What you'll learn:
- Understand how ISO 26262 is structured at the concept phase
- Learn how to create the Item Definition
- Do the Hazard Analysis and Risk Assessment by example
- Write the Functional Safety Requirements using an example
Part 3 is where functional safety projects succeed or fail.
Get the Item Definition wrong, and you'll rewrite it three times. Misjudge your ASIL, and you'll over-engineer or under-protect. Miss a hazard in your HARA, and it comes back during assessment.
This course teaches you to do Part 3 right the first time.
I'm Paul Danci, Functional Safety Manager at a German OEM with 15+ years of automotive experience. I've reviewed many HARAs, Item Definitions, and Functional Safety Concepts, and I've seen every mistake. This course shows you exactly how to build work products that pass assessment.
What you'll be able to do:
Write a complete Item Definition document that covers all required content
Structure and execute a HARA that identifies all relevant hazardous events
Determine ASIL levels correctly (and know when B vs A actually matters)
Define Safety Goals with proper safe states and FTTI/FDTI considerations
Create a Functional Safety Concept that flows logically to Part 4
Apply ASIL decomposition correctly and document the rationale
Explain your decisions confidently during confirmation reviews
What's covered:
Item Definition – content, boundaries, interfaces, recipients
HARA methodology – operational situations, hazard identification, S/E/C ratings
ASIL determination – the logic behind the matrix, edge cases, documentation
Safety Goals – safe state definition, FTTI, FDTI, fault tolerant time intervals
Functional Safety Concept – structure, allocation, traceability to Safety Goals
ASIL decomposition – when to use it, how to document independence
Real example: Steer-by-Wire system from Item Definition through FSC
Templates and examples you can adapt to your projects
Who this is for:
Engineers writing their first HARA or Item Definition
Safety managers reviewing Part 3 work products
Anyone who completed the ISO 26262 Crash Course and wants deeper knowledge
Professionals preparing for functional safety assessments
Why this course?
Part 3 has the highest impact on your entire project. The decisions you make here cascade through system, hardware, and software development. Most engineers learn this by making expensive mistakes. This course lets you learn from mine instead.
