An “A3” is an international size piece of paper, approximately 11-by-17 inches. Using an A3 is an effective way to present a situation – a story that anyone can understand – all on one page.

It is a visual tool for problem-solving because it presents all of the main elements in a condensed space, allowing for on-the-spot review. It is a powerful management process encouraging learning through a scientific approach to problem solving. It includes a description of the current conditions, goals, analysis, and an action plan for implementing solutions.

There is no standard format for an A3. Each A3 suits the situation. At the end of this blog, a detailed example is provided that you can use and modify to suit your organization's situation.
