An organization is starting a multi-phase project. Strict regulations require some phases to be fully planned upfront, while other phases allow flexibility and experimentation. The sponsor wants to follow the planned objectives but also incorporate new information and changes as the project progresses. Which project management approach should be chosen?

A hybrid approach is best because it combines elements of both predictive (waterfall) and adaptive (agile) methodologies. This allows for upfront, detailed planning for phases with strict regulatory requirements (predictive) while enabling flexibility, experimentation, and incorporation of new information for other phases (adaptive). Incremental focuses on delivering functional components in iterations but doesn't explicitly address the need for upfront, detailed planning for regulated phases. Agile is primarily adaptive and would not suit phases requiring full upfront planning. Phased describes a project structure but doesn't specify the management approach within those phases; a phased approach could be predictive, adaptive, or hybrid.
