The primary advantage of breaking a project into phases is that it enables teams to focus on critical themes and ease of governance. Phases provide a structure to manage complex projects by focusing on specific objectives or deliverables at each stage, facilitating better planning, monitoring, and control. This approach also makes it easier to align with governance requirements and tomake course corrections based on learnings from earlier phases. Options A, B, and C do not capture the strategic and governance benefits provided by phased approaches.
