In The Checklist Manifesto – How to Get Things Right (2009), Atul Gawande – surgeon, Harvard professor, and New Yorker staff writer – recommends the strategic use of checklists to manage complexity. Gawande notes that while most domains of human activity in the modern era have witnessed a striking expansion in knowledge, it has become more and more difficult to apply this knowledge effectively. Through carefully chosen case studies and anecdotes, and a bevy of facts and statistics, Gawande persuasively demonstrates how an ostensibly simple tool like the checklist has substantially reduced avoidable errors and increased successful outcomes across any number of critical industries, including surgery, construction, aviation, disaster management, and investment management.
Today, highly complex projects straddle multiple specialized disciplines and involve many different individuals and teams. We inevitably miss key steps in addressing difficult challenges, due to limited memory, faltering attention, poor communication, unforseen events, or other factors. In effect, while we know a lot more today, we often don't apply our knowledge effectively. Therefore, we are constantly faced with avoidable errors in fields such as surgery, disaster management, software design, intelligence failures, and finance – indeed, in any area of human endeavor that requires the quick application of enormous knowledge to challenging problems with uncertain outcomes.
