Final answer:
An executive is most likely to include the proposed customer value proposition in a new-product idea write-up, as it is vital in determining the product's potential appeal and success.
Step-by-step explanation:
When an executive writes up a new-product idea to be presented to a new-product committee, they are most likely to include the proposed customer value proposition. The customer value proposition outlines the unique value that the product will deliver to customers, which is a crucial aspect in the initial assessment of a product's potential success. While other components like the product image, marketing strategy, business analysis, and planned market rollout are essential, they are typically developed after the product concept has been approved based on its value proposition.
