ABSTRACT
The occupational repetitive actions (OCRA) index is the most precise method for analyzing and evaluating the risk of exposure to repetitive tasks. The method was later followed by various simplified versions, including the OCRA checklists. This book is primarily focused on these simplified analytical models, but this chapter devoted to the original method will, hopefully, enable more expert users to achieve even higher levels of precision, especially when redesigning tasks or, better still, in the design stage itself. The OCRA index is a particularly useful tool for those involved in designing the content and duration of work cycles. The index will help them to monitor and manage not just productivity but also risk levels, the likelihood of occupational diseases and disorders, and therefore also costs. The OCRA method offers the opportunity to conduct an actual cost-benefit analysis.
