About this event

A live 30-minute expert session on Building a Requirements Traceability Matrix That Survives an Audit (V-Model — The V-Model & Safety Lifecycle). What We'll Cover: What an RTM is and how it stitches both sides of the V-model together from hazard analysis to validation Building the matrix step by step: choosing trace granularity, link types, and the decomposition levels to include How the RTM satisfies traceability clauses in IEC 61508 and ISO 26262 and the coverage reports it produces Common mistakes: one-way links, tracing to documents instead of items, and orphan requirements discovered late The bidirectional coverage evidence and orphan/childless queries an assessor will run against your matrix Related topics: requirements traceability matrix · bidirectional traceability · trace links · coverage analysis · orphan requirements · trace granularity · hazard to test traceability · gap analysis · audit evidence · trace queries · decomposition levels · verification coverage · traceability tooling · link types Critical Systems Analysis provides embedded functional safety consulting for V-Model — The V-Model & Safety Lifecycle.

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.
