The latest (tenth) edition of my Software Engineering textbook was published in April 2015. I have extensively revised and updated the 9th edition to reflect some of the key challenges for software engineering. These are the need for more agile development, the need to manage system complexity and the need to build systems that are secure and resilient. The most important changes are:

  • A completely revised chapter on agile methods
  • Self-contained, extensively revised chapters on reliability, safety and security engineering
  • A new chapter on resilience engineering (including cybersecurity)
  • New chapters on systems engineering and systems of systems

My site was recently hacked and several pages were corrupted. I have completely reinstalled the site but, in the process, several links were broken. To the best of my knowledge, the site is now clean and there should be no problems navigating the site.

As well as this new material, all other chapters have been revised and updated.
