> manual checklists [can be] unnecessarily inefficent and/or unreliable

Shoutout to Dr. Atul Gawande's excellent book The Checklist Manifesto, an expansion of his New Yorker article [0]. One of his main points is that even the most competent people forget stupid stuff. He illustrates with examples from surgery, from aviation, from the construction industry, and others. He quotes a saying that aviation checklists are "written in blood."
