Explanation
Match Boolean is an optimization criterion that prioritizes matching service appointments with resources based on boolean fields such as certifications or preferences[139]. Using Match Boolean in the Scheduling Policy would allow Universal Containers to ensure that Service Appointments are only assigned to Active Resources by creating a boolean field on the service resource object such as Active Resource and setting it to true or false depending on their status. Match Fields is an optimization criterion that prioritizes matching service appointments with resources based on fields such as skills or territories[140]. Preferred Resources is an optimization criterion that prioritizes assigning service appointments to resources who have previously completed similar work orders or who are preferred by customers[141]. Required Resources is an optimization criterion that prioritizes assigning service appointments to resources who are explicitly required by customers or dispatchers[142]. References:

Explanation
Earliest Start Permitted is a field on the Service Appointment object that defines the earliest date and time that a service appointment can start[222]. Due Date is a field on the Service Appointment object that defines the latest date and time that a service appointment must be completed by[223]. Using Earliest Start Permitted and Due Date fields on Service Appointments would help ensure that they are completed within the agreed upon Service Level Agreement (SLA) with Universal Containers' customers by setting the boundaries for when a service appointment can start and finish according to the SLA terms[224]. Actual Start and Actual End are fields on the Service Appointment object that capture the actual date and time that a service appointment started and ended[225]. Using Actual Start and Actual End fields on Service Appointments would not help ensure that they are completed within the agreed upon SLA with Universal Containers' customers because they are recorded after the service appointment is performed and do not enforce any SLA terms. Arrival Window Start and Arrival Window End are fields on the Service Appointment object that define the expected date and time range that a resource will arrive at a service appointment[226]. Using Arrival Window Start and Arrival Window End fields on Service Appointments would not help ensure that they are completed within the agreed upon SLA with Universal Containers' customers because they only indicate when a resource will arrive and do not enforce any SLA terms. Scheduled Start and Scheduled End are fields on the Service Appointment object that define the planned date and time range that a service appointment will take place[227]. Using Scheduled Start and Scheduled End fields on Service Appointments would not help ensure that they are completed within the agreed upon SLA with Universal Containers' customers because they only indicate when a service appointment is scheduled and do not enforce any SLA terms.

Explanation
Products required and skill requirements are two fields that should be included when creating a work order to increase first-time fix rates. Products required are used to specify the products that are needed for the work order, and skill requirements are used to specify the level of expertise that is needed for the work order. By including these fields, the system can ensure that the technician has the right parts and skills to complete the work order.
