Why usability is important to you. Usability is the measure of the quality of a user's experience when interacting with a product or system-whether a web site, software application, mobile technology, or any user-operated device.
In general, testing falls into two categories: evaluation by usability experts, and testing that involves real users. Experts will evaluate a system according to proven usability principles, by analyzing the environment in which itâs used, and by the application of special software tools such as Cogtool. With user-based testing, on the other hand, trained observers watch users work with an EHR, or ask users for feedback after or while they are using the system (using surveys, focus groups, talk-aloud techniques, etc.).
