SYSE.6:8 - Common Failures and Repairs

FailureSymptomRepair
Local choices as architectureInterfaces, modules, suppliers, and software partitions accumulate without a joint decision.Select the project-shaping structures and make one bounded C.32.PAD decision relation with explicit receiving Work.
Architecture as everything importantThe decision includes every design detail and unresolved issue.Keep only selected structures coordinating several choices or protected characteristics; leave named refinement open.
Hard-to-change definitionCostly change alone makes an item architectural.Name the selected structure, current alternatives, consequences, and decision use; difficulty is one possible characteristic.
Quality catalogueGeneric qualities are scored without bearers, conditions, Scales, or protected losses.Create a small C.32.ACS criteria set for the current decision and preserve non-equivalent readings.
Metric as selectorA dashboard or eval result chooses the architecture automatically.Interpret the reading under its subject and parity frame, then use the direct comparison and decision patterns.
Modularity as universal goodMore modules, fewer connections, an open standard, or one supporting System is assumed better.Compare decision-relevant consequences—for example, function bearing, coupling, cohesion, substitution, integration, evidence, cost, supply, or change—under the stated use.
Candidate without realizationA plausible structure lacks a needed realization dependency—for example, a transformer System, capability, interface realization, integration relation, or evidence return.Record a bounded residual or return the unsupported branch to SYSE.3; do not hide it in an architecture label.
Organization mirroring shortcutCurrent teams or communication links are copied into technical architecture by analogy.Use C.32.CONWAY only for a stated influence or correspondence question; keep organization and engineered-System structures distinct.
Record as decisionAn ADR or diagram exists, but selected option, relation, losses, and effectivity are unclear.Recover the decision relation first; publish it afterward through the description and publication patterns.
Decision as actual structurePossible-future selected content is reported as installed architecture.Inspect the actual Systems and obtaining relations after Work; keep divergence and evidence separate.
Frozen architectureLater integration or operation contradicts the basis, but the old record remains authoritative.Apply the named reopen condition and supersede the smallest affected decision.
Whole-project exceptionAny local refinement or residual requires centralized architecture approval.Preserve the fixed/open boundary and escalate only changes that cross a declared structure, guardrail, or affected decision.
