Final answer:
The men's clothing manufacturer is using a niche strategy according to Michael Porter's competitive strategies, focusing on a specific segment of the market and likely leveraging a well-respected brand name to cater to the unique needs of men shorter than 5'8" tall.
Step-by-step explanation:
The clothing manufacturer in Cleveland, Ohio, which has a low industry market share overall but a high market share within its target market of men shorter than 5'8" tall, is employing a competitive strategy that falls under Michael Porter's competitive strategies.
This particular strategy is known as a niche strategy. By focusing on a specific segment of the market, the manufacturer is able to cater to the unique needs of shorter men, providing tailored products that may not be readily available from other, more generalized clothing manufacturers.
In monopolistically competitive markets like clothing retail, which feature a large number of firms and differentiated products, focusing on a niche can be an effective way for a company to establish itself as a leader in a specific segment while facing less competition.
The manufacturer’s approach suggests that it's not competing on price or trying to appeal to a mass market but instead is concentrating on a well-defined customer group, possibly leveraging factors such as a well-respected brand name and a strong reputation within its niche.
