Preparing a Safety Case for ISO 26262:2018 Functional Safety

Course Duration: 2 Days - 8 Hours/day

This two day seminar provides guidance on the development of a Safety Case from the start of a Functional Safety project all the way to design release and to serial production. It will explain how to develop each building block from a safety goal and safety argumentation to the Safety Case.

The building blocks of a Safety Case include: Product and Process argumentation, Nominal performance of Functional Safety (SOTIF), Implementation safety, Development effort safety, Supporting argumentation safety, and Supplier Safety Case.

The approach used in this course integrates the MISRA Guidelines for Automotive Safety Arguments throughout the Safety Case development. These guidelines were developed to support the requirements for a Safety Case in ISO 26262 and provide clarity on how to develop Safety Arguments in line with existing standards.

Who Should Attend

This seminar is designed for those involved in the design, development, and production of electrical and electronic based vehicle products, including the systems, softwareand hardware engineers, and managers. Basically, all those responsible for the development and implementation of hardware and systems in motor vehicles. Omnex has a Software FMEA course for software engineering.

Course Materials

Each participant will receive extensive course material including case studies.

Note: Omnex does not provide copies of standard(s) during training courses, but clients are encouraged to have their own copy.


Participants should be, or plan to be, actively managing or involved in or aware of the development of electrical and/or electronic items, systems or elements that are incorporated in motor vehicles. Participants should also have the abilities, education and experience required for the above roles.
