Lightning Components are reusable units of user interface that can be customized and embedded in different pages or apps[180]. Work Order Line Items are records that track specific tasks or products related to a work order[181]. Creating a custom Lightning Component that displays Work Order progress and deploying it to Technicians through the Salesforce Field Service mobile app would allow Universal Containers' Technicians to view work progress through the Work Order Line Item card in the Salesforce Field Service mobile app by creating a component that shows the status or completion percentage of work order line items and adding it to the work order line item card layout in the mobile app settings[182]. Creating a custom Visualforce page and adding an external link in the Salesforce Field Service mobile app to view the page in the mobile browser would not allow Technicians to view work progress through the Work Order Line Item cardin the Salesforce Field Service mobile app. Visualforce pages are web pages that can display custom user interface using HTML, CSS, JavaScript, and Apex[183]. Creating a Report Chart that summarizes Work Order Line Items and adding a link to the Service Appointment layout would not allow Technicians to view work progress through the Work Order Line Item card in the Salesforce Field Service mobile app. Report Charts are visual representations of report data that can be added to different pages or layouts[184]. Adding the Work Order Line Items related list to the Work Order page layout and assigning the layout to the Technician's profile would not allow Technicians to view work progress through the Work Order Line Item card in the Salesforce Field Service mobile app. Related lists are lists of records that are directly related to another record and can be added to different page layouts[185].

Updating the Resource as not available allows marking a resource as unavailable for a specific time period due to sickness, vacation, or other reasons[27. Selecting the affected Service Appointments and pressing
"Schedule" allows rescheduling multiple service appointments at once based on predefined criteria such as travel time or priority[28. Dragging and dropping the Service Appointments to other available Resources and running Optimization would reschedule service appointments manually and then run an optimization process that could override the manual changes[29. Asking the Customer Service Rep to call the customers and manually re-schedule for another day would not use the scheduling features of Field Service and could result in customer dissatisfactionor missed service level agreements. Changing the Scheduling Policy to "High Intensity" and activating the Background Optimization process would change the optimization criteria for all service appointments and run an optimization process in the backgroundthat could take a long time to complete[30.

User Territories are records that associate users with service territories for sharing purposes[90]. Creating a new user territory associated with the Service Territory and dispatcher would allow giving access to all relevant Midwest records by linking them with their corresponding service territory[91]. Configuring and running the User Territory Sharing Jobin Field Service Settings would allow updating sharing rules based on user territories automatically at regular intervals such as daily or weekly[92]. Assigning a new user territory and adding each of the assigned service resources would not give access to all relevant Midwest records

A Service Appointment with a single Work Order with Work Order Line Items for each Asset allows servicing multiple Assets at a customer site during a single visit with minimal impact for the customer and consolidated work for the Technician[28. Creating and scheduling independent Work Orders for each Asset, each with a Service Appointment, would create unnecessary complexity and duplication. Creating designated Time Slots to ensure appropriate time is held to accommodate these types of visits would not address the requirement of servicing multiple Assets. Creating a single Work Order with Work Order Line Items for each Asset, each with a Service Appointment, would create redundant service appointments for the same visit.
