Hunt for the object

I want to write on an important idea that Grady Booch had still looking for stuff on its source.
He hinted at a question on how to find objects from a story for the code. Perhaps i could analyse and extend that idea.I have found some pointers worth considering as well as read the chapter in his book Object Oriented Analysis and Design with applications pp 150.

There are three main methods to elicit the story :

1. q
2. a
3. c

later there have been various developments on the subject including CRC cards, GRASP.
