About this event

A live 30-minute expert session on Preparing for a SOTIF Assessment — Work Products, Interview Questions, and Findings to Avoid (ISO 21448 — Safety of the Intended Functionality). What We'll Cover: What a SOTIF assessment covers, who performs it, and how it slots alongside an ISO 26262 confirmation-measure schedule The preparation method step by step: work-product completeness check per clause, dry-run interviews, evidence indexing, and open-point disposition How the assessment scope maps to ISO 21448 Clauses 5 through 13 and the resulting assessment report and finding-closure records Common findings: acceptance criteria defined after validation, triggering-condition lists with no closure status, field-monitoring process existing only on paper The traceability assessors probe hardest: the chain from hazard to triggering condition to scenario to test result to release argument Related topics: sotif assessment · third party assessment · audit preparation · work product checklist · assessment interview · nonconformity · finding closure · evidence index · confirmation measures · assessment scope · clause walkthrough · readiness review · assessor questions · compliance gaps Critical Systems Analysis provides embedded functional safety consulting for ISO 21448 — Safety of the Intended Functionality.

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.
