What is an A3 Report?
An A3 Report is a tool used for solving problems in your business processes.
As the name suggests it is a single-page report that summarises a full problem analysis. This leads to uncovering non-value adding activities for elimination. Established by Toyota these reports have become more and more complex over time using accompanying graphics to support the user.
Today they are a standard method for summarising problem-solving exercises, status reports, and planning exercises like value-stream mapping.
How to use?
An A3 report is a way of structuring and sharing knowledge. By enabling teams and their members to practice scientific thinking as a way of discovering and learning together. The tool promises immediate benefits by helping people structure and designs more effective approaches to problems (framing them insolvable ways, taking a data-based approach, using root-cause-analysis to find the point of origin for problems (gaps), encouraging careful problem analysis over quick abstract “solutions,” and so forth).
The strength of this report is that it gives an overview of your organisation’s problems all in one place. This helps users think through their entire process in great depth. Rather than attempting to find the best solution as soon as possible A3 thinking requires careful framing of a problem and patient analysis. This helps users consider how best to structure their solution and how to go about meaningful dialogue with people who actually touch the issue.

How to fill out an A3 report
8-steps to complete an A3 report
Generally, A3 report templates follow these 8 steps to solve problems:
- Problem description, Initial Perception (PLAN)
- Breakdown of the Problem, Problem Clarification (PLAN)
- Mapping out this step can be driven by a set of questions. For example, the “5 W’s (what, where, when, why, who) and 2H’s” (how, how many).
- Point of Cause, Setting Target (PLAN)
- Containment (PLAN)
- Cause and Effect, Ishikawa (PLAN)
- Follow Up Action, Corrective Actions (DO)
- Effect Confirmation (CHECK)
- Share the successfully implemented actions (ACT)
