Time and motion study
business efficiency technique

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 studies
Time study is a direct and continuous observation of a task, using a timekeeping device (e.g., decimal minute stopwatch, computer-assisted electronic stopwatch, and videotape camera) to record the time taken to accomplish a task. It is often used if at least one of the following applies:
There are repetitive work cycles of short to long duration.
A wide variety of dissimilar work is performed.
Process control elements constitute a part of the cycle.
The Industrial Engineering Terminology Standard defines time study as "a work measurement technique consisting of careful time measurement of the task with a time measuring instrument, adjusted for any observed variance from normal effort or pace and to allow adequate time for such items as foreign elements, unavoidable or machine delays, rest to overcome fatigue, and personal needs."
The systems of time and motion studies are frequently assumed to be interchangeable terms that are descriptive of equivalent theories.
The public source identifies “Time and motion study” as business efficiency technique. This brief keeps that definition visible, then builds a research path around Time, motion and study.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Time and motion study”, the useful work is to connect “business efficiency technique” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 26, 2026. The linked authority identifier is Q114642. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
