Graphical models are most useful in requirements specification when you need to:

Show how a system state changes, or describe a sequence of actions in response to an event or message

Describe organizational policies that constrain the development process

Define the budget and schedule for the project

Write detailed mathematical proofs about system correctness

Correct Answer

Show how a system state changes, or describe a sequence of actions in response to an event or message

Explanation

Graphical models are most useful when you need to show how a state changes or when you need to describe a sequence of actions. UML sequence charts and state charts show the sequence of actions that occur in response to a certain message or event.
