True

Agile Modeling (AM) provides guidance to practitioner during which of these software tasks?

Analysis and Design

Agile Unified Process uses the classic UP phased activities (inception, elaboration, construction, transition) to help the team visualize the overall process flow. T/F

True

The data flow diagram

Depicts functions that transform the data flow

Indicates how data are transformed by the system

Control flow diagrams are

Needed to model event driven systems

The control specification represents the system behavior using UML sequence and state diagrams. T/F

True

The data flow diagram must be augmented by min-spec that can serve as a guide the design of the software component that will implement the process. T/F

True

The behavior modeling is only used in the analysis of real-time systems. T/F

False

For purposes of behavior modeling an event occurs whenever

the system an actor exchange information.

For purposes of behavior modeling a state is any

observable mode of behavior

The state transition diagram

indicates system reactions to external events

False

Analysis patterns are discovered, they are not explicitly created. T/F

True

It is not possible to justify the time required for mobile app requirements analysis. T/F

False

Which is not one of the analysis activities that is used to create a complete analysis model?
