About this event

A live 30-minute expert session on Audit vs Confirmation Review vs Assessment in ISO 26262 (FSA & Services — Assessment & Services). What We'll Cover: Where confirmation reviews, the functional safety audit, and the functional safety assessment sit in the ISO 26262-2 framework Step by step: identify the work products needing confirmation review, plan the audit of processes, then scope the assessment of the achieved safety How each maps to ISO 26262-2 Clause 6.4.9 onwards and the reports each measure produces Common mistakes: treating the audit as a document review, or one person performing all three measures on the same item Evidence auditors look for: confirmation review checklists per work product, audit records against the safety plan, and the assessment report before release Related topics: confirmation measures · confirmation review · functional safety audit · iso 26262-2 · asil dependent measures · safety plan audit · release for production · confirmation review checklist · work product review · process audit · achieved functional safety · independence requirements · safety case review Critical Systems Analysis provides embedded functional safety consulting for FSA & Services — Assessment & Services.

About Functional Safety Foundations

This online session delivers expert-led instruction on the regulatory landscape and implementation approach for Functional Safety Foundations.

The cross-sector fundamentals underlying every functional safety standard: risk as severity × likelihood, the safety function concept, integrity levels, the safety lifecycle, and the split between random and systematic failures.

What it regulates

Shared vocabulary and reasoning: hazard → risk → risk reduction allocation → safety requirement → verified implementation → maintained integrity in operation.

Who must comply

Everyone entering the field — the conceptual base of the entire catalog.

Key requirements of Functional Safety Foundations

  • Hazard and risk fundamentals
  • Safety function anatomy: sensor-logic-actuator with defined safe state
  • Integrity ladders (SIL/PL/ASIL/DAL) as risk-reduction currencies
  • Random vs systematic failure treatment
  • Lifecycle and management of functional safety incl. competence

Key concepts: Functional Safety Foundations

Functional safety management
Planning, competence, documentation and assessment wrapped around technical work.
Random vs systematic
Hardware wear-out/chance failures quantified statistically versus design/process errors controlled by rigor.
Risk reduction allocation
Distributing required risk reduction among mechanical design, safeguards, control functions and procedures.
Safe state
The defined condition a function drives the equipment to on demand or fault.

Frequently asked questions: Functional Safety Foundations

Why can't testing alone prove safety?

Rare-event targets (like 1e-7/h) are unverifiable by test duration, and systematic errors evade random testing — hence the standards' dual machinery of quantified hardware analysis plus process rigor and independent assessment.
