SYSE.3:4.3 - Find the first unsupported answer
Use the A.1.STM long mantra to keep the architecture result, intended outside use, and builder dependencies in
attention. Read the logical dependency backward and find the first unsupported answer that prevents one credible
next realization action. First means logically first for this dependency, not earliest in a calendar or
prescribed process.
Use these six working questions to classify the first gap:
| Working question | Result or next practice that resolves the gap |
|---|---|
| Which existing System could perform the intended Work? | Name a candidate transformer System and role condition, or use the System-recognition or specialist-search Method that can supply one. |
| Can that System perform the Work under the required conditions? | State the missing A.2.2 capability claim, threshold, envelope, qualification, or currentness result. |
| Which Method and means make the intended result plausible? | Name the Method question and the missing resource, tool, access condition, or platform contribution. |
| Can the selected structures be constituted and connected? | Name the missing interface, integration, configuration, placement, or production-feasibility result. |
| Which prior change makes the transformer or means available? | Open one recursive realization branch for that System, capability, Method, tool, or platform contribution. |
| Does the proposed architecture still have an admissible realization? | If no branch remains, name the C.32 candidate, architecture decision, or linked use-and-system concept that the failure requires the practitioner to reopen. |
Record the first gap even when later gaps are already suspected. Use it to choose the next action.
