The micromotion study was originated by Frank B. Gilbreth. The study is based on the idea of dividing human activity into division of movements, known as Therbligs. It is the name given to the micromotion of an operation.

The study consists of analyzing a motion picture taken during the performance of work. The time taken for each fundamental motion is accurately indicated in the film by a timing device. The purpose of micromotion study is to assist in finding out the most efficient way of doing work. It also train the individual operator regarding the motion economy principles and help in collecting the motion time data for synthetic time standards.
