Answer: (c).To critique the system's usability and construct a coherent story Explanation:The evaluators step through the action sequence to critique the system's usability and tell a believable story about its usability.
Q22.
What is the primary focus of the cognitive walkthrough technique?

a.

Identifying potential programming errors

b.

Assessing the system's efficiency and performance

c.

Evaluating users' emotions during interaction

d.

Evaluating the ease of learning and usability of the system

Discuss
Answer: (d).Evaluating the ease of learning and usability of the system Explanation:The primary focus of the cognitive walkthrough technique is evaluating the ease of learning and usability of the system for users.

What is the primary purpose of documenting a cognitive walkthrough?

a.

To provide a record of the evaluators' personal preferences

b.

To track the progress of the system's implementation

c.

To identify coding errors and inconsistencies

d.

To record design strengths and areas needing improvement

Discuss
Answer: (d).To record design strengths and areas needing improvement Explanation:Documenting a cognitive walkthrough helps to record the design's strengths and areas needing improvement for future reference and action.
Q24.
What purpose does a separate usability problem report sheet serve in a cognitive walkthrough evaluation?

a.

To provide an overview of the system's design

b.

To list the features of the system that work well

c.

To identify all the coding errors in the system

d.

To document identified usability problems with details and severity

Discuss
Answer: (d).To document identified usability problems with details and severity Explanation:A usability problem report sheet is used to document identified usability problems along with their details and severity.
Q25.
How can information about the severity of a usability problem help designers?

a.

It helps designers identify coding errors in the system.

b.

It helps designers prioritize which problems to address first.

c.

It provides a summary of the overall usability of the system.

d.

It determines the date and time of the next cognitive walkthrough.

Discuss
Answer: (b).It helps designers prioritize which problems to address first. Explanation:Information about the severity of usability problems helps designers prioritize which problems to address first, as it may not be feasible to fix every problem immediately.
Q26.
What is the role of standard evaluation forms in a cognitive walkthrough?

a.

To replace the need for evaluators' input in the process

b.

To provide a summary of the system's coding structure

c.

To standardize the process and record relevant information

d.

To assess the emotional response of users during interaction

Discuss
Answer: (c).To standardize the process and record relevant information Explanation:Standard evaluation forms help standardize the process, capture relevant information, and provide a consistent way to document the cognitive walkthrough results.
Q27.
What is a heuristic in the context of heuristic evaluation?

a.

A set of complex algorithms used for user testing

b.

A type of graphical user interface element

c.

A guideline or rule of thumb for design decisions and evaluation

d.

A specific type of user error often encountered in testing

Discuss
Answer: (c).A guideline or rule of thumb for design decisions and evaluation Explanation:A heuristic in the context of heuristic evaluation refers to a guideline or rule of thumb that can guide design decisions or be used to evaluate design choices.
Q28.
What is the primary purpose of heuristic evaluation?

a.

To test the system's functionality with real users

b.

To critique a system using a set of specific algorithms

c.

To independently assess the effectiveness of visual design

d.

To identify potential usability problems based on heuristics

Discuss
Answer: (d).To identify potential usability problems based on heuristics Explanation:The primary purpose of heuristic evaluation is to identify potential usability problems by critiquing a system using a set of general heuristics.
Q29.
What does Nielsen's recommendation suggest about the number of evaluators for heuristic evaluation?

a.

One evaluator is sufficient for comprehensive results.

b.

A minimum of three evaluators is necessary for reliable results.

c.

A single evaluator must cover a wide range of heuristics.

d.

More than five evaluators are required for meaningful results.

Discuss
Answer: (b).A minimum of three evaluators is necessary for reliable results. Explanation:Nielsen's recommendation is that between three and five evaluators are sufficient for heuristic evaluation, with five usually discovering around 75% of the usability problems.
Q30.
How are the severity ratings of usability problems determined in heuristic evaluation?

a.

Based on the number of evaluators' opinions

b.

Calculated using a complex mathematical formula

c.

Derived from the average user satisfaction scores

d.

Evaluated using factors like commonality and impact

Discuss
Answer: (d).Evaluated using factors like commonality and impact Explanation:Severity ratings of usability problems in heuristic evaluation are assessed based on factors such as how common the problem is, how easy it is for users to overcome, its frequency, and how seriously it's perceived.
