This study evaluated whether LLMs can support a scaled and systematic analysis of surveyed data about worker adaptive practices, to foster weak signal ID. E.g. can LLMs help identify weak signals from large-scale data. In this case, textual data describing frontline personnel adaptive behaviours during everyday operations. This was obtained via survey. PS. Check out… Continue reading Tuning into whispered frequencies: Harnessing Large Language Models to detect Weak Signals in complex socio-technical systems

Safer Systems: People Training or System Tuning?
Hollnagel discusses the role of training in complex systems. Shared under open access licence. PS. Check out my YouTube channel: Safe As: A thrifty analysis of safety, AI and risk – YouTube Extracts:· “Safety is usually seen as a problem when it is absent rather than when it is present, where accidents, incidents, and the like… Continue reading Safer Systems: People Training or System Tuning?
Safety-I Versus Safety-II: A Mixed-Methods Study Revealing the Imbalance of Approaches in Primary Care Medication Safety
Extracts from a paper that studied medication safety in primary care from both a Safety-I and Safety-II lens – using “medication management in the wild” as their data. · 2 decades after the ‘To Err is Human’ report has “given way to hard bitten realism that there has been little measurable improvement in the overall rates… Continue reading Safety-I Versus Safety-II: A Mixed-Methods Study Revealing the Imbalance of Approaches in Primary Care Medication Safety
Safe As 30: A better way to think about procedures – resources for action
Do you see procedures as concrete actions that specify the one correct way of working, or more as resources to shape work and sensitise people to risk? Let’s unpack the model 1 / model 2 perspective of rules and see which resonates best with workers. Today’s paper is Hendricks, J. W., & Peres, S. C.… Continue reading Safe As 30: A better way to think about procedures – resources for action
The Folly of Safety-III
Hollnagel’s response to some of the recent (and somewhat bizarre) articles on ‘Safety-III’. Spoiler: It’s not charitable. I’m relying on a lot of direct quotes. Providing context, Hollnagel argues: · Introduction of Safety-I and Safety-II (SI / SII) to characterise two opposite means of safety was “met with surprisingly large interest” and “also with some… Continue reading The Folly of Safety-III
Designing for resilient performance & worker participation: design principles
This review explored how to design for worker participation, drawing on the design of resilient systems. Not much to say – the extracts cover core resilient design principles. Some extracts to contextualise the images: · Participation refers to “the worker’s influence in decision-making related to safety, involving information sharing between people” · “Design for resilient performance Design… Continue reading Designing for resilient performance & worker participation: design principles
Four concepts for resilience and the implications for the future of resilience engineering
An interesting read from David Woods discussing four resilience concepts. Extracts:· While networks of interdependencies have created new value for stakeholders, it has “also created unanticipated side effects and sudden dramatic failures” · The first concept used to describe resilience is rebounding · Rebounding “begins with the question: why do some communities, groups, or individuals recover from traumatic… Continue reading Four concepts for resilience and the implications for the future of resilience engineering
How complex systems (don’t) fail: YT video from late Richard Cook
A banger YT presentation from the late, great Richard Cook. He discusses ‘how complex systems fail’. Video link below. Some extracts: · “The surprise is not that there are so many accidents … The surprise is that there are so few” · “The normal world is not well-behaved … Even so, a lot of operational settings achieve… Continue reading How complex systems (don’t) fail: YT video from late Richard Cook
The human factor: Pursuing success and averting drift into failure – YT video, Sidney Dekker
A 2018 presentation from Sid Dekker on success and drift into failure. One of many such, and no particular reason why this one over any other. Sid starts with an example he heard, supporting the bad apple thesis: “just get rid of the nurses who make mistakes and all will be a lot safer” “Now… Continue reading The human factor: Pursuing success and averting drift into failure – YT video, Sidney Dekker
Compendium of Nancy Leveson: STAMP, STPA, CAST and Systems Thinking
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
