Safety-critical system

Safety-critical system refers to systems whose failure could result in injury, death, or environmental damage. Standards like ISO 26262 and IEC 61508 provide the framework for risk-adjusted design and management of these systems. The core concept is that the severity of the consequence, rather than just the probability of failure, dictates the necessary level of rigor in design and testing. In enterprise risk management, these systems require a lifecycle approach—from hazard analysis and risk assessment (HARA) to verification and validation (V&V)—to ensure compliance with safety integrity levels (SIL).

Practical application involves four key steps: Hazard Identification, Risk Assessment (using FMEA or FTA), Risk Mitigation (designing redundancy or fail-safe mechanisms), and Verification & Validation. For example, a European automotive supplier implemented ISO 26262 standards, achieving a 40% improvement in fault detection rates and a 25% reduction in customer complaints within 18 months. This-led to a significant increase in tier-1 supplier opportunities. Companies must also be closely monitored through continuous performance-based metrics to ensure ongoing compliance and reliability.

Taiwan enterprises typically face three challenges: shortage of specialized talent, difficulty in managing complex global supply chains, and the need for rigorous documentation for regulatory compliance. To overcome these, companies should invest in professional training (e.g., ISO 26262-certified engineers), adopt digital tools for traceability and FMEA management, and establish partnerships with international certification bodies like TÜV SÜD or UL. A phased approach—starting with critical functions and scaling to the entire system—is recommended to manage resources effectively.
