A project manager is managing a project which is approaching the end of the execution phase. A high-level stakeholder informs the project manager that a very important requirement was not included in the scope of the project, and that without that requirement the project will deliver no value. What is the first thing the project manager should do? Inform the stakeholder that it is impossible to add new requirements to an approved project scope. Inform the project sponsor about the situation and request assistance. Include the requirement into the project and schedule it as soon as possible. Evaluate the impact that the inclusion of this new requirement will have on project performance
