Chapter 12.1: Systems
‘System’ is a commonly used term in Occupational Health and Safety (OHS) as in, for example, systems of work, OHS management systems and system safety. Systems thinking and system methodologies have a rich history outside the OHS sphere. Examination of the use of ‘system’ terminology within OHS indicates that it frequently refers to a ‘systematic’ approach, or a series of logically ordered steps, rather than what has developed as ‘systems thinking.’ Although a systematic approach is useful, OHS management could benefit from the application of systems thinking and from a viable system approach, which treats organisations as whole entities with interconnected elements, and recognises that a system cannot be entirely understood by examining the parts is isolation. This chapter reviews the development of systems thinking and its historical and present day application to OHS. In presenting the implications for OHS practice it concludes that the optimal OHS outcome can be achieved through an understanding of a system and the application of different systems methodologies at different stages in the OHS risk management process.

Learning Outcomes: Systems
The OHS Body of Knowledge takes a conceptual approach which enables it to be applied in different contexts and frameworks.
To optimise its value for education and professional development learning outcomes have been developed for each technical chapter in the Body of Knowledge.
The learning outcomes as described give an indication of what should be the capabilities of an OHS professional; it is up to those developing OHS education programs, OHS professionals planning their CPD or recruiters or employers selecting or developing people for the OHS function to consider the required breadth vs. depth .
Please read the section on using the learning outcomes before delving into the leaning outcomes of the individual chapters.
AIHS Webinar Systems Thinking
This study presents the first steps in the development and evaluation of an investigation toolkit, the Patient Handling Injuries Review of Systems (PHIRES). The PHIRES Toolkit was developed to help OHS practitioners adopt a systems thinking approach to investigating patient handling injuries, underpinned by Rasmussen’s (1997) risk management framework. This paper presents the key findings from the initial development and usability evaluation of the PHIRES Toolkit conducted with ten health services in Victoria. The findings of this study suggest that the Toolkit is effective in helping practitioners apply system-thinking to understand the complex system of factors involved in patient handling injuries.

Eric Wigglesworth Memorial Lecture: Systems and systems thinking in OHS
Systems thinking is a currently popular philosophy within safety science that is applied to understand and enhance occupational health and safety. This memorial lecture reflects on over twenty years of applied safety research and discusses ten critical lessons learned about OHS management. It includes case study examples covering accident and injury causation, risk and risk assessment, incident reporting and learning, accident analysis, work design, and the development of safety interventions. The practical implications of each lesson learned for OHS are discussed. The lecture closes by looking at emerging challenges for OHS and the need for widespread application of systems thinking.
