ISTM 320 Exam 3 ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
Project Triangle Defined by three interactive legs: Cost, Scope, and Time. A change in one leg
affects the other two.
According to Microsoft, what should a PM find when a The 'stuck side' of the triangle, the side (cost, scope, or time) that is fixed and
project is at risk? unlikely to change.
User Interface (UI) Describes how users interact with a computer system, including all hardware,
software, screens, menus, functions, output, and features affecting two-way
communication.
Human-Computer Interaction (HCI) The relationship between computers and those who use them. Includes all
communications needed to enter input and obtain output.
Name the main types of HCI methods. GUIs, command-line interfaces (CLIs), touch interfaces, voice user interfaces
(VUIs), gesture-based, and AR/VR.
A UI that does not distract the user and calls no attention Transparent
to itself is described as _ _.
List the seven habits of successful interface designers. (1) Understand the business, (2) Maximize graphical effectiveness, (3) Think like a
user, (4) Use models and prototypes, (5) Focus on usability, (6) Invite feedback,
(7) Document everything.
List the 10 guidelines for UI design. (1) Easy to learn/use, (2) Enhance productivity, (3) Provide flexibility, (4) Provide
help/feedback, (5) Attractive layout, (6) Enhance the interface, (7) Focus on data
entry screens, (8) Use validation rules, (9) Manage data effectively, (10) Reduce
input volume.
A tool that visually represents business functions in a Functional Decomposition Diagram (FDD)
hierarchy is called a(n) _.
Storyboarding A design tool that presents initial screen designs as a series of sketches to
facilitate early user involvement.
An initial screen with command buttons for navigating the Switchboard
system is called a _ _.
A template or pattern that restricts data entry and Input mask
prevents errors is a(n) _ _.
, Garbage In, Garbage Out (GIGO) Output quality is only as good as input quality. The best time to avoid problems is
when data is entered.
Source document A document that collects input data, triggers or authorizes an input action, and
provides a record of the original transaction.
Name the zones of a source document. Heading, control, instruction, body, totals, and authorization zones.
Data validation rule A rule that improves input quality by testing data and rejecting entries that fail to
meet specified conditions.
Name the eight types of data validation checks. Sequence, existence, data type, range, reasonableness, validity, combination, and
batch controls.
Validation rule: Sequence check Used when data must be in a predetermined sequence (e.g., work orders in
numerical order).
Validation rule: Existence check Tests whether a required field has been left empty.
A(n) _____ check verifies that a value falls within a specific Range
minimum and maximum.
Validation rule: Reasonableness check Identifies values that are questionable but not necessarily wrong (e.g., a $5M
payment passes range checks but seems unusual).
Validation rule: Validity check Verifies that a data item matches a valid set of values. Also called referential
integrity.
Totals used to verify batch input that aren't necessarily Hash totals (batch controls)
meaningful as sums are called _.
Report type: Detail Produces one or more lines of output for every record processed.
Report type: Exception Displays only records that meet specific conditions or require action.
Report type: Summary Provides total figures for upper-level managers without supporting details.
A _____ occurs when the value of a control field changes, Control break
triggering subtotals.
Name the standard report components. Report header/footer (beginning/end of report), page header/footer
(top/bottom of page), and grouping/totals.
System Prototyping Produces a full-featured working model with advanced interactivity, animations,
and transitions (high-fidelity).
