STP _ Segmentation, Targetting and Positioning.
For example, retail supermarkets where the offering varies -price, experience or quality, as does the pricing for near identical products
Although segmentation is often seen in this light, other factors come into play such as demographics, although these are not effective in capturing identity.
The segment that the retailer chooses to serve is the target market(s).
The final STP is to position the product in relation to competitor products.
