In inventory management, spare-part FRU tracking primarily involves which practice?

• A. Recording serials and locations of field-replaceable units to support traceability.
• B. Color-coding spare parts by supplier.
• C. Estimating spare parts' market price.
• D. Archiving retired FRUs for future use.

Answer: (A)

Traceability is the primary idea here: you must know each field-replaceable unit’s serial number and current location to follow its lifecycle. Recording serial numbers and where each FRU is located creates a precise trail showing its origin, deployment, and service events, which supports correct part installation, warranty claims, recalls, and quick retrieval during maintenance. Visual organization like color-coding by supplier helps storage readability but doesn’t provide the exact unit-by-unit history needed for traceability. Estimating market price focuses on cost, not tracking, and archiving retired FRUs may preserve records but doesn’t offer active, real-time visibility of in-use parts.
