The writing of this book was partially funded by a Maryland Open Source Textbook Initiative (M.O.S.T) grant.

Thanks to Ken Ellson (obm) and Betty Niimi, who taught me half of what I know about project management and requirements engineering.  The rest I learned from really bad managers who let projects get completely out of hand, and thereby funded most of my consulting career.

Thanks to all of the requirements analysts that I have worked with over the decades.  I learned about requirements engineering from the good and bad requirements analysts.
