Op de vraag "Wat is een A3?", gaf John Shook het volgende antwoord:
The most basic definition of an A3 would be a P-D-C-A storyboard or report, reflecting Toyota’s way of capturing the PDCA process on one sheet of paper. But the broader notion of the A3 as a process – embodying the way of thinking represented in the format – captures the heart of lean management. In this context, an A3 document structures effective and efficient dialogue that fosters understanding followed by the opportunity for deep agreement. It’s a tool that engenders communication and dialogue in a manner that leads to good decisions, where the proposed countermeasures have a better chance of being effective because they are based on facts and data gathered at the place where the work is performed, from the people who perform it.
