Work measurement is the application of techniques which is designed to establish the time for an average worker to carry out a specified manufacturing task at a defined level of performance. [1] It is concerned with the duration of time it takes to complete a work task assigned to a specific job.
Performance measurement is an ongoing activity for all managers and their subordinates. [4] A performance measurement uses the following indicators: Quantity: addresses how much work is produced.
The dimensionally equivalent newton-metre (N⋅m) is sometimes used as the measuring unit for work, but this can be confused with the measurement unit of torque. Usage of N⋅m is discouraged by the SI authority, since it can lead to confusion as to whether the quantity expressed in newton-metres is a torque measurement, or a measurement of ...
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 ...
Staffing (or workforce planning): the number of workers required cannot accurately be determined unless the time required to process the existing work is known. Line balancing (or production leveling): the correct number of workstations for optimum work flow depends on the processing time, or standard, at each workstation.
A work sampling study usually requires a substantial period of time to complete. There must be enough time available (several weeks or more) to conduct the study. Another characteristic is multiple workers. Work sampling is commonly used to study the activities of multiple workers rather than one worker. The third characteristic is long cycle time.
The same setup can be used to instead measure the work function in the collector, simply by adjusting the applied voltage. If an electric field is applied away from the emitter instead, then most of the electrons coming from the emitter will simply be reflected back to the emitter. Only the highest energy electrons will have enough energy to ...
In work measurement, a standard data system (SDS) is a database of normal time values, usually organized by work elements that can be used to establish time standards for tasks composed of work elements similar to those in the database.
