C.31.ASAP:4.4 - Scale variables
Typical architecture scale variables include:
| Scale variable | Reading |
|---|---|
N_units | repeated units or instances |
N_scopeCount | aggregation scopes, coarse-graining scopes, or typed LCA control scopes |
N_sites | deployments, sites, markets, or jurisdictions |
N_interfaceTypes | distinct interface grammar variants |
N_requiredTransformationKinds | distinct transformation kinds in the selected functional-structure view |
N_flowRelationKinds | flow-relation or crossing variants in the selected flow-structure view |
N_moduleTypes | module type library size |
N_workRepetitions | delivery, operation, or test repetitions |
N_supplierOrVendorClasses | substitutability or vendor class dimension |
N_regulatoryInstances | approval, safety, or certification repeats |
freedomOfAction | allowed design, search, or control variation |
The scale variable is not enough by name. The claim being made also needs a scale window, expected stable or improving structure, exception-growth risk, and source-return condition.
