A Project Manager lives with an open mind at all times. The two approaches to an unknown project is predictive and adaptive. When does the hybrid approach takes effect when operating as a Citizen Dev
Predictive and adaptive are extremes along a continuum. Very few projects are suitable for a 100% adaptive or 100% predictive approach and hence the vast majority of projects ARE hybrid.
Hybrid could come in different flavors including mixing lifecycle phases, picking tools and techniques from each toolkit or using a different approach for completing different work streams or deliverables.
