What is the best practice when approaching iterative development?

Wait until the end of the project to gather feedback from stakeholders.
Include complete requirements, design, coding integration, testing in each iteration. (correct)
Deliver incomplete work to stakeholders for feedback.
Ignore feedback from stakeholders.

In iterative process models, how are requirements typically prioritized?

Based on the customer's ranking of important features. (correct)
Based on the team's preference.
By the order in which they were received.
By the complexity of each requirement.

Why is it important to treat each iteration as a 'closed-end mini-project'?

To maintain a structured approach where each iteration is self-contained. (correct)
To keep stakeholders uninformed about progress.
To discourage collaboration within the team.
To ensure there is no flexibility in project execution.
