Acknowledgements

We would like to thank the case writers who have granted us per-
mission to use their work in this book and indeed the practitioners
who generously gave their time during the development of our
own case studies. We would also like to thank those of our col-
leagues and our students, past and present, who have contributed
to our thinking and in particular we are grateful for the patient
support provided by our secretaries, Tracy Brawn and Anna
Newman-Brown.
