How are 5 Whys used in safe?
Once a cause is identified, its root cause is explored with the 5 Whys technique. By simply asking ‘why’ multiple times, the cause of the previous cause is uncovered, and added to the diagram. The process stops once a suitable root cause has been identified and the same process is then applied to the next cause.
What is 5 why analysis PPT?
