True

False

The output of the interviewing process

The work plan

The model that is produced by extreme prototyping

The expanded and thoroughly balanced use case for a system

A formal way of representing how a business system operates

Models that describe processes without suggesting how they are conducted

Coded logic models

Models based upon implementing the if-then-else programming structure

Developed by the infrastructure analyst

Created in the system walkthough

Use cases are developed by users and data flow diagrams are developed by systems analysts

Data flow diagrams are developed first and then use cases ensue

Use cases are developed first and then data flow diagrams ensue

Use cases show logical processes, while data flow diagrams show physical processes

There is not a relationship between use cases and data flow diagrams

This is an error as there needs to be the same amount of inputs as outputs

This is an error as process do not have inputs or outputs

This is normal as all processes have two inputs and one output

This is normal as all processes need at least one input and at least one output

This is an error as processes only produce output

Use cases tend to be developed with users to make sure the analyst has fully captured the processes and relationships; DFD's are built upon the use cases to more fully formally understand the processes involved

Both are tools in a systems analysts toolbox, although they do unrelated things

Use cases are developed by users exclusively; while DFD's are developed by analysts exclusively

Use cases come out of JAD sessions and clarify what was discussed by users in those sessions; DFD's come out of analysts' interviews.

They are the same thing – use cases are process models using the DeMarco and Yourdon notation; and DFD's are process models using the Gane and Sarson notation.
