This edition introduces new material on recent incidents, and includes a new section that shows how many accidents occur through simple miscommunications within the organization, and how straightforward changes in design can often remove or reduce opportunities for human errors. The author's approach to learning as deeply as possible from previous experiences is made more valuable in this new edition, which for the first time brings together the approaches and cases of "What Went Wrong" with the managerially focussed material previously published in "Still Going Wrong".
