Collection evaluation is the method by which Configuration Manager (Config Mgr) takes the collection rules you have defined and updates collection membership based on these rules.
Incremental evaluation uses a collection evaluation graph to evaluate and update dependent collections if an update to the incremental collection membership changes.
Since Config Mgr 2012, all the collections should be dependent on All Systems or All Users and Groups directly or indirectly.
This is the highest priority collection evaluation.
