Meaning and Definition
A systematic analysis and detailed recording of the physical movements of a worker or piece of equipment while performing a specific task, aimed at identifying the most efficient method.
The broader application of time-and-motion methodology to any process or activity to eliminate waste, increase efficiency, and optimize performance. Can extend metaphorically to analyzing any sequence of actions.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The practice is associated with the same historical figures (Taylor, Gilbreth) in both regions.
Connotations
May carry a slightly negative historical connotation of dehumanising labour and worker surveillance, though modern lean manufacturing contexts use it positively.
Frequency
Slightly more frequent in American corporate and engineering discourse due to its roots in American industrial engineering.

FAQ
Frequently Asked Questions
Time study focuses on measuring the standard time to complete a task, while motion study analyses the movements themselves to eliminate waste and improve method. They are often combined as 'time-and-motion study'.
Frank Bunker Gilbreth and his wife Lillian Moller Gilbreth are most famously associated with developing motion study techniques in the early 20th century, building upon Frederick Taylor's work.
Yes, but often under modern names like 'process analysis', 'lean manufacturing', or 'ergonomic assessment'. The core principles are integral to industrial engineering and continuous improvement methodologies like Kaizen.
Absolutely. The principles are used to analyse computer workflows, office layouts, and administrative procedures to reduce repetitive strain, minimise clicks, and optimise digital and physical task sequences.
A systematic analysis and detailed recording of the physical movements of a worker or piece of equipment while performing a specific task, aimed at identifying the most efficient method.
