In a large organization, with projects of different types and sizes, what kind of approach or method would be best to use?

Predictive alone is too rigid for projects with high uncertainty or rapidly changing requirements, limiting the organization's ability to respond effectively.

Adaptive alone may not suit all projects - particularly those with fixed regulatory requirements or well-understood scope - making it insufficient as the sole method.

No single approach fits all project types. Predictive methods work well for projects with well-defined scope and low uncertainty, while adaptive or agile methods suit projects with evolving requirements. A large organization spanning multiple domains should select and tailor the approach based on each project's characteristics, risk, and complexity, which is exactly what a hybrid or mixed approach enables.

Agile is a subset of adaptive approaches and shares the same limitation as choice B - it does not address the needs of all project types in a large organization.
