ISO/IEC/IEEE 15288

ISO/IEC/IEEE 15288 is a comprehensive standard defining system lifecycle processes, from concept to retirement. In the automotive sector, it serves as the overarching framework integrating ISO 26262 functional safety and ISO/SAE 21434 cybersecurity standards. This ensures that safety and security risks are managed holistically rather than in silos, preventing conflicts between safety-critical and security-critical requirements. For enterprises, this means establishing a unified traceability-based approach to manage system complexity and regulatory compliance across the entire lifecycle, which is essential for modern software-defined vehicles (SDVs).

Implementation follows three key phases: 1. Integrated Risk Assessment: Mapping ISO 26262 HARA with ISO/SAE 21434 Threat Analysis and Risk Assessment (TARA) to identify overlapping risks. 2. Unified Control Measures: Designing system controls that satisfy both safety and security requirements simultaneously, reducing redundancy. 3. Lifecycle Verification: Executing verification and validation (V&V) activities at each lifecycle stage as defined by the standard. A Taiwan-based EV component manufacturer implemented this integrated approach, achieving a 30% reduction in verification time and a 20% decrease in rework costs within the first year of adoption.

Taiwanese enterprises typically face three challenges: first, the technical gap in integrating multiple standards, which can be overcome by adopting a unified risk-adjusted lifecycle model. Second, the shortage of engineers proficient in both system engineering and automotive cybersecurity; this requires investment in cross-training and certification programs. Third, the difficulty of scaling these processes across a fragmented SME-heavy supply chain. The solution lies in creating standardized templates and digital traceability tools that can be shared with tier-2 and tier-3 suppliers, ensuring compliance-by-design across the entire value chain.
