What best describes a sequential development model in software development?

Testing occurs before development activities start.

There is no overlap between phases. (correct)

Activities are completed concurrently.

Phases can begin before the previous phase is completed.

In the context of software development, what characterizes a waterfall model?

Testing occurs only after all development activities are completed. (correct)

Phases are revisited iteratively.

Testing occurs simultaneously with development.

Activities are completed concurrently.

Waterfall model

Incremental development model
