In situations where the project scope contains items that are well-defined and others that are complex and not fully understood, it is advisable to use a hybrid approach. The well-defined items can be managed using a predictive approach, which relies on a clear understanding of the scope, allowing for detailed planning and control. For the complex items, an agile approach is more suitable as it allows for iterative development, where the scope can be clarified and adjusted as more information is uncovered through progressive elaboration. This approach aligns with the PMBOK guide's emphasis on tailoring the project management processes to the needs of the project, which may include varying degrees of uncertainty and complexity12.
