SYSE.14:1 - Problem Frame
One controller change can alter actual Systems, interfaces, and behaviour; change needed manufacturing or service Work; and invalidate descriptions or supporting evidence. A release for realization may precede implementation under the applicable release rule. A release to service normally concerns an actual System in an observed configuration after implementation. Treating both as one generic approval loses the decision subject and its evidence.
Workflow tools can coordinate records and checks, but their status labels are not the engineering ontology. Approved can denote, for example, acceptance for analysis, technical selection, permission, release for build, a gate result, an installed-state claim, or acceptance for use. Those results have different Agents, authority, evidence, subjects, and consequences.
