Questions: At which stage in the new product development process does the company have a number of ideas that it thinks might work and gets customers' feedback as to which ideas sound most promising?

The answer is: concept testing.

Explanation for each option:

• Design Development: This stage involves creating detailed designs and prototypes of the product. It occurs after concept testing and focuses on refining the product's design.

• Concept Testing: This is the stage where the company has several ideas and seeks customer feedback to determine which concepts are most promising. It helps in evaluating the potential success of a product before significant resources are invested.

• Idea Generation: This is the initial stage where a company brainstorms and gathers a wide range of ideas for new products. It precedes concept testing and does not involve customer feedback.

• Product Launch: This is the final stage where the product is introduced to the market. It occurs after all development and testing phases are complete.
