In practice, iterations in the waterfall model are costly because of the need to revise documents and approvals.

What is a common consequence of this cost?

Design is always postponed until after implementation.

Requirements are continuously changed without control.

Requirements are prematurely frozen, even if not fully understood.

No documentation is produced to save time.

Correct Answer

Requirements are prematurely frozen, even if not fully understood.

Explanation

To avoid the cost of repeated document changes, organizations often freeze requirements early, which can lead to systems that do not fully meet user needs.
