ISO/PAS 21448:2019 – Safety of the Intended Functionality (SOTIF)

• Basic knowledge of automotive systems
• Basic knowledge of system engineering processes and software development lifecycles

Audience

• Automotive safety engineers
• System and software engineers
• Functional safety managers
• Automotive project managers
• Quality management professionals

ISO/PAS 21448:2019, also known as Safety of the Intended Functionality (SOTIF), is a standard designed to address potential safety risks that arise from functional insufficiencies or misuse of advanced driver assistance systems (ADAS) and autonomous driving technologies.

This instructor-led, live training (online or onsite) is aimed at intermediate-level quality management professionals who wish to learn the concepts, scope, and application of SOTIF for designing, implementing, and verifying the safety of the intended functionality in advanced driver assistance systems (ADAS) and autonomous driving features.

By the end of this training, participants will be able to:

• Recognize potential functional insufficiencies and misuse scenarios.
• Conduct hazard analysis and classify them based on SOTIF principles.
• Integrate SOTIF requirements into the system design, development, and validation phases.
• Implement validation methods to handle edge cases and unforeseeable risks.
• Ensure continuous monitoring and post-deployment improvements to maintain safety.
• Identify and overcome challenges specific to new technologies and SOTIF processes.

Format of the Course

• Interactive lecture and discussion.
• Lots of exercises and practice.
• Hands-on implementation in a live-lab environment.
