Writing a book about integrity engineering infers you can learn it from books. It’s sort of true, but there are plenty of books. And codes, recommended practices technical papers and all those other sources, thousands of them, you don’t have time to read.
Can we shrink them down to the most important ones? Pick out those with superlative general application, squeeze each page or two and then call them something snappy like … Rules of Thumb? It’s a massive call.
