What process involves observing users interacting with a system to improve it?

The focus on observing users interacting with a system to improve it aligns with usability testing. This process typically involves collecting qualitative data on how users navigate and utilize the system’s features. By observing user behavior, feedback can be gathered on specific aspects such as ease of use, accessibility, and overall user experience. This information is critical as it informs necessary adjustments and enhancements to the system, ultimately leading to a more user-centered design.

In contrast, task analysis centers on understanding the tasks users need to complete and breaking those tasks down into steps, but it does not inherently involve real-time observation of the users' interactions. Data migration refers to transferring data between storage types, formats, or systems, while quality assurance encompasses systematic evaluations to ensure the quality of products or services, but they do not focus specifically on observing user interaction for improvement purposes. Thus, usability testing is the correct process associated with observing users to enhance system functionality.
