The Superseded Parts Data Checklist
For catalog teams, product data managers, and operations leads responsible for spare-parts catalogs with discontinued, superseded, or legacy part numbers.
Summary
Supersession data lives in price-list diffs, ERP notes, product specialists' memories, and shared-drive spreadsheets — everywhere except where it would actually prevent a wrong-part order or a dead-end search. This checklist gives catalog and operations teams a structured way to audit their supersession records: a status vocabulary so every part's lifecycle state is unambiguous, chain-integrity checks that catch broken or circular links, quantity and interchangeability checks for splits, merges and pack-size changes, minimum fields for a trustworthy supersession record, and a scoring worksheet to measure where the catalog stands and where to improve first. The page you are reading is only the summary; the PDF contains the full checklist, the scoring worksheet, and worked examples.
What's inside
- A status vocabulary that distinguishes active, discontinued, superseded, pending review, last-time buy, NLA and end-of-life — with when to use each.
- Chain-integrity checks: detect broken chains (successor is also discontinued), cycles, depth anomalies, and chains that resolve to an inactive terminal part.
- Quantity and interchangeability checks: verify quantity ratios on splits and merges, flag pack-size changes without recorded ratios, and separate supersession (REPLACED_BY) from equivalence (EQUIVALENT_TO).
- Minimum fields for a trustworthy supersession record: old ID, new ID, direction, effective date, quantity ratio, source, confidence, created-by.
- A scoring worksheet: measure supersession completeness, chain integrity, source coverage and quantity-ratio coverage as percentages, set targets, and prioritize fixes by business impact.
