Explanation
According to the Agile Practice Guide, one of the agile principles is to satisfy the customer through early and continuous delivery of valuable products. To achieve this, the project manager should involve the customer and other stakeholders in frequent feedback loops, such as sprint review sessions, where the team demonstrates the working product increment and collects feedback for improvement. This way, the project manager can ensure that the product features align with the customer's expectations and needs, and avoid product rejection or rework. Creating dedicated sprints to fix the rejected features, asking for a new product owner, or sharing the product backlog in advance are not effective ways to mitigate the product rejection, as they do not address the root cause of the misalignment between the team and the customer.
