SYSE.16:0.1 - Terms and Distinctions
| Name in this pattern | What it denotes |
|---|---|
| project system-of-interest | A project-relative designation in plan or decision content. It names either an actual System or an intended-system designator. The designation, actual System identity, intended referent, and existence are separate claims. |
| use situation | A bounded actual situation in which the System participates, or a described possible-future situation in which the intended referent would participate. A scenario or diagram is a description of that situation. |
| containing whole | An actual System of which the selected System is a proper part under a stated relation, or a possible-future whole in a proposed proper-part claim. One System can belong to several relevant wholes under different relations. |
| suprasystem | Optional source wording for a containing whole. Use it only when the proper-part claim is stated. |
| other System in the use situation | An actual System, or intended referent, connected by a named non-part relation that matters to the decision. Examples include an interaction or transfer between named Systems; observation of one System by another; access granted by a provider System to a receiving System; supply of a named result from provider to receiver; receipt or use of that result; a commitment between named Agents; or a consequence relation. Each example names its own relation. |
| operating condition | A decision-relevant condition—for example, temperature, load, connectivity, price, an applicable regulation, or an available resource. A condition is a System only when it independently meets the System criteria. |
| functional organization | Selected transformation flows, interactions, and contributions, with the actual Systems that bear or participate in them. |
| constructive organization | Selected actual or proposed parts, bearers, modules, interfaces, and connections. Establish its parthood and connection relations independently of functional contribution. |
| engineering-use account | The episteme returned here: selected Systems, relations, structures, conditions, evidence, unsupported assumptions, and reopen conditions for one use decision. |
Relations commonly hidden by environment include parthood, interaction, ownership, location, authority, access, permission, service provision, use, and consequence. Name the relation that actually bears on the decision.
