David has been a thought leader in Human Factors for over 40 years. He has worked internationally on Human Performance in many countries, including the USA, Singapore, and Brazil. He has published more than 140 papers, and a standard textbook on Human Factors: ‘Guidelines for Reducing Human Error in Process Safety’ for the Centre for Chemical Process Safety (USA).
David has conducted human reliability analyses in many sectors, including process safety, healthcare, and medical devices. He developed the Systematic Human Error Reduction and Prediction Approach (SHERPA) which has helped clients in managing human performance effectively. This laid the foundation for methods such as Safety Critical Task Analysis (SCTA) which is required by the UK regulator for COMAH sites. SHERPA is now a software platform which allows engineers and safety professionals to conduct human factors risk assessments, develop better procedure, training aids and conduct other human performance-related analyses.

Lydea Soh holds a degree in Psychology from the University of Manchester and an MSc in Human Factors and Ergonomics from Loughborough University. Since joining HRA, she has developed her skills and knowledge in carrying out SCTAs in the process industries to gain her Chartership from the CIEHF. In addition to consultancy work, she supports the trainers in the SCTA course and the Introduction to PLC course.
“My first exposure to Human Factors was during college. My professor showed a video detailing the Challenger space shuttle disaster and this sparked an interest in understanding the various contributing factors that lead up to accidents and incidents. Upon further reading, I realised how intricate Human Factors is and its role in our day-to-day life. I was completed intrigued by this field, which prompted me to pursue my tertiary education in this field and to start a career in Human Factors.”
