McDonald's conducting a focus group to gauge customer reactions to a new product line is known as?

The correct choice pertains to the process of evaluating customer reactions to an idea or concept before a product is fully developed and marketed. Concept testing involves presenting a new product or idea to a select group of potential consumers, such as through focus groups, to gather feedback on their perception, preferences, and attitudes. This stage is critical in ensuring that the product aligns with customer needs and market demands, decreasing the risk of unsuccessful launches.

In contrast, market testing generally refers to assessing a newly developed product in a real market environment to observe its performance against competitors and gather sales data. Product development encompasses the entire process of bringing a new product from idea to market, which includes concept development and testing phases. A feasibility study examines the potential success and viability of a product idea or business project but does not specifically focus on gauging customer reactions like concept testing does.
