volume_mute

True or False: The waterfall, incremental, and reuse-oriented process models are mutually exclusive and cannot be used together in the same project.

Combining Process Models in a Large System Different subsystems may use different development approaches Large Enterprise System Well-Understood Business Logic Waterfall Model User Interface Evolving Requirements Incremental Development Shared Services COTS / APIs Reuse-Oriented Development Real systems often combine multiple software process models

Correct Answer

False

Explanation

These models are not mutually exclusive and are often used together, especially for large systems development. Parts of a system that are well understood can be specified and developed using a waterfall-based process, while parts difficult to specify in advance should be developed using an incremental approach.
