What You'll Learn

Build complete competency in software development process through structured, progressive learning.

Plan the Complete SW Lifecycle

Structure an ISO 26262-6 compliant software development process from requirements through verification with appropriate activities at each phase.

Derive SW Safety Requirements

Transform system-level technical safety requirements into complete, verifiable software safety requirements with correct ASIL attribution.

Integrate Agile with ISO 26262

Adapt Agile practices to meet ISO 26262 requirements without abandoning iterative development principles or team effectiveness.

Maintain Bidirectional Traceability

Establish end-to-end traceability across all development artifacts enabling impact analysis, completeness verification, and assessment readiness.

Qualify Development Tools

Assess and qualify compilers, static analyzers, and code generators per ISO 26262-8 Clause 11 with appropriate confidence level justification.

Implement Safety-Aware CI/CD

Design continuous integration pipelines with automated safety gates, regression testing, and compliant change management workflows.

13 Comprehensive Chapters

Each chapter builds your software development process expertise systematically from foundations to advanced application.

1

Getting Started

Orient yourself within ISO 26262-6, understand the scope of software product development, and learn how Part 6 connects to Parts 3, 4, and 5 in the overall functional safety architecture.
