SYSE.4:8 - Common Anti-Patterns and How to Avoid Them

Anti-patternWorking symptomRepair
Test chosen after commitmentThe implementation is treated as settled before anyone asks what result could change the decision.Name the load-bearing claim and decision question, recover usable evidence, and select further inquiry when its attainable contribution justifies the burden.
Component pass as outside benefitA pump, deployed software System, or material passes a bounded test and the containing System’s use claim is declared proven.Keep component, containing-System, and outside-effect claims separate and obtain evidence for the claim the decision actually uses.
Assurance plan as evidencePlanned checks, booked facilities, or named results are treated as if Work and results already exist.Keep the DPF plan, A.15.2 WorkPlan, actual Work, result, evidence use, and account separate.
Model confidence as validityFamiliarity, model history, or a confidence score replaces applicability, uncertainty, extrapolation, and physical evidence.Recover the model-use claim and its limits; obtain another evidence line when the decision requires it.
Digital twin or pipeline as assuranceAutomation and traceability are treated as a complete assurance Method.Name the model, check, observation, result, evidence use, and missing specialist decision maintained by the arrangement.
Evidence pileReports, dashboards, tests, and certificates are accumulated without a target claim or decision question.Retain only the descriptive A.10 paths needed by the current claim and bounded use; keep other results available without claiming relevance.
Stale configuration reuseA result from another version, calibration, environment, load, or observation window is reused unchanged.Recheck applicability and currentness; narrow the use or plan a challenge for the current configuration.
Acceptance or release by testA technical result is treated as acceptance, permission, certification, gate passage, or release.Apply the result only to the decision and criteria that can use it; record only the engineering claim it supports here.
Terminal assurance stageEvidence is collected once at the end and cannot revise project focus, concepts, architecture, or realization.Use SYSE.4 whenever a claim becomes load-bearing, and reassess only the earlier answer changed by each result.
