System Analysis and Design - Chapter 10

Analysts must assume that users have read the manual, have attended the training classes, and have external help nearby.

False

Guidelines for aesthetics require that as much information as possible be squeezed onto a page or a screen with a minimum of white space; this will make the form or report pleasing to the eye and extremely functional.

False

The goal of the input mechanism is to present information to users so they can accurately understand it with the least effort, usually by understanding how reports will be used and designing them to minimize information overload and bias.

False

Using the word "client" repeatedly, instead of interchanging it with the word "customer" is an example of the interface design principle for minimal user effort.

False

Steve Krug provides us with a set of guiding principles for web usability. Find one of the principles in the following list

The user should never have to think about how to navigate the user interface.

A heuristic evaluation involves members of the project team individually working through the interface design prototype to examine each interface to see that it satisfies each design principle on a formal checklist.

True

A significant drawback of a printed report is the inability of the information to be further manipulated (i.e., sorted).

True

A use scenario is an outline of the steps that the users perform to accomplish some part of their work.

True

All forms and reports need a minimal amount of white space that is intentionally left blank.

True

All parts of the interface, whether navigation, input, or output, should provide as much content awareness as possible, but it is particularly important for forms or reports that are used quickly or irregularly.

True

Content awareness is the user interface design principle that requires that the screen design make it clear to the user what content is being displayed.

True

Input design means designing the screens used to enter the information, as well as any forms on which users write or type information (e.g., time cards, expense claims).

True

One of the challenges of designing user interface for mobile computing applications is that the device may be used everywhere.

True

One of the principles for common sense based user interface design is "Don't make me think!"

True

Pull-based approach can be used together with push-based approach for designing social media websites.

True

The three fundamental parts of the system interface are the navigation mechanism, the input mechanism, and the output mechanism, all of which are closely intertwined.

True

A(n) _____ check is a type of input validation that determines if several fields have been entered before the form can be processed.

completeness

A(n) _____ check ensures that combinations of data are valid, for example, does the zip code of an address correspond to the correct state name.

consistency

_____ assures the interface will act as the users expect, while _____ assures it will look pleasing.

consistency, aesthetics

The user interface design principle that places an emphasis on the user's ability to always know where he/she is in the system and what information is being displayed is _____.

content awareness

In user interface design, use scenarios will _____.

describe the most frequent paths taken through the use cases

Novice users prefer _____ while expert users prefer _____.

ease of learning, ease of use

As an addition to a regular report, a(n) _____ report may help the user understand the change in comparison values over time or show proportions that are relative to the whole.

graph

The fundamental part of the user interface that permits the system to capture information is the _____ mechanism.

input

The user interface design principle that places an emphasis on the intuitive flow of the interface (i.e. left to right and top to bottom) to minimize the user's movements is _____.

layout

The _____ design principle requires that a report not provide all the available information, only the information that is needed.

manage information load

If real-time information is required by the information system, then the appropriate input processing mechanism is _____.

on-line processing

The fundamental part of the user interface that provides information from the system to the user is the _____ mechanism.

output

One of the guidelines for designing user interfaces for social media website is to make sure you understand the difference between push and pull approaches. The push-based approach is __________.

the server sends information to users periodically

Which of the following interface evaluation techniques involves a highly structured assessment of the users' interaction with the system?

usability testing
