Five Whys¶
When exploring the options of a decision that needs to be made, five whys can help you to understand certain underlying reasons.
The number five is arbitrary, though usually enough. You can tell that you are at the end of a chain of whys when it's a core fundamental reason, and not predicated on assumption.
When revealing dilemmas you can find the end of a chain when you can answer the question 'why did this process fail?'
