A time and motion study is the analysis of the exact motions required by a person to complete a task, as well as the time required to do so. Once this information has been collected, the analyst devises a more efficient approach by stripping away certain actions and replacing others. Time and motion studies are most commonly applied to highly repetitive tasks, in order to achieve higher levels of labor productivity. These studies are especially necessary in situations where a business is trying to drive down its costs to become the low-cost, high-volume producer in an industry. This approach is not cost-effective for tasks that are not repeated on a regular basis, since the offsetting efficiency improvements do not pay for the cost of the study.
