A3 Thinking is a problem-solving approach Toyota developed using A3 reports. The name A3 here refers to the international paper size of 11.7 by 16.5 inches the reports are printed on. This concise format forces clarity and structured communication. Indeed, the A3 report is a structured problem-solving process that follows the Plan-Do-Check-Act (PDCA).
A3 thinking fosters critical and scientific thinking, digging deeper into root causes. But, A3 thinking is beyond cerebral activity. It transitions problem-solving to learning through concrete actions on the field. It strives for a deep understanding of issues to derive meaningful and sustainable solutions.
