That brings us to the last point about checklists - they DO NOT replace knowledge. An investor interviewed for the book said it best when describing that the checklist is “not a fail safe thing…you still need expertise and insight into the process to be able to ultimately perform each step correctly”. These checklists wouldn’t help me if I didn’t know what I was doing to begin with. Rather than being a “Step by Step to Collecting Data”, people can perform a task however they want and the checklist makes sure that in the end that task was performed correctly.

Checklists seem simple, Gawande says, and are sometimes hard for us to accept as a necessity when we're in high-powered jobs that rely on our skills and knowledge. But humbling ourselves by using a checklist can improve our performance and help us achieve more consistent results. "They remind us of the minimum necessary steps and make them explicit," writes Gawande. "They not only offer the possibility of verification but also instill a kind of discipline of higher performance."

An example from my own work is the process of creating a new blog post. Although I usually remember the steps of creating the content because it's part of my writing process—writing an outline, doing the research, drafting, and editing—there are plenty of other steps that I can easily forget. Adding images, working through multiple headline options to find the best one, and making sure image credits are correct are all standard tasks that are easy to overlook.
NO, I don’t. I call them “to do” lists. LOL! They’re very helpful, they keep me sane and keep stress away. For many years now, I keep a daily list prepped the night before; and a weekly list that’s prepped every Sunday. Keeps things smooth-sailing all the time. So at the end of the day, if all items are crashed-out (as in “done”!), I feel so good about myself. :)
