What does the term "goal completion rates" refer to in walkthrough analysis?

The term "goal completion rates" specifically refers to the rate at which users successfully complete the intended tasks as outlined in a walkthrough. This metric is essential in analyzing the effectiveness of a walkthrough because it indicates how well users are navigating through the guide and achieving the desired outcomes set by the designer.

By focusing on users' task completion, this metric helps in understanding whether the walkthrough is intuitive and useful. High goal completion rates suggest that users are finding the information or assistance they need effectively, which can lead to better user engagement and satisfaction. Conversely, low completion rates may highlight issues within the walkthrough, such as confusing content or poor navigation, prompting the need for adjustments to improve overall user experience.

The other options, while potentially relevant in different contexts, do not capture the specific focus of goal completion rates concerning user task achievement within walkthroughs.
