Standard Time

Amount of time a qualified worker specified task, working at should spend to complete a sustainable rate , using tools and equipment, raw material and workplace given methods, Most commonly used methods of work measurement:

Most widely used method of work measurement Especially appropriate for short, repetitive tasks Average of a few properly trained workers’ performed time are taken as the standard Basic steps:

Define the task to be studied, and inform the worker(s) who will be studied

Determine the number of cycles to be observedTime the job and rate the performanceCompute the standard time

Breakdown of work into elements

Work Measurement

Standard Elemental Time (SET) derived from a firm’s own historical time study data

A time study department accumulates a file of elemental times that

are common to many jobs

After a certain point, many elemental times can be retrieved from the


Eliminate need for analysts to go through a complete time study to

obtain those Predetermined Time Standards (PDTS) published data on standard elemental times

Commonly used system is Method-Time Measurement (MTM)MTM tables are based on extensive research of basic elemental times

Work Measurement

Work Sampling is a technique for estimating the proportion of time that a worker or machine spends on various activities and the idle time.

appropriate for long, non-repetitive tasks

Two primary uses:

Ratio-delay studies: concern the percentage of worker’s time that involves unavoidable delays

Analysis of non-repetitive jobs: percentage of time an employee spends doing various jobs

Work Measurement

Observed Time (OT):

simply the average of the recorded times
