Engineering a Safer World

This website contains a link to my new book "Engineering a Safer World" plus some related papers
that might interest you. This website is under construction and will grow, including the addition of
more teaching materials for the book.

Engineering is experiencing a technological revolution, but the basic engineering techniques applied
in safety and reliability engineering, created for a simpler, analog world, have changed very little over
the years. In this book, I describe a new approach to safety and risk management--better suited to
today's complex, sociotechnical, software-intensive world. The approach is based on modern
systems thinking and systems theory.

The new approach has now been used extensively on real-world systems and it is proving to be
more effective, less expensive, and easier to use. The book describes a new model of causation
(STAMP or Systems-Theoretic Accident Model and Processes) that can be used to improve the design,
operation, and management of potentially dangerous systems or products.

There was a WORKSHOP ON ENGINEERING A SAFER WORLD at MIT on April 17-19, 2012.
The first day was a tutorial on STPA, the new hazard analysis method based on STAMP.
Materials from the workshop can be obtained by clicking here.

Because the book has now been published, as agreed in my contract with the publisher,
MIT Press, they are now controlling the distribution of the book. There is still a free on-line version
(readable but not printable) but it is located on the MIT Press website (look in the left column and
click on the link that says "Read the complete text of this book."
