15 Comprehensive Chapters
Each chapter builds your iso 26262 safety lifecycle expertise systematically from foundations to advanced application.
Overview
Introduce the ISO 26262 safety lifecycle as the organizing framework for all functional safety activities from concept to decommissioning.
Concept Phase
Understand the activities of the concept phase: item definition, initiation of safety lifecycle, and hazard analysis and risk assessment.
Item Definition
Create a complete item definition including item functions, operating modes, system boundary, and relevant safety-related interactions.
HARA Phase
Execute the Hazard Analysis and Risk Assessment to identify hazardous events and assign ASIL levels based on severity, exposure, and controllability.
Safety Goals
Derive safety goals from the HARA, specify safe states, and establish the Functional Safety Concept as the top-level safety strategy.
Product Development (System Level)
Execute system-level product development activities from Technical Safety Concept through system design, integration, and validation planning.
HW Development
Manage the hardware development phase from HW safety requirements through architectural design, detailed design, and hardware verification.
SW Development
Manage the software development phase from SW safety requirements through architecture, unit design, coding, and software testing.
Production & Operation
Address production process requirements, field monitoring obligations, and operational feedback loops defined in ISO 26262-7.
Service & Decommissioning
Define service procedures for safety-relevant repairs and updates, and establish safe decommissioning processes for end-of-life.
V-Model Integration
Understand how the ISO 26262 V-model integrates system, hardware, and software development levels with corresponding verification activities.
Phase Gates & Milestones
Define entry and exit criteria for each lifecycle phase gate and establish milestone reviews that confirm readiness to proceed.
Work Products
Catalog all ISO 26262 work products by phase, identify mandatory versus recommended status, and establish documentation standards.
Tailoring Strategies
Apply lifecycle tailoring strategies for different project contexts including derivative projects, pre-existing systems, and time-constrained programs.
Lifecycle Planning
Create a comprehensive Safety Plan that schedules all lifecycle activities, assigns responsibilities, and integrates with the project management plan.

ASIL D EV Battery Management System: Full Safety Lifecycle
An EV manufacturer applied the complete ISO 26262 safety lifecycle to a new battery management system. Meticulous phase gate management and early safety planning reduced the assessment preparation time from the industry average of 18 months to 11 months.
- Safety lifecycle initiated 36 months before SOP with Safety Plan approved at project launch
- HARA identified 42 hazardous events; 11 safety goals derived with ASIL D for battery thermal runaway prevention
- Phase gate reviews at 6 milestones generated 847 documented action items, all closed before SOP
- ISO 26262 functional safety assessment completed with 3 minor findings and zero major findings
