One benefit of 5 Whys is that it only costs your team a small amount of time to use, a team familiar with a process can conduct a complete 5 Whys session in less than an hour if the facilitator keeps things on task.
Because of its simplicity, the 5 Whys tool can be used for almost any problem. Use it to address a problem team members bring up, to address a problem a supervisor noticed, or to address the vague feeling that there is a problem when no one has been able to define what is actually wrong.
At the very least, a 5 Whys session facilitates communication and thought.
In a Six Sigma project environment, 5 Whys is usually deployed when processes involve human interactions or people-powered inputs, though it can be an effective start to brainstorming on any process.
