Using STPA with software-intensive systems

Tue 19 October 2021 - Paul Albertella

How Codethink are using STPA for risk analysis of software-intensive systems and integrating the outputs into the engineering process.

A new approach to software safety

Thu 20 May 2021 - Paul Albertella

Applying functional safety practices to modern software-intensive systems requires a different approach to the established methods enshrined in current safety standards. Codethink have been working with Exida on a new approach to software safety for systems based on Linux.

Does the "Hypocrite Commits" incident prove that Linux is unsafe?

Tue 11 May 2021 - Paul Sherwood

The recent furore around University of Minnesota’s “Hypocrite commits” research, which spilled over from the Linux Kernel Mailing List and into mainstream tech media, has provoked a lot of discussion about the Linux kernel community’s processes, and arguably provided ammunition to folks who have been saying all along that open source software cannot be trusted.

Safety is a system property, not a software property

Tue 02 March 2021 - Paul Albertella

Applying functional safety practices to software-intensive systems can be very challenging, and established approaches have struggled to scale and adapt to the problem. But what is meant by the assertion that "Safety is a system property, not a component property" and how should this shape our understanding of safety when applied to software?

Meet the Codethings: Safety-critical systems and the benefits of STPA with Shaun Mooney

Thu 04 February 2021 - Yasmin Ferreras Greenwood, Shaun Mooney

In this episode of 'Meet the Codethings', we've asked Shaun about FOSDEM, the future of safety-critical software in automotive, and STPA. Keep up-to-date with our news about safety by just subscribing to our Safety newsletter at the end of the article.

My experience of the MIT STAMP workshop 2020

Tue 25 August 2020 - Shaun Mooney

I recently digitally attended the 2020 STAMP workshop, hosted by MIT. This was originally planned to be in Boston in March, but for obvious reasons was moved.

Open Source Safety Requirements Analysis for Autonomous Vehicles based on STPA

Thu 25 April 2019 - Paul Sherwood

As a result of collaborative research with MIT, Codethink announces a new open source project AV-STPA, to analyse and document safety requirements for autonomous vehicles by applying System-Theoretic Process Analysis.

On our continuing journey to understand the implications of safety and security risk management for complex software-intensive systems, Codethink has …

MIT Doctor delivers Manchester masterclass on innovative safety methodology

Mon 11 March 2019 - Tim Pockney

Systems are becoming more complex than ever before. This now allows us to accomplish tasks that once seemed impossible. With this increase in complexity from systems, there is a need for safety models that can keep up.

STAMP (System-Theoretic Accident Model and Processes) is an accident and causality model based …
