Which stakeholder must approve the business analysis approach to ensure that the business analysis approach is compatible with the other project activities?

The project sponsor provides funding and strategic direction but is not responsible for ensuring that business analysis activities are operationally integrated with other project activities.

The project manager owns overall project planning and is responsible for integrating all project activities into a cohesive plan, making them the appropriate stakeholder to review and approve the business analysis approach. Because business analysis activities must align with the project schedule, milestones, and management processes, the project manager must confirm compatibility before work begins. This is an operational integration concern, which falls under the project manager's authority rather than the sponsor's strategic oversight or the customer's requirements ownership.

The project customer defines needs and accepts deliverables but does not oversee the coordination and compatibility of internal project planning activities.

The change control board evaluates changes to established baselines such as scope, schedule, or cost, and is not involved in approving the initial business analysis approach.
