Which product characteristic indicates how well a product meets consumer needs?

The characteristic that indicates how well a product meets consumer needs is compatibility. When a product is compatible, it means that it aligns well with the preferences, values, and existing practices of consumers. High compatibility suggests that the product can easily be integrated into the consumers' lives without significant changes to their behavior or routines, making it more likely to satisfy their needs effectively.

In contrast, relative advantage pertains to how a product is perceived as better than competitors, complexity refers to how difficult a product is to understand or use, and trialability involves how easily a product can be tested or sampled by potential customers. While these factors can influence the overall success of a product, compatibility directly addresses the alignment between the product characteristics and consumer expectations, which is crucial for meeting those needs.
