The A3 Project Report tool is ideal for systematically structuring and standardizing your problem-solving process. This free template aims to assist you in tackling workplace problems.
The A3 template is based on the A3 problem-solving method, which is a popular method for continuous improvement in Lean and Six Sigma methodologies. It walks you through a structured process of defining, analyzing, and resolving a problem, allowing you to communicate your findings and proposed solutions clearly.
The Template also includes an example of a complete A3 to use as benchmarking and as an example of how a complete A3 can look.
Learn how to conduct A3 problem solving with our in-depth A3 Problem Solving Guide.
An A3 Problem Solving Template is a structured approach to identifying and resolving issues using a single sheet of paper—often sized A3 (11” x 17”). Derived from Lean management practices, this concise format encourages teams to think systematically, focus on root causes, and develop effective countermeasures.
On this page, you can download our A3 Problem Solving Template, which will guide you through:
- Clarifying the Problem Statement: Clearly define the issue at hand by outlining its background, scope, and impact on your processes or goals.
- Identifying Root Causes: Use tools like the “5 Whys” or Fishbone Diagrams to delve beneath surface-level symptoms and reveal fundamental issues.
- Developing Countermeasures: Propose targeted actions that will address the identified root causes and prevent recurrence.
- Implementing and Checking Results: Assign responsibilities, set timelines, and monitor how effectively each action is resolving the problem.
- Reflecting and Sharing Lessons Learned: Document and communicate insights gleaned from the process so that everyone can benefit from the improvement.
