Remember when asking your parents why over and over was a bad thing? Well, later in life, it turns out that's not so bad. Enter the 5 Whys, an important method that uses root cause analysis to determine what is causing production issues.

"The 5 Whys are an important part of lean problem solving and quality management. In practice, the first 1-3 Whys you ask about the cause of an issue don't answer the root cause of the problem. To get to the bottom of it all, you have to ask 5 Whys. You'll get to what's truly behind the root cause of the issue as you get to the fourth and fifth Whys. Later when a countermeasure is realized, you follow it through to prevent the problem from happening again."
