Product, Product Line, and Product Tier

A Product is an activity or resource one Economic System produces and another uses in producing its own product. A Product Line is a revenue-producing product of a firm, described with reference to the Enterprise Barcode. A Product Tier is the set of three loci — a Constituent Resource Locus, a Final Resource Locus, and a Work Group Locus — that together describe one instance of a product’s usage.

The three sit at different levels of the same idea. Product is the broadest: any output one system hands to another. Product Line narrows that to the specific, revenue-generating version an enterprise actually sells — a company with several genuinely distinct offerings has several product lines, each getting its own Enterprise Barcode. Product Tier is narrower still: it’s not the product itself, but the barcode machinery that traces where a given product tier’s resource ends up — which is why the Customer Field and Customer of Customer Field each contain two of them, tracing usage one level deeper each time.

One product line doesn’t have to be a company’s only one, or even its main one. An Auxiliary Product Line is a product line not represented by the firm’s Summary Barcode — a minority revenue line, or one that got aggregated away when the Summary Barcode was chosen. The Product Line Marker flags exactly this: when a department’s activity relates to a customer’s auxiliary line rather than their main one, the marker records “Auxiliary” instead of “Main.” The book’s own example is a university buying lab supplies — the supplies serve the university’s main function of education, but also its auxiliary function as a research institution, and the barcode needs the marker to tell those two uses apart.
