Which concept refers to how well a product achieves its goals in a given context?

The concept that refers to how well a product achieves its goals in a given context is effectiveness. Effectiveness is a measure of the degree to which a product or system successfully meets its intended objectives or fulfills the needs of its users. It takes into account the overall success of the functionality and usability of the product within the specific environment where it is employed.

While usability, for instance, focuses on how user-friendly and easy to navigate a product is, effectiveness goes further to evaluate whether the desired outcomes are actually accomplished when the product is used in real-world scenarios. In the context of health informatics, a product may be very usable, but if it does not effectively facilitate better health outcomes, its value is diminished. Therefore, assessing effectiveness is crucial to determine if the goals of improving health care delivery, patient outcomes, or operational efficiency are achieved.
