I was lucky to win an auction a few months ago of the book "Honda: the man and his machines" autographed by Mr. Honda. The book, even without his autograph, is worth buying.
Right now I am about to finish "Whatever happened to the british motorcycle industry", by Bert Hopwood -senior designer in Triumph, Norton and BSA-. Once you read both books you understand how the attitude of the manager affects the product and the productivity, and understand why Honda survived and the rest sinked -included the poor spanish industry-.
