Explanation
These three considerations should be taken into account when implementing service level agreements for work orders, as they affect how milestones are created and applied to work orders. References:

Explanation
Work types can be used to assign associated articles to work orders, which can be accessed offline by technicians using the Field Service Mobile App. The Salesforce Mobile App does not have deep linking to the Field Service Mobile App. Creating a custom Mobile App that syncs articles based on service appointment assignments is not necessary and would require additional development and maintenance. Writing a workflow that associates articles to work orders based on a picklist on the work order is not recommended and would not ensure offline access.

Explanation
Operating Hours define when service resources are available for work and when customers can book appointments. The Time Slots for Appointment Booking setting determines how operating hours are divided into time slots that can be assigned to service appointments. The Maintenance Plan for the Account or the Due Date of the Service Appointment do not affect operating hours, but are used to generate and schedule recurring work orders.

Explanation
Field Service Lightning Admin Permissions are required to set up new territories, define new schedule policies, and control settings on the Gantt chart. These permissions allow users to access and modify field service settings and objects.

Explanation
This option should be recommended to meet this requirement, as it allows creating a service resource that represents a group of technicians who work together on the same service appointment. References:
