How o9 Works Understanding the Basics

BOM (Bill of Material)

Item A BOM Item B
  • Consumes one or more input items, produces one or more outputs
  • Defines yield: how much output per unit of input consumed
  • Has a lead time — the duration of the transformation
  • Runs at a specific location (plant or manufacturing node)
  • Can be chained to form multi-level Bills of Materials

A Transformation Process is the recipe that defines how items are made. It specifies which input items are consumed, which output items are produced, the yield per unit, the lead time, and the facility where it happens. In o9 this is known as the Bill of Materials (BOM) — and unlike traditional ERP, BOM and routing are unified into a single object. Processes can be chained: the output of one becomes the input of another, allowing o9 to resolve multi-level structures automatically when generating supply plans.
