Final answer:
Product-communication adaptation (dual adaptation) is the strategic approach where a product is customized for local tastes but retains the original branding and promotional strategies.
Step-by-step explanation:
The strategic alternative where the product is adapted to local preferences while the home-market promotional strategy or brand name is used is known as Product-communication adaptation (dual adaptation). In this strategy, businesses maintain their original brand identity and promotional approach while making adaptations to the product itself to suit the local tastes and preferences of the market they are entering. This approach recognizes that while a strong brand and established marketing strategy can be effective globally, some product modifications may be necessary to meet the specific needs and desires of consumers in different regions.
