How do we translate a paper barrier system into one that’s functional and verified as effective? Whereas part 1 looked at key definitions of control, barrier, safeguard, support, and verification activity – this episode dives deeper into the use of such frameworks. In particular, we unpack escalation / degradation / erosion factors, and the necessary… Continue reading Critical Controls, Barriers, Safeguards: YT Part 2

YT vid: Why Psychological Safety Fails Middle Managers
What if the people in the middle of an organisation are the least safe to speak honestly or take necessary interpersonal risks? Research has suggested that in an ongoing study of over 1000 managers, middle managers felt the least safe psychologically safe compared with c-suite executives and their direct reports. (** Though, as some have… Continue reading YT vid: Why Psychological Safety Fails Middle Managers
What is a ‘system’? Part 1 of 3 extracts from Leveson’s book on systems engineering
What is a system? Post 1 of 3 extracts from Nancy Leveson’s book ‘An introduction to Systems Engineering’. Not reproducing everything from the images – just a few points. This is from a systems engineering perspective. For Leveson, systems engineering considers a system more by its goal or objective, rather than the connected sum of… Continue reading What is a ‘system’? Part 1 of 3 extracts from Leveson’s book on systems engineering
Understanding safety under high workload: adaptive behavior and safety-II mechanisms in healthcare
What does Safety-II tell us about workload, adaptations, and error? This study analysed the effects of workload on error and adaptations across >580 days in 6 hospital departments and 924 reported safety events. PS.

The 90% syndrome in construction safety: distributional concentration of construction accidents in the final project phase
Do construction accidents peak near the end of the project? This analysis of >33k Korean construction accidents examined when accidents occurred during the project phases. They describe the ‘90% Syndrome’, borrowing from the 90-90 rule in software engineering: the first 90% of code accounts for the first 90% of development time, while the remaining 10%… Continue reading The 90% syndrome in construction safety: distributional concentration of construction accidents in the final project phase

Hey nature boy! Greenery and plants are good for yer (#youtube shorts)
Is the amount of greenery and nature around your home or in urban settings linked to depression and other health factors? Based on a number of (mostly observational) studies, cautious links have been established between higher levels of greenness and better sleep, higher physical activity, and lower cardiovascular disease. There are likely lots of explanatory… Continue reading Hey nature boy! Greenery and plants are good for yer (#youtube shorts)
Identifying and Analyzing Resilience Aspects in the ISO 45001 Standard on Occupational Health and Safety Management Systems
How does ISO 45001 contribute to resilient capacities? This interesting study used content analysis and expert judgement evaluation to determine whether the 45001 clauses contribute to resilient capacities. PS.

Challenges in building resilience engineering (RE) and adaptive capacity: A field study in a chemical plant
Can a complex system effectively navigate risk if it only understands failure in hindsight? This study explores the challenges of building adaptive capacity from a resilience engineering perspective in a chemical plant. On-site observations & interviews were used. PS.
