People are Strange, right? The decision model for buying varies for every user. This diagram (and 3 or 4 others like it) were used to describe how people act out their new purchase; becoming aware, doing authoritative-source research, grassroots research, they consider their purchase, make choices on specific product-spec level aspects of the purchase, they shop, and they purchase.
