A project manager is leading a global project with resources spread out in different locations. The stakeholders have different interpretations of the requirements. The project manager is concerned about scope . Which action should the project manager take to control the scope? Ensure that all key stakeholders agree to the project deliverables and there will be no need for changes. Accept only those changes that are approved by the change control board (CCB) prior to being implemented. Accept only those changes to requirements that provide additional value to the project. Reject all changes that will increase the budget or increase the time line of the project
