presentation. Part III completes the presentation with two examples. Assignments and statistical material are provided in appendices. The book provides indispensable information regarding empirical studies, particularly for experiments, but also for systematic literature studies, surveys, and case studies. This new edition comprises substantial new material. This includes a chapter on selecting a research design, which helps put experimentation into a broader context of other research approaches. Furthermore, a new chapter on survey research has been added. Novel contributions concerning A/B testing, replications, open science, validity threats, paired comparison design and tools for statistical analysis have been added. Moreover, systematic literature studies, experiments, and case study research descriptions have been consolidated. The book has also been updated based on the evolution of software engineering since the previous edition's publication.The book is intended for students, teachers, researchers, and practitioners who would like to compare different options, for example, feature designs, or different development methods, techniques, languages, or tools.  Teachers can use the book for undergraduate or graduate students; the book can be used as a course book on experimentation and empirical studies in general. Researchers will also benefit from the book by learning more about how to conduct empirical studies. Likewise, practitioners may use it as a “cookbook” when evaluating different solutions, alternatively for evaluating new methods or techniques before implementing them in their organisation.

It is my belief that software engineers not only need to know software engineering methods and processes, but that they also should know how to assess them. Conse­ quently, I have taught principles of experimentation and empirical studies as part of the software engineering curriculum. Until now, this meant selecting a text from another discipline, usually psychology, and augmenting it with journal or confer­ ence papers that provide students with software engineering examples of experi­ ments and empirical studies. This book fills an important gap in the software engineering literature: it pro­ vides a concise, comprehensive look at an important aspect of software engineer­ ing: experimental analysis of how well software engineering methods, methodologies, and processes work. Since all of these change so rapidly in our field, it is important to know how to evaluate new ones. This book teaches how to go about doing this and thus is valuable not only for the software engineering stu­ dent, but also for the practicing software engineering professional who will be able to • Evaluate software engineering techniques. • Determine the value (or lack thereof) of claims made about a software engineer­ ing method or process in published studies. Finally, this book serves as a valuable resource for the software engineering researcher.
