A3 problem solving is a problem-solving technique that uses a specific type of form called an A3 form. An A3 form looks like a big piece of paper with a bunch of boxes and lines on it. It's basically like a map that tells you how to solve a problem. When you have a problem you need to solve, you fill out the A3 form with information about the problem and then use that to figure out the best way to solve it. It's kind of like having an outline or plan before you start working on something. That way, you can make sure you are tackling the problem in the most effective way.
