Understanding Terminal Case Marker (TCM)

The TCM sits in the Work Group Field and is derived by examining the object of the First Work Group Locus and determining that resource’s role in the customer’s operations, using a table of seven possible work-group-object types, each mapped to whether the resulting work group is terminal (sitting at the Central Department Cycle) and why. Its full set of values is Product, Money, ItP(1), ItP(2), Subject, ItS, Byproduct, DivT, DivNT, and DivM: Product and Money mark true terminal cases (the work group acts directly on the customer’s product, or on money received as compensation); ItP(1), Subject, and ItS mark non-terminal cases where the object is a constituent of the customer’s product or a subject resource used in the customer’s operations; ItP(2) is non-terminal because the activity is in Phase 2 even though the object is a constituent of the product; Byproduct terminates by convention since byproducts are inherently non-functional; and DivT, DivNT, and DivM handle aggregated barcodes, with DivM treated specially since the department can’t be copied from a single terminal work group. Whenever a work group is found non-terminal, coding proceeds to a second product tier, structurally identical to the first (another CRL, FRL, and WG), now describing the object of the first work group rather than the object of the Enterprise Locus — a step upward through Work Group Levels; in the rare cases needing more than two tiers, only the first two are ever recorded in the barcode.
