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:
