Q31.
Which severity rating implies the highest urgency for fixing a usability problem in heuristic evaluation?

a.

0 = I don’t agree that this is a usability problem at all

b.

1 = Cosmetic problem only: need not be fixed unless extra time is available on project

c.

2 = Minor usability problem: fixing this should be given low priority

d.

4 = Usability catastrophe: imperative to fix this before product can be released

Discuss
Answer: (d).4 = Usability catastrophe: imperative to fix this before product can be released Explanation:Severity rating 4 indicates a "Usability catastrophe," which means the problem is imperative to fix before the product can be released.
Q32.
Which heuristic emphasizes the importance of keeping users informed about the system's operations in a timely manner?

a.

Error prevention

b.

Visibility of system status

c.

Match between system and the real world

d.

Consistency and standards

Discuss
Answer: (b).Visibility of system status Explanation:The heuristic "Visibility of system status" emphasizes the importance of keeping users informed about what is happening within the system. This involves providing appropriate feedback to users in a timely manner. For example, if a system operation takes some time to complete, the user should be given an indication of the progress and the amount completed. This helps users stay informed and reduces uncertainty during interactions.
Q33.
According to Nielsen's heuristic for "Match between system and the real world," how should the system communicate with the user?

a.

Using technical and system-oriented terms

b.

Following platform conventions and standards

c.

Speaking the user's language and using familiar concepts

d.

Using minimalistic design and aesthetics

Discuss
Answer: (c).Speaking the user's language and using familiar concepts Explanation:The heuristic "Match between system and the real world" suggests that the system should be designed to use language, words, phrases, and concepts that are familiar to the user. It should avoid using technical jargon and system-oriented terms that might confuse users. Instead, it should follow real-world conventions and present information in a natural and logical order that aligns with the user's understanding.
Q34.
What is the purpose of providing an "emergency exit" in a system, as per Nielsen's heuristics?

a.

To undo accidental user actions

b.

To provide a shortcut for experienced users

c.

To prevent errors from occurring

d.

To enhance the aesthetics of the interface

Discuss
Answer: (a).To undo accidental user actions Explanation:The heuristic "User control and freedom" emphasizes the importance of providing users with an "emergency exit" or a way to undo actions they might have taken by mistake. This helps users avoid being stuck in unwanted states without an option to backtrack or undo their actions. By offering control and freedom to the users, they can navigate the system confidently.
Q35.
Nielsen's heuristic of "Flexibility and efficiency of use" suggests allowing users to:

a.

Customize the visual appearance of the interface

b.

Access advanced system settings easily

c.

Tailor frequent actions and use accelerators

d.

Share their experience with other users

Discuss
Answer: (c).Tailor frequent actions and use accelerators Explanation:The heuristic "Flexibility and efficiency of use" recommends allowing users to customize their interactions by tailoring frequent actions. It also suggests providing accelerators that enable experienced users to perform tasks more efficiently. This approach accommodates both novice and expert users and improves overall usability.
Q36.
In the context of Nielsen's heuristics, what is the purpose of "aesthetic and minimalist design"?

a.

To include all available information in the dialog

b.

To prioritize irrelevant information for visibility

c.

To create an artistic and visually appealing interface

d.

To minimize unnecessary or rarely needed information

Discuss
Answer: (d).To minimize unnecessary or rarely needed information Explanation:The heuristic "Aesthetic and minimalist design" advises that dialogs and interfaces should avoid containing information that is irrelevant or rarely needed. Including unnecessary information can compete with relevant information and reduce its visibility, potentially confusing users. Aesthetic and minimalist design focuses on presenting only essential and relevant content.
Q37.
What is the recommended approach for expressing error messages, according to Nielsen's heuristics?

a.

Use error codes for precise identification

b.

Suggest multiple possible solutions to users

c.

Provide a long list of technical instructions

d.

Use plain language and suggest constructive solutions

Discuss
Answer: (d).Use plain language and suggest constructive solutions Explanation:According to the heuristic "Help users recognize, diagnose and recover from errors," error messages should be expressed in plain language that users can easily understand. The messages should precisely indicate the problem and provide constructive suggestions for how users can resolve the issue. Clear and informative error messages contribute to a positive user experience.
Q38.
Which heuristic suggests that help and documentation should be focused on the user's task and easy to search?

a.

Help users recognize, diagnose and recover from errors

b.

Consistency and standards

c.

Help and documentation

d.

Visibility of system status

Discuss
Answer: (c).Help and documentation Explanation:The heuristic "Help and documentation" suggests that while some systems may require user instructions, such information should be easy to search and focused on the user's tasks. The documentation should provide concrete steps that users can follow to achieve their goals. Clear and task-oriented help materials enhance user understanding and efficiency.
Q39.
After independent evaluations in heuristic evaluation, what is the next step in the process?

a.

Implementing all suggested changes immediately

b.

Ignoring the identified problems and continuing development

c.

Calculating mean severity ratings and prioritizing issues

d.

Comparing evaluations to determine the "expert" evaluator

Discuss
Answer: (c).Calculating mean severity ratings and prioritizing issues Explanation:After independent evaluations in heuristic evaluation, the next step involves collecting the identified usability problems and calculating the mean severity ratings for each problem. This step helps prioritize the identified issues based on their severity and potential impact on user experience. Issues with higher severity ratings are typically addressed with higher priority.
Q40.
What is the GOMS model used for in evaluation?

a.

Identifying usability problems in prototypes

b.

Evaluating the aesthetic design of interfaces

c.

Predicting user performance with an interface

d.

Analyzing the real-world context of user interactions

Discuss
Answer: (c).Predicting user performance with an interface Explanation:The GOMS (goals, operators, methods, and selection) model is used to predict user performance with a specific interface. It helps in assessing how users will interact with the interface and how efficiently they can achieve their goals.
