The document discusses two key aspects of work study: method study and work measurement. Method study involves systematically examining work processes to develop more efficient methods, while work measurement establishes the standard time needed to complete a specified job. Some benefits of work study include enhancing production efficiency by eliminating waste, establishing time standards, and reducing costs. The work study procedure involves selecting a job to study, recording details, critically examining the current process, developing a more economical method, measuring the work to set standards, defining the new standard, and installing and maintaining it.
