Although I don’t often mention or post about Leveson’s work, she’s probably been the most influential thinker on my approach after Barry Turner. So here is a mini-compendium covering some of Leveson’s work. Feel free to shout a coffee if you’d like to support the growth of my site: https://direct.mit.edu/books/oa-monograph/2908/Engineering-a-Safer-WorldSystems-Thinking-Applied https://doi.org/10.1177/0170840608101478 https://doi.org/10.1145/7474.7528 http://therm.ward.bay.wiki.org/assets/pages/documents-archived/safety-3.pdf http://sunnyday.mit.edu/papers/Rasmussen-Legacy.pdf https://www.tandfonline.com/doi/pdf/10.1080/00140139.2015.1015623… Continue reading Compendium of Nancy Leveson: STAMP, STPA, CAST and Systems Thinking

Safety is simple…apparently: two visual representations of the same incident
Safety is simple, bruz … (apparently) (Both examples show the same event, but each uses a different lens. Images are slides taken from one of my presentations to highlight how investigations can be as much ‘constructions’, as searches for ‘objective’ facts, entirely separate to the perceiver or who gets to draw the line in the… Continue reading Safety is simple…apparently: two visual representations of the same incident
A Systems Thinking Approach to Leading Indicators in the Petrochemical Industry
I’m putting together the next Research Compendium, covering indicator definitions, frameworks and examples. Showing my own bias is a focus on Nancy Leveson’s work. This post has some extracts from her article ‘A Systems Thinking Approach to Leading Indicators in the Petrochemical Industry’. This is based on what Leveson calls “assumption-based indicators”. That is, developing… Continue reading A Systems Thinking Approach to Leading Indicators in the Petrochemical Industry
Identifying risks and emergent risks across sociotechnical systems: The NETworked Hazard Analysis and Risk Management System (NETHARMS)
I found this pretty interesting from Dallat, Salmon and Goode, exploring a new systems-based risk assessment method called NETworked Hazard Analysis and Risk Management System (NET-HARMS). One key focus on NET-HARMS was revealing the harder to find emergent risks that emerge via interactions. WAY too much to cover in this paper – I’ve skipped large… Continue reading Identifying risks and emergent risks across sociotechnical systems: The NETworked Hazard Analysis and Risk Management System (NETHARMS)
