About this event

A live 30-minute expert session on Field Monitoring in the Operating Phase — Closing the Loop on Unknown Scenarios (ISO 21448 — Safety of the Intended Functionality). What We'll Cover: What Clause 13 operating-phase activities require and why field monitoring is the only instrument against residual Area 3 risk The method step by step: trigger definitions for data capture, disengagement and near-miss taxonomies, thresholds for reopening the SOTIF analysis How field monitoring maps to ISO 21448 and produces the field-observation process description and periodic SOTIF review records Common mistakes: collecting terabytes with no triage criteria, no defined threshold that forces action, updates shipped without re-running impacted analyses The evidence auditors seek: a live log of field findings, their classification, decisions taken, and the linkage back to updated scenarios and requirements Related topics: field monitoring · operating phase · fleet data · disengagement analysis · near miss detection · clause 13 · post deployment safety · data triage · continuous validation · sotif update trigger · field observation process · in service monitoring · safety performance indicators · feedback loop 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.
