The A3 report is a two-page document that provides a structured way to identify and solve problems, propose and implement improvement initiatives, document and review progress of the changes.

The term A3 refers to a size of paper defined by ISO 216.

Templates are a great way to save time and improve report consistency. If you are new to A3 thinking, standard templates will help you learn the underlying process. If you are an A3 practitioner, they will provide you with the basis for evaluating A3 reports in your organization.

Do not focus on adherence of your reports to the standards. We do not know the best way of writing A3 reports. Treat the templates as rough guidelines, focus on your story line, and adapt the templates to your specific situation.

The following books have been the most influential on our understanding of the A3 process:

1. Managing to Learn by John Shook.
2. Understanding A3 Thinking by Durward K. Sobek II and Art Smalley.
