I'm getting so very tired of safety/accident researchers claiming that root cause analysis is an invalid, blame-focused practice that ignores systems and complexity. Most root cause investigators that I know are pretty well oriented towards process, organization, and system issues as the fundamental sources underlying problems and accidents... and even some of our simplest analysis tools (e.g., TWIN) include specific checks for complex-system characteristics/behaviours (e.g., hidden system responses, separation between cause and effect).
I used to read a lot more than I do now... sometimes for pure enjoyment, but also for research about my favourite topics (like Root Cause Analysis, of course). Here are some of the books and reports on my root cause bookshelf right now, things I plan to read during the 4th quarter of 2014. I guess I'm in the mood for accident theory and models, and for big books!
