CUA Heuristic Evaluation & Expert Review 3

Question 1

According to Nielsen's research, approximately what percentage of a product's usability problems can be found by a single expert evaluator?

Accepted Answer

Around 35%

Answer

Nielsen's research shows that a single evaluator typically finds approximately 35% of usability problems, reinforcing the need for multiple evaluators.

Question 2

Which of the following is a key limitation of heuristic evaluation compared to usability testing with users?

Accepted Answer

It may miss problems that only emerge from real user behavior and context

Answer

Because heuristic evaluation uses experts rather than real users, it can miss problems that only become apparent when actual users interact with the system in their natural context.

Question 3

When applying the heuristic 'Recognition rather than recall,' which design approach best satisfies this principle?

Accepted Answer

Making objects, actions, and options visible rather than requiring users to remember them

Answer

Recognition rather than recall means the interface should surface relevant information and options so users don't have to remember what to do — reducing cognitive load.

Question 4

A UX team wants to evaluate a competitor's product without having user access. Which expert review method is most appropriate?

Accepted Answer

Heuristic evaluation by internal usability experts

Answer

Heuristic evaluation by internal experts can be conducted on any interface — including competitors' — without requiring access to that company's users or internal systems.

Question 5

In Nielsen's severity rating system, a rating of '0' means:

Accepted Answer

The evaluator does not agree it is a usability problem at all

Answer

Severity 0 means the evaluator does not consider it a usability problem — it is used to record items reviewed but not classified as violations.
