A-3 is a step-by-step template for applying plan-do-check-act, also known as PDCA or the Deming cycle. The name comes from the standard international paper size A-3, which is roughly 11” x 17”—this provides just enough space to condense information onto a single page.

This article includes a version of the template, explains how to use an A3 template, and highlights concepts of waste. This template was provided by Federal Home Loan Bank (FHLBank) of San Francisco.
