More general material on software and systems engineering teaching and research is available from my professional web site and blog. The book has been designed to be closely integrated with the web and, as well as the web sections referenced in the text, I have also made some chapters 'web-only'. This website provides a range of supplementary material to support the use of the 9th edition of my textbook on software engineering. See the preface for details of the changes and the contents list for information about the book's structure. This is a major revision of the previous edition with extensive reorganization and 30-40% new material.

My personal web site has more information. As well as writing, I now do a range of software-related things, paid and unpaid, that I find interesting. I retired as a full professor of software engineering at St Andrews University, Scotland in 2014. social and organizational factors affect complex systems and systems engineering processes. Since the early 1990s, I have taken a sociotechnical and not simply a technical view of software engineering where I looked at how human. I have worked in several areas of software engineering – software tools and environments, requirements engineering, dependable systems and large-scale complex systems. I started using the Internet in the early 1980s and my first web site was published in 1995.

So I have lived through changes to computer generations from mainframes to minicomputers to PCs and mobile devices. I wrote my first computer program in 1970 and have been involved in software engineering research and teaching since the late-1970s. The website for the 9th edition is still available but is not maintained. This is the website for the 10th edition, which includes additional learning materials – case studies, presentations and videos – for students and educators. My book is widely used across the world as a student text, has been translated into many languages and, in different editions and languages, has sold almost a million copies. The 10th edition was published in 2015 with new material on resilience engineering, systems engineering and systems of systems many chapters have been extensively revised including ‘Agile Software Engineering’, ‘Reliability, ‘Safety’ and ‘Security’. The 1st edition of Software Engineering was published in 1982 and it has been regularly revised and updated since then.
