This book is dedicated to Joan Pallix, a pioneer in our field. Joan’s ingenuity brought many
of us together to develop early demonstrations of system health management technologies for
the Space Shuttle Thermal Protection System, and her trailblazing approach provided a key
foundation of the System Health Management process that we describe herein. Her dedica-
tion, originality,and technical expertise earned the respect of the System Health Management
community.
