What are the four basic work measurement techniques?


The four basic work measurement techniques:

  1. Time study
  2. Work sampling
  3. Predetermined motion-time data systems
  4. Elemental data

Step by Step Solution

Time study

Time study, which utilizes a stopped clock to timer the activity, as well as a work sample, that involves capturing randomized views of an individual as well as group at the task, is the direct technique. Time study is an organized technique of directly measuring as well as monitoring human workers with a clocking instrument to determine the necessary time for finishing the project by a competent individual when operating at a set performance level.

Work sampling

Work sampling is a research approach in which employees are watched as well as their actions are documented at randomized periods. The obtained information may be transformed into percentages to show the general distribution of how their time has been spent in separate classes. The statistical approach for calculating the amounts of time employees spend in several specified classes of work.

Predetermined motion-time data system

Predetermined motion-time data systems (PMTS), which aggregate data from a table of generalized moving times produced in the experiment to get at a work time, as well as elemental information, that sums periods from a database of comparable mixtures of movements to reach work time, are the two alternative techniques. The techniques used are determined by the amount of detail sought as well as the type of work themselves.

Schedules, as well as preset motion-time analysis of the data, are frequently required for extremely detailed, repetitive work. The PMTS is a work measuring method that is focused on the breakdown of activity into basic human activities that are categorized depending on the type of every movement as well as the circumstances under which it is performed.

Elemental data

When working with fixed-processing- instruments, elemental data are frequently utilized to decrease the requirement for empirical observation. Sampling work is the instrument of choice when activity is infrequency or has a long cycle duration.
