Sizing up Australia: The Next Step - Summary

This paper describes the development of the methods and scientific parameters for a proposed Australian Body Sizing Survey. It builds on a previous research that established the need for such a survey. The aim of this research was to learn from others’ experience and establish methods for planning and conducting a robust national sizing survey that would meet the needs of a broad range of anticipated stakeholders. Two further stages are needed before an Australian Body Sizing Survey can be realised: 1) to identify stakeholders, test the survey design against their needs and finalise the method and scientific parameters and 2) to conduct the Australian Body Sizing Survey by collecting raw data according to the agreed method and scientific parameters. In this research we sought answers to basic questions, such as: What should an anthropometric survey deliver? What components make it useful? Will it work? Will it be fit for purpose? The research established the characteristics of a good measurement with examples of the technologies that can produce the necessary quality, while being open to technologies that are under development and might be suitable in the future. We describe a process for sampling that is based upon error estimates from past studies and includes methods for estimating sample size and recruitment strategy. Accuracy, validity and cost-effectiveness are all important considerations and we propose methods that take into account time per subject, size and skill of the data collection team, and the number and type of measurements and demographic variables needed to meet stakeholder requirements. The research examined: 1) factors influencing the budget and resources, 2) international and Australian academic and ‘grey’ literature about national sizing surveys and international standards in other leading countries, and 3) processes to define the scope of the Australian Body Sizing Survey. It addressed the key features of stakeholder engagement and how this would determine the range and type of measurements to be obtained. It also described the systems engineering model that would be used to develop the testing required to finalise the survey method, business plan and costing. It outlined possible sizing survey methods including recommended sampling methods, recruitment strategies and data management. The research findings can be grouped into six key areas that are critical to the effective and efficient development of the Australian Body Sizing Survey. Firstly, 1-D and 3-D data types provide different information and both are essential for a high quality, useful survey. Secondly, new 4-D (high quality 3-D scans captured while the subject is in motion) could provide a cost effective way to capture fit information. Thirdly, it is critical that stakeholders be engaged early in the process. Fourthly, although ISO Standards provide basic templates for the development of a survey, they are not sufficient. Fifthly, a systems-engineering approach balancing technical factors, cost, time, and needs, is required, and lastly, the value propositions from industry demonstrated that a survey conducted in the right way will enable better design and safer and healthier work places and equipment.
