Service Resources are records that represent the people or equipment that perform field service

tasks[53]. Permission Set Licenses are licenses that grant users access to specific features such as

Field Service Dispatcher Console or Field Service Mobile App[54]. Creating one service resource and

assigning the relevant permission set license would allow an employee at Universal Containers to

perform both dispatcher and technician roles using one record and one license. Creating two skills

records and assigning them to service resources record would not affect their roles or access to

features. Skills are records that define specific abilities or qualifications that service resources

have[55]. Creating two service resources and assigning them to the employee would create duplicate

records and require two licenses for one employee. Creating one service resource and assigning the

technician and dispatcher role would not work because roles are not fields on the service resource

object.
