Explanation:
Answer 2
Answer:

Final answer:

The Waterfall model of software development doesn't allow for revisiting previous stages, in contrast to the Agile model which allows for continual revisiting and modification.

Explanation:

The Waterfall model does not allow you to revisit previous stages of the software life cycle; the Agile model does allow previous stages to be revisited. These are both models used in software development. The Waterfall model is a linear approach, where each phase must be completed before moving on to the next one, meaning once a phase has been completed, it is not revisited. On the other hand, the Agile model is iterative, allowing for constant revisions and adaptation throughout development, hence making it possible to revisit previous stages.
