In incremental development, the fundamental activities of specification, development, and validation are not strictly separated.

How are these activities organized in incremental development?

They are completely replaced by maintenance activities.

They are strictly sequential with no overlap.

They are performed only once at the start of the project.

They are interleaved, with rapid feedback between them.

They are interleaved, with rapid feedback between them.

Incremental development cycles through specification, development, and validation for each increment, allowing frequent feedback and adjustment.
