Explanation
Work Types are templates that define the duration, skills, and products required for a work order or work order line item. By creating Work Types and Skill Requirements for Install, Break-fix, and Inspections, Universal Containers can standardize creation of Work Orders with the correct skills and estimated time to completion.
Work Order Record Types for Break-fix, Install, and Inspection would allow creating different page layouts and picklist values for different types of work orders, but not define skills and duration. Work Type Line Items for Install, Break-fix, and Inspections would allow creating templates for work order line items, but not work orders. Work Order custom fields to define Install, Break-fix, and Inspections would allow capturing additional information for different types of work orders, but not define skills and duration. References:

Explanation
Assets are used to track the customer's install base, such as products or equipment that require service. Work orders are used to track the work that needs to be done on assets. By relating work orders to assets, the system can track the work history and status of each asset.

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
Service Territories are used to group resources and service appointments based on geographic areas or other criteria. The recommended limit for service appointments per territory per day is 500 for optimal performance and user experience.

Explanation
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 card in 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].
