The historical data method shows the time it actually took to complete a task. Such data have the advantages of being easy to collect, understand, and communicate, but they provide no information for future improvement.
Work measurement methods include time studies, where actual time taken for tasks is recorded; predetermined motion time systems (PMTS), which establish time standards based on predetermined basic motions; work sampling, which involves observing and recording the proportion of time spent on various activities; and standard data, where historical data is used to estimate time requirements for tasks. Each method has its own advantages and is chosen based on the specific context and requirements of the work being measured.
Differentiate between work study and method study.
Method study focuses on analyzing and improving the way tasks are performed to enhance efficiency and effectiveness, often through the evaluation of work processes and procedures. In contrast, work measurement quantifies the time taken to complete specific tasks or operations, establishing time standards for work performance. While method study aims at optimizing workflows, work measurement provides the data needed to assess productivity and efficiency quantitatively. Both approaches are essential for improving operational performance but serve different purposes.

All work measurement systems are based on the same, simple three-stage procedure: analysis, data collection and measurement, and synthesis.
The components of a work measurement system typically include defining the task to be measured, collecting data on the time taken to complete the task, analyzing the data to determine standard times, and establishing performance benchmarks for future reference. Work measurement systems may also involve training employees on proper methods and techniques to optimize efficiency and productivity.
