Non-usability

Non-usability refers to the state or condition where a product, system, or service is difficult or impossible to use effectively and efficiently. This can stem from various factors, including poor design, confusing interfaces, lack of intuitive features, technical glitches, or incompatibility with the user's needs or abilities. It signifies a failure in user experience (UX) and can lead to frustration, dissatisfaction, and ultimately, abandonment of the product or service. Non-usability is a critical concern in product development and necessitates thorough user testing and iterative design improvements to achieve a user-friendly and accessible outcome. It directly impacts the success of a product by hampering user adoption, efficiency, and overall satisfaction.
