In a product development project, the project manager is constantly receiving complaints from stakeholders about functionalities being delivered, but not required by the business departments. The project sponsor wants to know if the project resources are being used effectively. What should the project manager have done to avoid delivering work that is not adding value to the business? Ask the stakeholders to document their complaints in change requests. Document the stakeholders' needs, review them during the retrospective, and create improvement plans. Define a product scope and ask the stakeholders to not deviate from it. Encourage the product owner to meet with the stakeholders and create a product backlog based on their needs
