Kipling Six Ws / 6 W's / 5W1H
Rudyard Kipling, English Nobel Prize winner for Literature (1907) writer and poet, known for his tales and tales and poems of British soldiers in India and for "The Jungle Book" (the story about little boy Mowli being raised by wild animals), expanded this set of 5 W questions to help trigger ideas and solve problems and added one H (or you can also count is as the 6th W if you forgive it is not the first letter, but the last) and immortalized them in his poem "Just So Stories/The Elephant's Child":
I keep six honest serving-men ;
(They taught me all I knew)
Their names are What and Where and When
And How and Where and Who.
I send them over land and sea,
I send them east and west;
But after they have worked for me,
I give them all a rest.
I let them rest from nine till five,
For I am busy then,
As well as breakfast, lunch, and tea,
For they are hungry men:
But different folk have different views:
I know a person small—
She keeps ten million serving-men,
Who get no rest at all!
She sends 'em abroad on her own affairs,
From the second she opens her eyes—
One million Hows, two million Wheres,
And seven million Whys!
