What does the "T" in HEART represent?

The "T" in HEART stands for Task success, which is a critical measure in user experience and design evaluations. It focuses on how effectively users can complete specific tasks within a system, emphasizing the importance of achieving desired outcomes during interactions. Task success is an indicator of usability, as it helps quantify how well a system meets the needs and expectations of its users. By assessing task success, organizations can identify areas for improvement, ensuring that systems are aligned with user goals and enhancing overall satisfaction.

While other options, such as trackability or technical expertise, may relate to aspects of usability or project success, they do not specifically capture the core concept represented by "T" in HEART.
