Do you need to find the cause for a work or personal problem?
This is a method to help determine the root cause of a problem by repeating the question "Why?"

Trust yourself. If you are working with other people, trust each other.

Examples
This diagram shows cause and effect.
Sometimes there is more than one cause.
Ask Why? until the root cause is determined. At the end, you can reverse the order of your reasons, making “therefore” statements.

Sometimes you only need to ask 3 WHYs to identify a root cause; sometimes you need to ask more in your analysis.

Take Action
The more you practice the 5 WHYs technique, the easier it will become. Just remember: don't ask Why too many times or you might lose focus.
By asking 5 WHYs, you may discover that your solution is not addressing the real issue you need to fix.
The next time you have trouble solving a problem, don't jump to conclusions - use the 5 WHYs!
