It is fantastic to see this pan out in real life. I read the checklist manifesto by Atul Gawande who helped to author the WHO checklist. It really one of these mind expanding books that everyone should read. I have seen below comments that ask why checklists are not standard even though they were pivotal in reducing flight accidents. The reason is that knowledge is often siloed, and people tend to overestimate themselves. How many checklists are you using at work? If none, ask yourself why, and if they could be helpful.

The book also talks about the design of checklists which is not trivial at all.
