2021 STAMP Workshop
Dan Yeaw & Kyle Post
Notes:
Hi my name is Dan Yeaw. I work for Ford Motor Company where I am a Manager and Technical Lead for Functional Safety in Product Development. In my free time, I have been working on an open source tool used to model these complex system designs. That's how I got involved in contributing with Gaphor. I also like to ride bicycles!
Hi I'm Kyle Post. I also work for Ford and I'm the Technical Leader for Systems Safety in the Research and Advanced Engineering area. I have been leading the Risk Analysis and Assessment Modeling Language (RAAML) OMG standard.
We want to build an open community for systems safety
- A low barrier to join, learn, and grow 👥
- Diverse contributors who want to help 🔨
- Built on open standards and open source software
Notes:
- Each industry has developed domain specific standards, most derived fom IEC 61508
- New techniques, like STPA, can improve how we do safety analysis
- However, may lack rigor without a standardized and consistent language and automation
- Precise language for systems safety
- OMG spec 1.0 beta available, final release soon
- STPA metamodel library based on the STPA Handbook
- Facilitates exchange of info between tools and organizations
Notes:
The Risk Analysis and Assessment Language
- An open source UML, SysML, and now RAAML modeling tool written in Python
- Fast and easy to use, while still having a full data model
- Improves rigor through consistency, helps add automation
Step 1: Define Purpose of the Analysis
Step 2: Model the Control Structure
Step 3: Identify Unsafe Control Actions
Step 4: Identify Loss Scenarios
