Oral or informal
Collection of data begins at home; an idea or a
thought is generated by the reactions of family members or friends in the
neighborhood. Ideas are also generated or reinforced during morning walks,
air/train/bus travel, at market places, canteen and other public places. Common
official channels like in-box documents, personal files, meeting records, etc.
provide ample data to support the idea.
