How do you evaluate the feedback from a cognitive walkthrough?

由人工智能和领英社区提供技术支持

A cognitive walkthrough is a usability evaluation method that simulates how a user would interact with a system or a product. It involves a team of evaluators who follow a predefined scenario and try to perform the tasks that the user would do. The evaluators assess how easy or difficult it is to achieve the goals, and identify any potential problems or errors. In this article, you will learn how to conduct a cognitive walkthrough in the context of usability engineering, and how to evaluate the feedback from the method.

1 Define the Scope and the Goals

The first step in conducting a cognitive walkthrough is to define the scope and the goals of the evaluation. You need to decide what aspects of the system or the product you want to test, and what are the expected outcomes. You also need to define the target users, their characteristics, and their needs. This will help you to create realistic scenarios and tasks that reflect the user's perspective and context.

Evaluate feedback from a cognitive walkthrough by identifying recurring usability issues ???♂?. Prioritize findings based on their impact on user tasks and experiences. Look for patterns in user misunderstandings or errors. Consider the alignment of feedback with design goals and objectives ??. Analyze feedback qualitatively and quantitatively to gauge the severity and frequency of issues. Use insights to refine the design iteratively and enhance usability. ????

2 Create Scenarios and Tasks

The next step is to create scenarios and tasks that the evaluators will follow during the cognitive walkthrough. A scenario is a description of a situation or a problem that the user wants to solve using the system or the product. A task is a series of actions that the user needs to perform to achieve the goal of the scenario. You should create multiple scenarios and tasks that cover different features and functions of the system or the product, and vary in complexity and difficulty.

Try to be as concrete and specific as possible here. When outlining or starting out it's fine to be vague or attitudinal, but that won't get your analysis far later on. So sweat the details. Use bullet points instead of long, grammatically correct paragraphs. Based on what you'll be evaluating for, create straightforward scales for your evaluators to use to help them do their work efficiently. And let them say they don't know how to interpret some data! It may just need someone else's eyes to make sense.

3 Select Evaluators and Roles

The third step is to select the evaluators and assign them roles for the cognitive walkthrough. You need at least one evaluator who will act as the user, and one evaluator who will act as the facilitator. The user will perform the tasks according to the scenarios, while the facilitator will guide the user and ask questions. You can also have other evaluators who will act as observers, note-takers, or experts. The evaluators should have some knowledge of the system or the product, but not be too familiar with it.

4 Conduct the Cognitive Walkthrough

The fourth step is to conduct the cognitive walkthrough. The facilitator will present the scenario and the task to the user, and ask them to think aloud as they interact with the system or the product. Additionally, the facilitator will ask four questions for each action that the user performs in order to determine if they know what to do next, if they notice that the correct action is available, if they associate the correct action with the goal, and if they get feedback that their action was successful. The evaluators will record the user's actions, answers, comments, and any problems or errors that occur, noting any positive or negative aspects of the system or product.

Recently, I facilitated a cognitive walkthrough for a new app we were developing. I asked users to complete tasks while thinking out loud, like changing their profile settings. I observed if they understood what to do next and noticed available options. One user hesitated on a screen, which revealed a usability issue, and mentioned that the confirmation message after saving changes wasn’t clear. This feedback helped identify areas for improvement, such as making options more visible and providing clearer feedback, leading to a more intuitive design.

5 Evaluate the Feedback and Generate Recommendations

The final step is to evaluate the feedback and generate recommendations for improving the usability of the system or the product. The evaluators will review the notes and the recordings from the cognitive walkthrough, and identify any issues or patterns that emerged. They will also rate the ease or difficulty of each task, and the satisfaction or frustration of the user. Based on the findings, the evaluators will suggest possible solutions or changes that could enhance the user experience and the performance.
