1) If the scope has only been defined at a high level then the next step would be to fully define the scope with a product and work breakdown structure. The PBS would define all the deliverables that the project has to produce, in a structured way. The WBS would define all the work required to produce those products. For examples a new house would have foundations, wall and roof. The Work would be laying the foundations, building the walls. By checking these deliverable sheet stakeholder expectations we can be confident in the scope.
