Thank you for your input. If i did understand those Jargon theory i would not have asked to give one simple example.. rather than a lot of theory.

Extract requirements: what you actually do in real business to extract requirement ??? do you use software tools or how you extract requirement that was my question.

Anticipate requirements: how you really Anticipate requirements in real business??????

i understand if some one say go and cook rice. i know i need rice, water and electricity or gas whatever means i used to cook rice. but may be i don't know where and how to buy rice is not it?? Ya I know this is a dumb question but out of curiosity what do i need to do as a business analyst in real field not is theoretical world.

Thanks
