To my family:
Lynda, Martin, Gareth and Karl
Thank you for your support and forbearance, and for understanding why I wanted to do this.

My thanks also to my friends and former colleagues at BAE Systems and the wider Estimating Community for allowing me the opportunity to learn, develop and practice my profession … and for suffering my brand of humour over the years. In particular, a special thanks to Tracey C, Mike C, Mick P and Andy L for your support, encouragement and wise counsel. (You know who you are!)
