Which term refers to customers having a need or want for a product?

Desirability is the term that encapsulates customers’ needs or wants for a product. In the context of UX design and product development, desirability focuses on understanding what makes a product appealing to users, compelling them to engage with it. This is crucial because identifying what customers desire helps guide design decisions and ensures that the product meets the emotional and functional needs of the target audience.

In contrast, viability relates to a product's capability to succeed within the market and contribute to the business's goals, while feasibility addresses whether a product can be realistically developed with the available resources and technology. Integrity is not directly associated with user needs but rather concerns the quality and consistency of the design or product. Therefore, desirability is the key concept connected to the attraction and demand that customers exhibit towards a product.
