About this event

A live 30-minute expert session on Writing the SOTIF Verification and Validation Plan — Templates, Scope, and Review Gates (ISO 21448 — Safety of the Intended Functionality). What We'll Cover: What the V&V strategy under ISO 21448 Clause 9 must contain and how it differs from a conventional test plan The construction method step by step: evidence needs per clause, platform allocation (simulation, HiL, track, road), sequencing, and gate criteria How the plan maps to ISO 21448 Clauses 9 through 11 and becomes the master index for all verification and validation artifacts Common mistakes: platform choices without rationale, unknown-scenario activities missing entirely, gates defined but never enforced The traceability assessors check: every triggering condition and hazardous scenario resolvable to a planned activity with a named platform and criterion Related topics: verification validation plan · vv strategy · test platform allocation · review gates · clause 9 · test planning sotif · evidence planning · track testing · road testing scope · plan template · master test index · gate criteria · platform rationale · activity allocation 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.
