Mini-Compendium: Psychological Safety

Given the prominence of Psychological Safety (PS), it’s worth sharing some research. It’s likely among the most studied modern concepts in organisational theory – so I can barely scratch the surface. Focus first is articles I’ve summarised, and then on any other full-text items I can find. In my haste, I’ve probably included some psychological… Continue reading Mini-Compendium: Psychological Safety

Was meant to be a mini-post. But, too many interesting statements. Extracts: ·         Eastman starts with “So you’ve come to Pittsburgh to study accidents, have you?” says the… Continue reading 1910 Pittsburgh Survey challenging worker ‘carelessness’ as main ’cause’ of accidents

Findings: ·      Inadequate sleep was defined as fewer than 7 h per night ·      1/3 of adults regularly experience insufficient sleep which are “driven by lifestyle factors deeply rooted in modern society” ·      Chronic sleep deprivation has been linked… Continue reading Imbalanced sleep increases mortality risk by 14–34%: a meta-analysis

Human Error: Trick or Treat?

This 2007 chapter from Hollnagel unpacked whether we really need the concept of “human error” (HE). It’s a whole chapter, so I’ve skipped HEAPS. Tl;dr according to Hollnagel: ·         “there is no need of a theory of “human error” because the observed discrepancies in performance should be explained by a theory of normal performance rather… Continue reading Human Error: Trick or Treat?

1912 article discussing the role of fatigue in industrial accidents and arguing against ‘carelessness’ as an “ultimate cause”

This was an interesting article from 1912 highlighting the role that fatigue has in industrial accidents. Also challenges ‘carelessness’, saying it doesn’t account for the effects of fatigue. While scientific knowledge has progressed over the century, it’s cool how well they articulated the issue. ·        Image 1 top panel shows a breakdown of accidents per time… Continue reading 1912 article discussing the role of fatigue in industrial accidents and arguing against ‘carelessness’ as an “ultimate cause”

Chronic unease for safety in managers: a conceptualisation

Human Success: Old wine in new bottles, or a shift of mindset for HRA in an automated world?

A really interesting conference paper from Andreas Bye, discussing whether shifting Human Reliability Analysis (HRA) terminology from human error to human success would help alleviate some of the blame-connotations. Also discussed is the human role in automated systems. It was meant to be a mini-post with a few dot-points and a couple of images, but… Continue reading Human Success: Old wine in new bottles, or a shift of mindset for HRA in an automated world?

What Control Measures Should I Use? Applying the Total Worker Health Hierarchy of Controls to Manage Workplace Fatigue

This new paper from Drew Dawson and others reconceptualised fatigue risk management within Total Worker Health (TWH) Hierarchy of Controls (HOC). THW HOC works as an extension to the traditional HOC, and “presents strategies in order of effectiveness, ranging from “eliminate,” “substitute,” “redesign,” “educate,” and “encourage” categories” They say that while is mostly associated with… Continue reading What Control Measures Should I Use? Applying the Total Worker Health Hierarchy of Controls to Manage Workplace Fatigue

“We miss a great deal when we substitute culture for power” – Charles Perrow on the role of power in disaster

“We miss a great deal when we substitute culture for power” I love this quote from Perrow in Normal Accidents (emphasis added). Perrow briefly discusses the role of power in organising risky technology. Discussing Vaughan’s interpretation of the Challenger disaster: ·        “I also find the role of power and interests minimized in Diane Vaughn’s otherwise excellent… Continue reading “We miss a great deal when we substitute culture for power” – Charles Perrow on the role of power in disaster

Safety Management Systems may struggle with psychosocial factors and other complex phenomena

Certified safety management systems (OHSM) may struggle with complex, multi-factorial matters, like psychosocial safety. Extracts: ·        The OHSM “does not necessarily tackle the most urgent work environment issues and may exclude important aspects of the work environment such as psychosocial factors” ·        “some [OHSM] approaches may be ill-equipped to tackle complex sociotechnical issues and psychosocial matters, and… Continue reading Safety Management Systems may struggle with psychosocial factors and other complex phenomena
