Question 1

Core Process 3 involves defining in great detail what the information system needs to accomplish in order to provide the organization with the desired benefits.

Accepted Answer

Core Process 3, also known as Define the Requirements, is focused on defining the specific functions and features the information system must include in order to meet the organization's needs and achieve its goals. This process involves detailed analysis of the organization's existing processes and systems, identification of key requirements and user needs, and development of a comprehensive requirements document that outlines the system's functionality, performance, and other key factors.

Question 2

The reason an analyst uses many different models is that each relates to a different aspect of the system.

Accepted Answer

Different models can be used to represent different aspects of a system, such as data flow, functional behavior, or structural organization. Using multiple models allows the analyst to better understand and analyze the system from multiple perspectives.

Question 3

When observing business processes,it is not necessary to observe all the processes at the same level of detail.

Accepted Answer

It is important to prioritize and focus on the key processes that have the greatest impact on the organization, rather than trying to observe every single process in detail.

Question 9

Asking about error conditions usually is done in later interviews after the analyst understands and documents the basic processing requirements.

Accepted Answer

The answer of Asking about error conditions usually is done...

Question 10

Textual models are used to represent precise aspects of the system that can be best represented by using formulas.

Accepted Answer

Textual models are typically used to describe qualitative aspects of a system, while precise aspects that can be represented by formulas are often better suited for mathematical or computational models.

Question 11

The term "I'll know it when I see it" applies to one valid way to get requirements definition.

Accepted Answer

"I'll know it when I see it" is a valid way of requirements definition, often used in situations where stakeholders are not able to articulate their needs clearly or where requirements are difficult to capture in a concrete way. This approach involves demonstrating prototypes or mockups to stakeholders and allowing them to provide feedback until the desired outcome is achieved.

Question 12

Question 16

A decision point within an activity diagram may be shown with an activity symbol.

Accepted Answer

A decision point or conditional statement in an activity diagram is represented by a diamond-shaped symbol.

Question 17

A fact finding user interview can usually be completed in one comprehensive session.

Accepted Answer

A fact finding user interview usually involves gathering detailed information about the user and their needs, which can take more than one session to complete thoroughly.

Question 18

A synchronization bar in an activity diagram allows multiple agents or actors to participate in a workflow in separate rows.

Accepted Answer

A synchronization bar in an activity diagram is used to synchronize multiple flows into one or split a single flow into multiple concurrent flows, rather than to represent multiple agents or actors in separate rows.

Question 20

Systems analysis involves the creation of logical models.

Accepted Answer

Systems analysis typically involves the creation of logical models such as data flow diagrams, entity-relationship diagrams, and decision trees to help understand and describe the structure and behavior of the system being studied.
