Many thanks to all. I should have realised there would be a glossary.
And thank you for the pointer to Pupulidy. A quick look at his conclusions suggests that he has reached conclusions similar to those in "Rethinking Reputational Risk" and earlier research, particularly a report from the Cass Business School called "Roads to Ruin". Between them about 30 case studies of major corporate disasters and analysis of the multiple causes involved in most of the failures.
In a nutshell their conclusions can be reduced to two main points. First, most major failures have people-system failures at their roots, which means that to fix the problem you have to fix the people-system weaknesses, which may be multiple and complex in nature and origin.
Second, people systems are driven by successive layers of leaders, which means that to fix it you may have to 'fix' leaders, often top leaders, too. This presents practical problems outside aviation safety which, from the outside, looks like a particularly enlightened community.
