The project manager should evaluate the project’s specific needs, resources, timelines, and risk tolerance to determine the most suitable project management approach. While the PMO is implementing adaptive tools, and the functional manager prefers predictive tools, the project manager’s responsibility is to assess the situation and decide on the approach that aligns best with the project’s goals and context. This decision should be based on a thorough understanding of both adaptive and predictive methodologies and their applicability to the project at hand. The project manager should consider the unique aspects of the project, such as its complexity, stakeholder expectations, and the degree of uncertainty, to make an informed decision.
