# Assembling

*/Activities/Assembling*

GS1 EPCIS business step: assemble components. Sets disposition to InProgress via a TransformationEvent. Typically occurs at a factory.

## Overview

Assembling merges discrete components into a newly identifiable product, triggering a formal transformation event that consumes input serial numbers and generates a new output identity. This physical process on the factory floor forces operators to scan or manually log every batch, lot, and serialized part that enters the final build. The resulting data structure forms the traceability tree required for compliance, warranty verification, and targeted recalls.

Reconciling the physical assembly with the digital Bill of Materials generates continuous administrative overhead. Factory workers repeatedly stop production to correct mismatched lot codes, log approved part substitutions, and fix data gaps caused by missed barcode scans. Broken data links in the transformation record severely limit a manufacturer's ability to isolate affected units when a defective component enters the supply chain.

This step provides immediate utility for spatial reasoning agents and headless event-logging services. Vision models observe the workstation, identify individual components during assembly, and automatically structure the activity into a standard tracking event without manual scanning. This shift completely removes data entry from the assembly line while ensuring an uninterrupted digital lineage for the finished good.
