This edition of Business Analysis Techniques includes chapter contributions by Jonathan Hunsley, Adrian Reed and David Beckham. It has been a privilege to collaborate with them and to gain from their extensive knowledge and experience.

We also wish to thank our colleagues at AssistKD for their support during the writing and production process. In particular, we wish to thank Peter Thompson for his technical knowledge and expertise regarding UML techniques, Neil Shorter for his ever-present technical and security support, and Alan Paul for providing the extensive proof-reading service that has been so valuable on so many occasions.

Finally, this book could not have been produced without the professional publishing capability provided by Ian Borthwick and Becky Youé from BCS. It has been a pleasure working with them when developing this edition and, undoubtedly, the book has benefited from their expert support.
