I've thought this way about other books, and seen this thought expressed about The Checklist Manifesto ("it should have been a 20 page pamphlet"). But I feel that most of the length (say, at least 75% of the book's published length) is necessary and justified.
Not because the concept itself requires so many pages to understand, but because it takes several repeated high-profile examples of checklists making a big difference, before the feeling of "it's just a checklist, what's the big deal" - that a lot of people express upon hearing the idea first - is replaced with understanding and internalization.
