Play an AI-generated podcast conversation about this lesson

Which software development method involves interleaving specification, development, and validation?

Waterfall model
Agile methods
Integration and configuration
Incremental development (correct)

Why is there no universal process model that fits all software development types?

All software development requires identical resources
The software environment is always the same
