Based on Five Whys and Five Hows by Ron Bialek, Grace L. Duffy, and John W. Moran.

Summary

  • The Five Whys and Five Hows technique was created by Sakichi Toyoda.
  • It involves asking and answering the question "why?" in order to drill-down to the root of a problem.
  • Similarly, by asking "how?" about a problem or desired result, we can brainstorm solutions.
  • These are useful techniques to practice in teams seeking to solve problems by addressing root issues and understanding the cause and effects of existing problems.
