The project manager should use a hybrid model to combine predictive and adaptive life cycles. This approach allows for the initial planning and structure of the predictive approach while also incorporating the flexibility of the adaptive approach to respond to changes and new information. The hybrid approach is beneficial in scenarios where the project has clear phases but also requires adaptability to changing requirements and inputs from stakeholders.
