Description

The course gives an overview of functional safety basics and explains the parts of ISO 26262 step by step.

The contents of the course are divided into three main chapters:

Motivation
Functional Safety
ISO 26262:2018

Chapter 1: Motivation

In this chapter you get an idea what happens in case functional safety fails. Therefore several real-life examples are explained.

Chapter 2: Functional Safety

In this chapter the history of functional safety is explained. Also the most important terms and definitions in context of functional safety and ISO 26262:2018 are explained. For example functional safety, risk and ASIL.

Chapter 3: ISO 26262:2018

In this chapter the 12 parts of the ISO 26262:2018 are explained step by step. For parts 2-6 you get an overview of all relevant clauses.

The focus of this course is on parts 2-6 of ISO 26262:2018:

Part 2: Management of functional safety
Part 3: Concept phase
Part 4: Product development at the system level
Part 5: Product development at the hardware level
Part 6: Product development at the software level

But also the parts 7-12 are described:

Part 7: Production, operation, service and decommissioning
Part 8: Support processes
Part 9: ASIL-oriented and safety-oriented analyses
Part 10: Guideline on ISO 26262
Part 11: Guideline on application of ISO 26262 to semiconductors
Part 12: Adaption of ISO 26262 for motorcycles

Who this course is for:

Project Leader
Safety Manager
Software Developer
Hardware Developer
Test Engineers
