  1. Work Measurement • Vital inputs for: • Manpower planning • Reducing labour costs • Scheduling • Budgeting • Designing incentive systems Standard Time Amount of time a qualified worker should spend to complete a specified task, working at sustainable rate, using given methods, tools and equipment, raw material and workplace • Most commonly used methods of work measurement: • Time study • Historical times • Predetermined data • Work sampling

  2. Work Measurement Time Study • 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 observed • Time the job and rate the performance • Compute the standard time Breakdown of work into elements

  3. 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 file • 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

  4. 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

  5. Work Measurement Observed Time (OT):simply the average of the recorded times Normal Time (NT):observed time adjusted for worker performance Standard Time (ST):normal time required for a job plus an allowance time for different delays For job time For time worked
