Does Asking Why Make You Smarter?

Perhaps not but asking why five times in a row is a simple and proven technique for getting to the root cause of a problem or issue.  And getting to the root cause  greatly improves your odds of  finding good solutions.

The technique known as the five-whys was originally developed by Sakichi Toyoda, often called the father of the industrial revolution in Japan.   Let’s assume for example that a customer order is not shipped from the dock on time. Here is how the technique works:

• Why1: Why did the shipment not leave the dock on time?
  • The order was not completed before the last truck left
• Why2: What the order not complete?
  • The automated assembler on line 3 broke down
• Why3: Why did the automated assembler break down?
  • We failed to complete the maintenance schedule and the the control froze
• Why4: Why did we fail to complete maintenance?
  • Frank, a new employee forgot to do it
• Why5: Why did Frank forget to do it?
  • It was not included in his new employee training

Although a bit simplistic it shows the power of the five-whys technique for driving thinking to the root cause. A problem with a customer order was ultimately caused by a fault in new employee training. Learning such simple techniques is a powerful way to improve cognition and so they will be a frequent topic on the Next Brain Blog.

For a more detailed overview, including some of the short comings of the technique check out How to use the Five WHY approach.
