Answer:
Encirclement attack.
Step-by-step explanation:
This term started to be used as a war strategy in which you attack your enemy, your opponent on all major fronts. Therefore, you encircle them. It's use in the market system is rather similar, given that you launch a product that covers all needs. For example, if your opponent firm or business creates a hair product that cleans and leaves the hair shiny, an encirclement attack would create one that cleans, leaves the hair shiny, smells better and is cheaper. That way you attack on "all major fronts".
