The 4A's of Marketing document outlines four key factors - Acceptability, Affordability, Accessibility, and Awareness - that determine customer value from a product or service. Acceptability refers to a product meeting customer needs and expectations. Affordability means customers can afford and are willing to pay for a product. Accessibility is when customers can easily buy and use a product. Awareness is when customers have enough information about a product's features, benefits, and brand.
