This book is brief, pricise and packed with actionable advice. Atul Gawande treads on to science of complexity with a tool as simple as Check List. Highlighting the fraility of human memory and attention, he dives into experience and expertise from different industries to find a solution to problems which can be classified as simple, complex or coomplicated. He has taken great examples from Construction, Surgery and Aviation. The best thing in the book is contrast that Atul has drawn between simplicity of checklist as a concept, general reluctance to adapt that concept and the remarkable benefits of internalizing the use of checklists to solve complexity. It's one of those must read books which you can read every 6 months.
