Q71.
What does the "best case" value for a usability attribute represent?

a.

The lowest acceptable measurement for the attribute.

b.

The highest acceptable measurement for the attribute.

c.

The target value for the attribute in the design.

d.

The best possible measurement given the current state of development tools and technology.

Discuss
Answer: (d).The best possible measurement given the current state of development tools and technology. Explanation:The "best case" value for a usability attribute represents the level that is agreed to be the best possible measurement given the current state of development tools and technology.
Q72.
What are usability metrics?

a.

The measurement criteria for a usability attribute.

b.

The values for the now level and planned level of a usability attribute.

c.

The best and worst case values for a usability attribute.

d.

The user actions required to perform an undo operation.

Discuss
Answer: (a).The measurement criteria for a usability attribute. Explanation:Usability metrics are the measurement criteria for a usability attribute.
Q73.
What is the major feature of usability engineering?

a.

Relying on measurements of very specific user actions.

b.

Setting goals for measured observations based on specific user actions and situations.

c.

Using usability metrics to judge a system's usability once it is delivered.

d.

Providing a means of satisfying usability specifications.

Discuss
Answer: (c).Using usability metrics to judge a system's usability once it is delivered. Explanation:The major feature of usability engineering is the use of usability metrics to judge a system's usability once it is delivered.
Q74.
What is a problem with usability metrics at early stages of design?

a.

They rely on measurements of very specific user actions.

b.

They do not provide a predictive design process for usability.

c.

They assume the availability of specific features like undo buttons.

d.

They focus on specific user actions and situations that may not be known yet.

Discuss
Answer: (d).They focus on specific user actions and situations that may not be known yet. Explanation:A problem with usability metrics at early stages of design is that they focus on specific user actions and situations that may not be known yet by the designers.
Q75.
What is a limitation of usability engineering?

a.

It focuses on satisfying usability specifications rather than actual usability.

b.

It relies too heavily on empirical approaches.

c.

It cannot measure user performance accurately.

d.

It is not applicable to interactive systems.

Discuss
Answer: (a).It focuses on satisfying usability specifications rather than actual usability. Explanation:A limitation of usability engineering is that it provides a means of satisfying usability specifications and not necessarily usability itself.
Q76.
Why does usability engineering not necessarily guarantee usability for real people?

a.

It relies on measurements of very specific user actions.

b.

It does not provide a predictive design process for usability.

c.

It does not take into account the reasons behind specific usability metrics.

d.

It assumes the availability of specific features without understanding user needs.

Discuss
Answer: (c).It does not take into account the reasons behind specific usability metrics. Explanation:Usability engineering may not guarantee usability for real people because it does not necessarily take into account the reasons behind specific usability metrics, such as the assumption that fewer explicit actions make the undo operation easier.
Q77.
Which approach to prototyping involves building a prototype and then using the design knowledge gained to build the final product, discarding the actual prototype?

a.

Incremental

b.

Evolutionary

c.

Throw-away

d.

None of the above

Discuss
Answer: (c).Throw-away Explanation:The approach to prototyping that involves building a prototype and then using the design knowledge gained to build the final product, discarding the actual prototype, is called "throw-away" prototyping.
Q78.
In the incremental approach to prototyping, how is the final product built?

a.

All components are built simultaneously.

b.

The final product is built as a single component.

c.

The final product is built as separate components, one at a time.

d.

The final product is built based on the throw-away prototype.

Discuss
Answer: (c).The final product is built as separate components, one at a time. Explanation:In the incremental approach to prototyping, the final product is built as separate components, one at a time. Each subsequent release includes one more component until the final system is complete.
Q79.
Which prototyping approach involves using the prototype as the basis for the next iteration of design, and the actual system evolves from an initial limited version to its final release?

a.

Incremental

b.

Evolutionary

c.

Throw-away

d.

Both a and b

Discuss
Answer: (b).Evolutionary Explanation:The prototyping approach that involves using the prototype as the basis for the next iteration of design and seeing the actual system as evolving from an initial limited version to its final release is called "evolutionary" prototyping.
Q80.
What is the main purpose of iterative design?

a.

To create a final product that is built as separate components.

b.

To build a throw-away prototype for testing and discarding.

c.

To overcome the problems of incomplete requirements specification by cycling through several designs, incrementally improving the final product with each pass.

d.

To evolve the prototype into the final system by making modifications during the operation and maintenance activity.

Discuss
Answer: (c).To overcome the problems of incomplete requirements specification by cycling through several designs, incrementally improving the final product with each pass. Explanation:The main purpose of iterative design is to overcome the problems of incomplete requirements specification by cycling through several designs, incrementally improving the final product with each pass.
