5WH is a problem-solving technique that is simple to ask but not always easy to complete. Aristotle is credited with being the source.
5WH consists of the 5 W's and 1 H.
5 W's:
(1) who
(2) what
(3) when
(4) where
(5) why
1 H:
(1) how
All of the questions should be answered for a report to be complete.
The more complete the answers the more valuable the data is for problem-solving.
