Not much time for blogging today. But here are three excerpts from The Checklist Manifesto:

Every day there is more and more to manage and get right and learn. And defeat under conditions of complexity occurs far more often despite great effort rather than from a lack of it.
 It is not clear how we could produce substantially more expertise than we already have. Yet our failures remain frequent. They persist despite remarkable individual ability.
(our) know-how is often unmanageable. Avoidable failures are common and persistent, not to mention demoralizing and frustrating, across many fields – from medicine to finance, business to government. And the reason is increasingly evident: the volume and complexity of what we know has exceeded our individual ability to deliver its benefits correctly, safely, or reliably.
