How to Use the 5 Why’s for Problem Solving?

Imagine you’re a curious kid again, constantly asking “Why?” That’s the essence of the 5 Whys technique. It’s a simple, yet powerful problem-solving method that involves asking “Why?” five times to get to the root cause of an issue. Each answer forms the basis for the next question, peeling back layers of symptoms to reveal the core problem.

For example:

  1. Why did our website traffic drop? Because our bounce rate increased.
  2. Why did the bounce rate increase? Because the page load time slowed down.
  3. Why did the page load time slow down? Because we added new, unoptimized images.
  4. Why were unoptimized images added? Because the content team wasn’t trained on image optimization.
  5. Why wasn’t the content team trained? Because we didn’t have a clear onboarding process for new team members.

By the fifth “Why,” we’ve uncovered a fundamental issue that might have been overlooked with a surface-level analysis.

The Origins of 5 Whys: A Journey Through Time

The 5 Whys technique isn’t just some newfangled business fad. It’s got history, baby! Born in the 1930s, this method was the brainchild of Sakichi Toyoda, the founder of Toyota Industries. Toyoda wasn’t just building cars; he was revolutionizing problem-solving.

Toyota’s production system became legendary for its efficiency, and the 5 Whys played a starring role. By the 1970s, this technique had spread beyond the factory floors of Japan and into boardrooms around the world.

Fun fact: Toyoda’s method was so effective that NASA adopted it for their Apollo program. Talk about shooting for the stars!
