partslista

A partslista (parts list) is a formal document that enumerates all components, raw materials, subassemblies, and spare parts required to manufacture, assemble, or repair a product. It typically includes fields such as part number, description, quantity, unit of measure, and reference designators, and may also record supplier, unit cost, lead time, and material type. In many contexts, a partslista is used interchangeably with a bill of materials, though BOM is the broader term in engineering and manufacturing.

The primary purpose of a partslista is to support procurement, inventory management, production planning, maintenance, and cost estimation. It provides traceability from finished products to individual components and helps manage substitutions, revisions, and compatibility across versions.

Structure and scope: Common fields include part number, description, quantity, unit, reference designator, supplier, cost, lead time, status, and revision. A partslista can be flat or multi-level, with assemblies and subassemblies shown in parent-child relationships. In electronics, a dedicated BOM-like list often captures circuit references; in mechanical contexts, it emphasizes fasteners, standard components, and modules.

Formats and tools: Partslistas are stored as spreadsheets, databases, or within ERP (enterprise resource planning) and PLM (product lifecycle management) systems. Digital lists enable version control, change management, and integration with purchasing, production, and maintenance workflows.

Lifecycle and governance: They are created during design and updated through engineering change processes. Revisions are tracked, approved, and archived to maintain traceability; lot-level or serial-number associations may be recorded for manufactured items.

Usage across industries: Widely used in electronics, automotive, machinery, and construction; the exact content and structure vary by industry and company standards. See also: bill of materials, ERP, PLM, change management.
