Answer: Strategic group
Step-by-step explanation:
A strategic group is a term used in management in where companies within an industry which have identical business models or identical combinations of strategies are grouped together.
For example, in the question above, Good deals, Home savings, King's bargain and Hank's store are all departmental stores they offer similar services.
Strategic group analysis helps in the identification of a company's direct competitors and can also help in the identification of opportunities.
