Problems can occur at any given moment, and when they do, your team needs to act quickly to minimize damage. But finding a quick solution might not be enough, figuring out why it occurred in the first place and getting down to the root of the problem will help mitigate any further problems down the road.
Implementing Taiichi Ohno’s 5 Why’s technique directly after a problem is resolved will help get to the core of the issue. Taiichi Ohono, pioneer of the Toyota Production System in the 1950s, believed that finding out why something malfunctioned or why a problem occurred is the only way to find a true solution.
In Ohno’s wise words, “The root cause of any problem is the key to a lasting solution.”
It is always a challenge to figure out why and how a problem occurred. Using the 5 Whys as a problem solving strategy will help to make this process more manageable. Simply ask your group the question “Why?” five times. That’s right, it is that easy!
