Checklist Manifesto

It is common to misconceive how checklists function in complex lines of work. They are not comprehensive how-to guides, whether for building a skyscraper or getting a plane out of trouble. They are quick and simple tools aimed to buttress the skills of expert professionals.

To be sure, checklists must not become ossified mandates that hinder rather than help. Even the simplest requires frequent revisitation and ongoing refinement.
