Final answer:
An analogy to the value proposition of "effectiveness" in marketing is comparing cost per unit or characteristics of products.
Step-by-step explanation:
An analogy to the value proposition of "effectiveness" in the marketing discipline could be using the comparison of cost per unit in the grocery store or characteristics of one product versus another. When individuals compare these factors, they are evaluating the effectiveness of the products and making decisions based on their perceived value.
For example, if a consumer is comparing two laundry detergents and one claims to be more effective at removing stains, they may choose that product because they believe it will provide better results. The value proposition of effectiveness in marketing is about convincing consumers that a product will deliver the desired outcome or benefit.
