Enumeration Categories
TestAuto2 organizes enumerations into three primary categories based on their usage context:
Safety Assessment Enumerations
HARA Severity (S0-S3) — Severity levels from negligible (S0) to catastrophic (S3) for hazard assessment.
HARA Exposure (E0-E4) — Exposure probability levels from extremely low (E0) to high (E4) reflecting likelihood of hazard occurrence.
HARA Controllability (C0-C3) — Controllability levels from not controllable (C0) to easily controllable (C3) for risk mitigation assessment.
ASIL Classification (QM, A-D) — Automotive Safety Integrity Levels assigned based on severity-exposure-controllability combinations, ranging from QM (no safety requirement) to ASIL D (highest).
Harm Severity — Severity classification for potential harms identified during hazard analysis.
Risk Probability — Probability levels for risk occurrence assessment in risk records.
Risk Level — Overall risk classification combining probability and severity dimensions.
FMEA Analysis Enumerations
FMEA Severity (1-10) — Ten-point severity scale for failure mode effects on product function or safety (1 = negligible, 10 = catastrophic).
FMEA Occurrence (0-10) — Ten-point occurrence scale for failure mode frequency (0 = zero, 10 = very high).
FMEA Detection (0-10) — Ten-point detection scale for control effectiveness (0 = certain detection, 10 = zero detection).
Action Priority (H/M/L) — Priority levels (High/Medium/Low) derived from severity, occurrence, and detection ratings to sequence corrective actions.
PFMEA Occurrence — Process-specific occurrence scale for manufacturing failure modes.
PFMEA Detection — Process-specific detection scale for control plan effectiveness.
System Configuration Enumerations
System Element Status — Status tracking for system architecture elements (e.g., planned, active, deprecated).
Design Requirement Subtype — Subtypes distinguishing design requirement categories (e.g., functional, performance, safety, interface).
Control Type — Classification of risk controls as preventive (reduces occurrence) or detective (enables detection).
Document Type — Work item types for document organization and traceability mapping.

Common Usage Patterns
During HARA Workflow: Assign severity, exposure, and controllability values to hazards. The system automatically derives ASIL from these three dimensions.
During FMEA Analysis: Score failure modes using severity (1–10), occurrence (0–10), and detection (0–10). Risksheet formulas calculate Action Priority automatically based on configured thresholds.
During Risk Control Planning: Classify controls as preventive (reduces occurrence) or detective (enables detection) using the Control Type enumeration.
During Requirements Definition: Subtype design requirements to distinguish functional, performance, safety, and interface categories for traceability and verification planning.
