Hybrid means a blend of delivery approaches. Here are the ways where one could claim to follow a hybrid life cycle: 
- 
Some variant on Water-Scrum-Fall, Scrum-Fall, or Water-Scrum. 
 
- 
A project where distinct work packages lend themselves to either an adaptive or a predictive life cycle and need not be integrated and verified as a coherent whole. An example of this might be the training work packages supporting a technology application. 
 
 The former could be developed in a traditional manner whereas the latter could be done in an agile manner. This still feels a little like Scrum-Fall, but so be it.
