Explanation
= According to the Agile Practice Guide, changes are inevitable and welcome in agile projects, as they provide opportunities to deliver more value to the customer1. However, changes should be evaluated and prioritized by the customer or the product owner, who represents the customer's voice2. The project manager should facilitate the change management process and ensure that the changes are aligned with the project vision and goals3. Therefore, the project manager should continue the iteration and review the change with the customer, who can decide whether to accept, reject, or defer the change. This is also consistent with the agile principle of delivering working software frequently and satisfying the customer through early and continuous delivery of valuable software4. References:
