Explanation
The In Jeopardy field on the Service Appointment is a checkbox that indicates whether a service appointment is at risk of late completion based on travel time and service duration calculations. Technicians can update this field using the Field Service Mobile App to alert dispatchers and managers of potential issues. Posting to the Service Appointment Chatter feed, changing the Status field on the Service Appointment, or adjusting the Scheduled End field on the Service Appointment would not indicate that a service appointment is in jeopardy, but would communicate other information such as comments, progress, or rescheduling.

Explanation
Global optimization is a process that reschedules all service appointments within a specified time frame based on predefined criteria such as travel time or priority[82]. Global optimization doesn't reschedule appointments that have rule violations because it assumes that those appointments are manually scheduled by dispatchers for valid reasons[83]. There are no service resources available with the required skill levels because updating the skills required on the most common work types has increased the complexity of jobs and reduced the pool of qualified resources[84]. The optimizer uses a scheduling policy different from what is used on the dispatch console would not explain why the jobs are still scheduled to resources that lack the appropriate skill level.
Scheduling policies are records that define the optimization criteria for scheduling service appointments such as minimizing travel time or maximizing resource utilization[85]. The territory of the resources was not included in the global optimization request would not explain why the jobs are still scheduled to resources that lack the appropriate skill level. Global optimization requests are records that specify which service territories and time frames should be optimized[86]. References:
