The aim of this case study was to investigate the use of ergonomics information in an engineering design company's design process. Interviews were undertaken with engineers and designers in the company to establish their knowledge of the design process and use of ergonomics in design. Several of the company’s installed designs were also evaluated to identify if the end product of the design process met ergonomics best practice. The results showed that the engineers and designers had poor knowledge of both the formal design processes in use in their company and how to apply ergonomics principles. The installed designs revealed several serious ergonomics problems that could impact on the operators’ ability to work efficiently and safely. Recommendations included improving the understanding and structure of the company’s design process, improving communication, providing adequate ergonomics resources, improving strategies for identification of ergonomics issues in designs and improving quality control of ergonomics issues.
