Crew Management is a feature that allows creating and managing crews of multiple service
resources who share the same service appointments[163]. The Preferred Resource service objective
is ignored for active Crew Members because it only applies to individual resources and not
crews[164]. Capacity-based scheduling is not supported for Service Crews because crews do not have
capacity limits and can be assigned unlimited service appointments[165]. A service resource can be a
member of multiple crews and can switch between them depending on their availability and
skills[166]. Salesforce Field Service does not consider the Recommended Crew Size when assigning
appointments because it only considers the Required Crew Size which indicates the minimum
number
of
crew
members
needed
for
a
service
appointment[167].
