In an agile project, the scope is not fully defined at the beginning. Instead, it evolves as the project progresses. This approach allows for flexibility and adaptability to changes, which is a key characteristic of agile methodologies. Therefore, the project manager should start executing the project, understanding that the scope will be defined and redefined throughout the project.
