Setting the standard: a systems approach to the design and evaluation of safety standards
Tony Carden, University of the Sunshine Coast
This study used Work Domain Analysis, a Sociotechnical Systems method, to evaluate the functional structure of the Victorian Adventure Activity Standards. The analysis revealed significant potential for system improvements. The objects deployed within the system were found to be inadequate to support the purposes of the standards. Implications both for safety standards reform and for the further application of systems methods to regulatory systems are discussed.
The Combat Helmet as a System: Development of a Systems Model to Manage Complexity in Ergonomic Assessments
Sheena Davis, Defence Science and Technology
Whilst the importance of evaluating items of equipment used and worn by soldiers is known, many evaluations focus on a singular aspect. This research adopted a systems approach to identify all ergonomic attributes of a combat helmet and used a systems model to manage and communicate the complexity of the multi-disciplinary attributes. The model provides a foundation for an assessment framework as well a tool to inform design, development, and trade-off decisions.
HSE’s COMAH Requirements – a Systems Ergonomics Approach
Mike Tainsh, Krome Ltd
The Health and Safety Executive (UK), apply the COntrol of Major Accident Hazards (COMAH) regulations during inspections of designated sites. They pay attention to the ergonomics issues associated with the organisation, the jobs and individual characteristics including competency. The organisation needs to scope the ergonomic information, and integrate it appropriately prior to assessment. A User System Architecture (USA) was used to scope and contain all ergonomics information. This supported an integrated understanding of the ergonomics issues, and traceability.
Collisions at Sea: A Systems Analysis of Causal Factors and Countermeasures
Simon Murray, Loughborough University
Despite established and proven prescriptive safety legislation, accidents regularly occur across all sectors of shipping. Of particular concern is the number of collisions that continue to occur, even when experienced and trained officers are on board and modern navigation aids are in use. Using a systems approach, this paper will highlight common contributory factors, which can lead to collisions and then propose a set of countermeasures which can be used to reduce these types of shipping accidents.
Flight Operations as a System of Networks: A Sociotechnical Approach
Neville Stanton, University of Southampton
The study reported in this paper used the Event Analysis of Systemic Teamwork (EAST) method to examine aviation operations from multiple perspectives (Dispatch, ATC/ATM, Maintenance, Loading, and the Cockpit). These networks were created for five key phases of flight: (i) crew briefing, (ii) preflight checks and engines start (iii) taxi and take-off, (iv) descent and landing, and (v) taxi, park and shutdown. The networks have been produced as an ‘information audit’ in order to understand the interactions and connections within the current system.
