New STAMP/STPA modeling tool – STAMP Workbench – released!

IPA-logo.gifOn March 30th 2019, Information-technology Promotion Agency, Japan(IPA) released the first edition of their STAMP/STPA modeling tool called “STAMP Workbench” and we’re pleased and proud to announce that this tool uses Astah as its platform.

blubar-big So what is STAMP and STPA?

STAMP (Systems-Theoretic Accident Model and Processes) is a new accident causality model based on systems theory and systems thinking developed by Prof. Nancy Leveson at the Massachusetts Institute of Technology. STAMP integrates into engineering analysis the causal factors in complex systems such as software, new technology and safety culture.


STPA Handbook

STPA (Systems-Theoretic Process Analysis) is a powerful new hazard/cybersecurity analysis technique based on STAMP. You can download STPA Handbooks (available both in English and Japanese) from MIT PSAS Site.

IPA has been conducting their deep research of STAMP and STPA, survey of safety analysis and evaluation processes in Japanese software development industries and finally released their first edition of the tool, not only for researchers but anyone who’d like to implement STAMP/STPA in actual industries.
So they have opened the door for Japanese industries and gave us a tool. If you are familiar with Astah already, you will pick it up quickly. Even if you are not, a manual will help you start out.

  1. Where do I report bugs? I have tried a few links but no responses. The bug is relatively serious as it breaks diagrams that have nested components. Makes the tool less useful for managing complex designs and so likely less useful in real applications. I have warned Dr Johnson at MIT to avoid assurance problems on real projects. The tool might be useful for training in STPA as long as nested designs were avoided.
