About this event
ISO 21448 asks a hard but essential question: what happens when a system behaves as designed, yet still is not safe enough for the real world it operates in? This online session focuses on functional insufficiencies and triggering conditions in a practical, discussion-friendly format, giving attendees a clearer way to think about one of the most nuanced parts of SOTIF work. If you work anywhere near advanced driver assistance, perception, system safety, validation, or safety-related engineering decisions, this meetup is built to help you sharpen your judgment. Rather than staying at the level of abstract terminology, the conversation will center on how to recognize these concepts, analyze them, and talk about them in a way that supports better engineering and better safety cases. About the Event This virtual event is a focused community gathering around ISO 21448 and, specifically, the analysis of functional insufficiencies and triggering conditions. These are core ideas for anyone trying to understand how intended functionality can still create safety risk even when there is no classic fault or failure in the conventional sense. The format is designed to be accessible to both people already working with the standard and those who are still building confidence with the terminology. Expect a session that combines explanation, shared interpretation, and space for discussion, rather than a one-way presentation that leaves no room to test your understanding. Because this is an online event, it is especially well suited for attendees joining from different teams, locations, or backgrounds who want to compare perspectives. The virtual setting makes it easy to attend, take notes, and engage with a community of people thinking seriously about the same technical and safety challenges. This is also a good fit for professionals who want a cleaner mental model for separating issues such as: a limitation in intended functionality an environmental or operational condition that exposes that limitation a hazardous scenario that emerges from the interaction between the two the resulting implications for analysis, validation, and risk reduction What to Expect The session will center on the practical meaning of the topic rather than broad industry commentary. You can expect a structured discussion of how functional insufficiencies are identified and how triggering conditions are characterized in the context of ISO 21448. Likely points of focus include: clarifying the language used in the standard examining how insufficiencies differ from faults understanding what makes a condition genuinely triggering exploring how combinations of assumptions, limitations, and environment shape risk discussing how these ideas show up in analysis and engineering decisions The meetup format also makes room for interaction. Rather than simply listening, attendees should expect opportunities to reflect on how these concepts apply to their own work, compare interpretations with peers, and identify where confusion often arises in cross-functional teams. You should come ready for a session that is thoughtful and technical, but still approachable. Whether you are trying to strengthen your conceptual understanding or pressure-test how your team talks about SOTIF-related scenarios, the discussion should give you concrete ways to frame the problem more clearly. Why Attend Many teams can define ISO 21448 at a high level, but far fewer are aligned on how to reason about insufficiencies and triggering conditions in practice. That gap matters. If these concepts are vague, downstream work in hazard analysis, scenario definition, testing strategy, and safety argumentation can become inconsistent very quickly. Attending this event can help you build a more usable understanding of the topic. Instead of treating the standard as a set of difficult terms to memorize, you will have the chance to work toward a clearer picture of what these ideas are doing and why they matter in real engineering contexts. You may find this especially valuable if you want to: improve how you explain SOTIF concepts to colleagues and stakeholders strengthen the quality of scenario-based analysis better distinguish between performance limitations and fault-based issues ask sharper questions during safety reviews or design discussions connect standard language to practical development and validation work There is also value in the community aspect of the event. Safety-related work often benefits from hearing how others interpret the same requirement space, where they struggle, and what kinds of distinctions have proven useful in practice. Even in a virtual setting, that exchange can sharpen your own thinking. Practical Details This is an online / virtual event, so you can attend from wherever you are without travel or venue logistics. That makes it a convenient option whether you are joining individually, listening in from a home office, or attending alongside teammates from your organization. The event takes place on Monday, August 7 at 5:00 PM PDT. If you are outside the Pacific time zone, make sure to convert the start time in advance so you can join promptly. A few useful things to keep in mind: plan to join on time so you do not miss the framing of the discussion have a stable internet connection and a quiet space if you want to participate actively bring examples or questions from your own work if you want to test how the concepts apply keep notes, especially if you are translating what you learn back to a broader team If you are looking for a serious but approachable conversation on one of the more subtle areas of ISO 21448, this session offers a strong opportunity to deepen your understanding in a format that is easy to access and worth your time.
Who should attend
This session is for people who want a sharper, more practical understanding of how ISO 21448 handles the gap between intended functionality and real-world safety risk. - You should attend if you work in **system safety, functional safety, or SOTIF-related roles** and want to strengthen how you identify and describe functional insufficiencies. - You will get value if you are involved in **ADAS, automated driving, perception, sensing, validation, or scenario-based testing** and need a clearer way to think about triggering conditions. - This is a strong fit if you are an **engineer, architect, analyst, or technical lead** who needs to connect standard language to design reviews, safety analysis, or development decisions. - You should come if you often find yourself asking, **"Is this a fault issue, a performance limitation, or a triggering scenario?"** and want a more consistent framework for answering that. - It is also useful if you work **cross-functionally** and need to communicate these concepts more clearly with teammates in software, systems, test, safety, or product-facing roles. - If you are still building your foundation in ISO 21448 but want a discussion that goes beyond surface-level definitions, this event will help you gain traction quickly.
