PROBLEM SOLVING A3
The A3 problem-solving is a lean approach to reporting issues and presenting solutions. A simple method developed by Toyota, it involves documenting the problem along with its current outcome and proposed change on a single A3-sized paper (420 x 297 mm), hence the name. It can be used for preparing a process change proposal, reporting on project status, or solving a problem. The benefits of using the A3 problem-solving method are:
Faster problem-solving through logical reasoning and the use of a step-by-step visual process. The requirement to identify the root cause ensures that issues are addressed, not just temporarily covered up.
Easier problem-solving, thanks to the use of objective, critical thinking encouraged by the A3 structure.
Developing problem-solving skills in employees through the repeated use of a structured tool to identify root causes and their best solutions. Using the same tool across all levels of the company also encourages collaboration between departments and knowledge sharing.
A3 reports help maintain and preserve company knowledge, support the upkeep of good operational policies, and build a strong growth culture based on solving the company's real problems.
