Estimating Software, Labor and Part Categories, and Line Item Construction
What this domain tests
Software and line construction. The exam tests the structure of a line in CCC ONE, Mitchell or Audatex-type platforms: operation code, description, hours, rate, part type, quantity, price, source and warranty, and how labor and part categories are assigned.
Core rules
- Identify the vehicle by VIN and trim so the labor database returns the right times. Wrong trim or powertrain produces wrong hours and wrong part numbers.
- Labor categories are distinct: body, paint/refinish, frame/structural, mechanical, electrical/diagnostic, sublet. Calibration is usually its own line or sublet.
- Part types are explicit fields: OEM new, OEM remanufactured, OEM recycled, aftermarket, reconditioned. Changing the source later without changing the part type is a common audit failure.
- Use coded operations wherever they exist; freehand lines lose the audit trail and invite challenge.
- Handle overlap deliberately: if operation B includes part of operation A, use the overlap function rather than deleting hours arbitrarily.
- Materials are a separate line, typically tied to refinish hours or a stated mix.
Worked example
A door shell replacement on a vehicle with a mirror-mounted camera. Lines: door shell; R&R door trim panel and belt molding; R&I glass and regulator; transfer of the wiring harness; refinish door exterior, jambs and a blend into the front door and quarter; pre- and post-repair scan; camera calibration. Reasoning: the door shell replace operation does not include glass, trim, harness transfer or calibration, so each is added on its own.
Traps
Manually typed hours that overwrite the database time; forgetting the blend and jamb refinish; leaving the part type on OEM after sourcing recycled; missing the materials line; double-billing an operation already inside a larger one; and omitting calibration after a mirror- or windshield-mounted camera is disturbed.
