A time-and-motion study is an analysis of a specific task to determine the actions necessary to complete the task and the time taken to carry out each action. One output of such an analysis could be to determine the most efficient method to complete the task in terms of time and effort. However, the outputs of a time-and-motion study could also be used as input for further studies. The time output of such a study can, for instance, be used as the input into an operational simulation. The motion output can be used for ergonomic design purposes or the development of special tools to assist with operations.
Typical results of a time-and-motion study:
