The A3 report is a structured, one-page document that outlines the problem, proposed solution, and plan for implementation. It is a powerful tool for problem-solving, decision-making, and communication in manufacturing and service organizations worldwide.

The A3 report consists of several sections:

Problem statement
Current situation analysis
Root cause analysis
Proposed solution
Implementation plan
Monitoring and verification plan

Each section provides a clear and concise overview of the problem and the proposed solution.

Problem statement

This section clearly defines the problem and its impact on the organisation. The project owners need to be write it in measurable terms, such as a reduction in quality or an increase in costs, and should provide a clear understanding of the problem’s scope.

Current situation analysis

This section provides a detailed analysis of the current situation, including relevant data and information about the problem. It breaks down the problem into smaller, more manageable parts to ensure that all aspects of the problem are considered, and to identify potential causes.

Root cause analysis

This section identifies the underlying cause of the problem by using techniques such as the 5 Whys or Fishbone diagrams. It provides a clear understanding of the root cause of the problem and is critical in identifying the underlying cause, rather than just treating the symptoms.

Proposed solution

This section describes the actions that will be taken to address the problem. It is based on the findings of the root cause analysis and provides a detailed plan for implementation.

Implementation plan

This section provides a timeline for implementing the proposed solution and includes the responsibilities of each team member. It also includes a monitoring and verification plan to ensure that the solutions are effective.
