Which method is used to analyze users’ actions and behaviors across various tasks?

The correct answer is task analysis because this method specifically focuses on breaking down the actions and behaviors of users as they engage in various tasks. Task analysis involves understanding the steps that users take to accomplish their goals, including the strategies they use, the decisions they make, and the tools or resources they utilize. This analysis can help identify areas for improvement in a system or process by making it clearer how users interact with a particular task.

Behavioral analysis, while related, generally focuses more broadly on patterns in users' behaviors rather than the detailed actions taken to complete specific tasks. Process mapping involves outlining the steps in a process but does not specifically analyze individual user actions or behaviors in the detailed way that task analysis does. Usability assessment evaluates how easy a system is to use, including user satisfaction and efficiency, but does not primarily focus on the detailed analysis of user actions and behaviors across tasks.
