Core Concepts
What is TestAuto2? — High-level overview of the solution’s purpose, capabilities, and target users. RTM Domain Model — How entity types, relationships, and cardinality constraints structure your traceability matrix. Workflow Lifecycle — Document state transitions, review gates, and approval workflows for risk and requirements documents. Document Types and Modules — The seven document types in TestAuto2 and how they organize HARA, FMEA, and control plan analyses. System Element Hierarchy — How system, subsystem, component, and subcomponent elements structure your system decomposition.Safety Standards & Methodologies
ISO 26262 Functional Safety — How TestAuto2 implements ISO 26262 V-cycle phases, HARA workflow, safety goals, and ASIL classification. ISO 14971 Risk Management — Risk assessment, control planning, and residual risk evaluation for medical device safety. AIAG-VDA FMEA Methodology — The ten-step FMEA process, severity/occurrence/detection scales, and action priority calculation. IATF 16949 and APQP — Automotive Quality Management System requirements and Advanced Product Quality Planning phases aligned with TestAuto2. ISO 21448 SOTIF — Safety of the Intended Functionality for systems without systematic failures.Risk Analysis & Classification
ASIL Classification System — Automotive Safety Integrity Level calculation from Severity, Exposure, and Controllability (S/E/C). Safety Goal Derivation — How HARA hazards flow to safety goals, ASIL targets, and functional requirements. Action Priority Methodology — How Severity × Occurrence × Detection (S×O×D) determines action priority in FMEA. SC/CC Special Characteristics — Safety and Controllability characteristics that require enhanced control in manufacturing. Risk Control Types — Design controls, production controls, verification controls, and monitoring controls.Analysis & Verification Models
Verification vs Validation — Distinction between verification (does the system meet requirements?) and validation (does it meet customer needs?).Key Relationships
