Problem-solving lessons

ONE of the problem-solving lessons I learned from Toyota was called the 'A3 thinking.'

Developed in the 1940s, it was a concept based on the A3 sheet of paper, which is 11 by 17 inches in size, at the time, the biggest size of paper used in a photocopying machine. The idea was that the A3 paper could contain all the details everyone needs to solve a problem.
