Somewhat counterintuitively these high-reliability companies have MORE incidents than less reliable organizations that haven't removed the stigma around incident reporting because their goal is to learn from them and catch them early vs. punishing the unlucky individual who happened to step on whatever systemic land-mine exploded that day.
Looks like one of Dekker's books is already listed in this post, but another one worth checking out is his "Field Guide to Understanding Human Error"[1] which is a very approachable book focused on the aviation industry and the learnings (especially post WWII) that have made that industry so safe.
If you're working on this at your own company (especially if you're in a supervisor / executive position) it's incredibly powerful and impactful to be the incident champion who works to make incident response open and accessible across the org. So much catastrophic failure comes as a result of hiding the early signs due to fear retaliation or embarrassment.
Also worth checking out: we[2] hosted a mini conference on Incident Response earlier this year with lots of great videos from folks who have worked in this space for decades about everything from culture to practices: https://www.irconf.io/
