A time and motion study (or time-motion study) is a business efficiency technique combining the Time Study work of Frederick Winslow Taylor with the Motion Study work of Frank and Lillian Gilbreth (the same couple as is best known through the biographical 1950 film and book Cheaper by the Dozen). It is a major part of scientific management (Taylorism). After its first introduction, time study developed in the direction of establishing standard times, while motion study evolved into a technique for improving work methods. The two techniques became integrated and refined into a widely accepted method applicable to the improvement and upgrading of work systems. This integrated approach to work system improvement is known as methods engineering and it is applied today to industrial as well as service organizations, including banks, schools and hospitals.
Time and motion study have to be used together in order to achieve rational and reasonable results. It is particularly important that effort to be applied in motion study to ensure equitable results when time study is used. In fact, much of the difficulty with time study is a result of applying it without a thorough study of the motion pattern of the job. Motion study can be considered the foundation for time study. The time study measures the time required to perform a given task in accordance with a specified method and is valid only so long as the method is continued. Once a new work method is developed, the time study must be changed to agree with the new method.

Famous quotes containing the words time and, time, motion and/or study:
“Twilight and evening bell.
And after that the dark!
And may there be no sadness of farewell,
When I embark;
For though from out our bourne of Time and Place
The flood may bear me far,
I hope to see my Pilot face to face
When I have crossed the bar.”
—Alfred Tennyson (1809–1892)
“There is a time for all things—Except Marriage my dear.”
—Thomas Chatterton (1752–1770)
“I have seen in this revolution a circular motion of the sovereign power through two usurpers, father and son, to the late King to this his son. For ... it moved from King Charles I to the Long Parliament; from thence to the Rump; from the Rump to Oliver Cromwell; and then back again from Richard Cromwell to the Rump; then to the Long Parliament; and thence to King Charles, where long may it remain.”
—Thomas Hobbes (1579–1688)
“Since [Rousseau’s] time, and largely thanks to him, the Ego has steadily tended to efface itself, and, for purposes of model, to become a manikin on which the toilet of education is to be draped in order to show the fit or misfit of the clothes. The object of study is the garment, not the figure.”
—Henry Brooks Adams (1838–1918)
