Time Study is a systematic method used to measure the time taken to perform specific tasks. By analyzing these times, organizations can identify efficiencies, set time standards, and optimize productivity and processes. This technique is fundamental in industrial engineering and operations management, where the primary goal is to enhance the efficient usage of time, labor, and resources.
History and Development
Origins
Initiated by Frederick Winslow Taylor in the late 19th century, Time Study is part of the larger field of Scientific Management. Taylor’s work aimed to improve industrial efficiency by developing standardized time and motion techniques.
Evolution
Post-Taylor, Frank and Lillian Gilbreth further developed the methodology by integrating motion study and emphasizing worker welfare. Over the decades, the approach has evolved to adapt to various industries and technological advancements.
Purpose and Benefits
Efficiency and Productivity
The primary purpose of Time Study is to enhance efficiency by identifying and eliminating time wastage. It ensures that tasks are performed in the least possible time without compromising quality.
Standard Setting
By establishing time standards, organizations can set benchmarks for task performance, which can be used in performance measurement, workforce planning, and cost estimation.
Methodology
Preparation
- Task Selection: Identify tasks suitable for Time Study.
- Preliminary Observation: Conduct initial observations to understand task complexity and flow.
- Breakdown of Task: Divide the task into small, manageable elements.
Data Collection
- Timing Device: Use a stopwatch or a more sophisticated electronic device.
- Observation: Record the time taken for each element multiple times to ensure accuracy.
- Rating: Evaluate the worker’s performance level to adjust the recorded time to a standard time.
Analysis
- Average Time Calculation: Compute the average time from recorded observations.
- Normalization: Adjust the average time based on the performance rating to get the standard time.
- Allowances: Add allowances for rest, fatigue, and delays to set a realistic time standard.
Example
Consider a simple packaging task. By breaking down the elements—picking the item, placing it in a box, sealing the box, and labeling it—and timing each step, an analyst can identify bottlenecks and optimize the sequence, thus reducing the overall time taken for packaging.
