This is a collection of research summaries posted to LinkedIn. It’s a work in progress, so expect lots of formatting and spelling errors. I’m gradually adding author details to each summary, but each should at the least have a link to the original study.
*** Importantly, this is a labour of love and NOT a commercial project subject to peer review or double checks. I’ve likely made a lot of mistakes in my analysis of the research. So, please, don’t quote me on anything and instead go to the original source to check the claims. ***
This discussed some of the limitations or considerations in using risk matrices. Given the paper draws on worked examples and figures, I can only give a basic description of a few points and suggest you read the source (which explains the discontinuity between paragraphs in my summary, since I’ve jumped over a lot of supporting… Continue reading Risk matrices: Implied accuracy and false assumptions
Abstract Objective: This opportunistic natural study investigated the effects of relocation of office workers from a 30-year-old building to a new purpose-built building. The new building included an attractive central staircase that was easily accessed and negotiated, as well as breakout spaces and a centralised facilities area. The researchers aimed to determine the impact of… Continue reading Workplace building design and office-based workers’ activity: a study of a natural experiment
This brief paper talks about some challenges with RCA methods. For an article in “the problem with” series, this one is pretty mild and somewhat favourable towards RCA. Since RCA refers to a range of approaches and tools, this looks at more general issues and no particular tool. The authors note upfront that RCA does… Continue reading The problem with root cause analysis
This study looked at the relationships between safety climate, injuries, and setting SMART goals (including goals related to zero injuries). 564 surveys from across 26 high voltage electrical contractors were analysed. Results: 1. Safety climate wasn’t found to be correlated to self-reports of injury, nor to lost-time or no-lost time injury statistics. 2. Safety climate… Continue reading Why Improving the Safety Climate Doesn’t Always Improve the Safety Performance
Abstract Risk matrices are used in process safety to rate and rank risks of hazardous events to help with decision making on risk reduction for processes. For example, commonly they are used in process hazard analysis to rate the risks of hazard scenarios. Flaws in their theoretical framework and mathematical inconsistencies in their use have… Continue reading Designing risk matrices to avoid risk ranking reversal errors
Wrong, but not failed – A study of unexpected events and project performance in 21 engineering projects
This studied the relationship between unexpected events and project performance in 21 projects (which were evaluated 3-12 years after project completion). It’s argued that traditional project management theory often highlights inaccurate foresight, optimism biases and poor planning as key causal factors in unexpected events throughout the project lifecycle. Instead, these authors sought to explore how… Continue reading Wrong, but not failed – A study of unexpected events and project performance in 21 engineering projects
Is perception of safety climate a relevant predictor for occupational accidents? Prospective cohort study among blue-collar workers
This prospective cohort study looked at whether a five-item safety climate survey administered in 2012 was predictive for accidents reported two years later in that sample of participants. 3,864 blue-collar workers were included in the survey study. Being a survey study, it also has the usual limitations, including self-recall of accidents. Safety climate questions were… Continue reading Is perception of safety climate a relevant predictor for occupational accidents? Prospective cohort study among blue-collar workers
Abstract In recent years, the U.S. commercial airline industry has achieved unprecedented levels of safety, with the statistical risk associated with U.S. commercial aviation falling to 0.003 fatalities per 100 million passengers. But decades of research on organizational learning show that success often breeds complacency and failure inspires improvement. With accidents as rare events, can… Continue reading Airline Safety Improvement Through Experience with Near-Misses: A Cautionary Tale
A fantastic read from Gemma Read, Steven Shorrock, Guy Walker and Paul Salmon discussing the history of core theories and methods over the last 60 years around ‘human error’. Also discussed was the human error construct within ergonomics & human factors (EHF), some “key conceptual difficulties” that the human error construct faces in a systems… Continue reading State of Science – Evolving Perspectives on ‘Human Error’
Production pressures in the building sector of the construction industry: a systematic review of literature
This systematically reviewed the evidence around production pressures within the building sector of the construction industry. Specifically, they explored the causes of production pressure, its effects on construction activities, and a review of strategies to minimise its causes and effects. 37 studies were included. Note that the findings themselves won’t be much of a surprise… Continue reading Production pressures in the building sector of the construction industry: a systematic review of literature
