    Study Notes

    Work Measurement

    • Work measurement is a technique used to establish the time required for a qualified worker to complete a specified job at a defined level of performance.
    • It helps management to measure the time taken for an operation or series of operations, detecting ineffective time and separating it from effective time.

    Objectives and Uses of Work Measurement

    • Compare the efficiency of alternative methods.
    • Balance the work of team members.
    • Determine the number of machines an operator can run.
    • Set time standards for carrying out work.
    • Provide information for estimating tenders, selling prices, and delivery promises.
    • Assist in planning and scheduling production.
    • Provide a basis for realistic and fair incentive schemes.
    • Assist in labor cost control and budgeting.
    • Help in organizing labor by comparing actual times with target times.

    Techniques of Work Measurement

    • Stop-watch time study.
    • Predetermined motion time systems (PMTS).
    • Activity sampling or work sampling.
    • Analytical estimating.
    • Synthesis from standard data.

    Basic Procedure for Work Measurement

    • Select the work to be studied and determine the objectives.
    • Record relevant data and break down the job into elements.
    • Examine the recorded data to ensure the most effective method and motion are used.
    • Measure the time required to complete each element using measurement techniques.
    • Compile the standard time for the operation or work cycle.

    Stop-Watch Procedure for Collecting Time Study Data

    • Establish the quality to be achieved in the product.
    • Identify operations to be timed.
    • Obtain the improved procedure from the method study department.
    • Collect necessary equipment and ensure accuracy.
    • Select the worker to be observed and explain the objectives.
    • Break down operations into small elements and record them on the proper form.

    Analytical Estimating

    • A technique used to estimate time standards for long and non-repetitive operations.
    • It determines time values by using synthetic data or past experience.
    • It involves breaking down the job into elements, selecting time values, and adding a blanket relaxation allowance.
    • Advantages include planning and scheduling, rate fixing, labor control, and possessing the same advantages as synthesis.

    Difference between Synthesis, PMTS, and Analytical Estimating

    • Synthesis builds up total time by adding element times from a catalogue.
    • PMTS deals with basic human motions of duration 0.1 seconds or less.
    • Analytical Estimating differs from PMTS in element duration.

    Predetermined Motion Time System (PMTS)

    • A technique used to measure work times by classifying basic human motions.
    • It is based on the idea that all manual tasks are made up of certain basic human movements.
    • The technique involves selecting a large number of workers, recording job operations on a movie film, and analyzing the film to compile PMTS data.

    Technique of PMTS

    • It does not measure element time by a stop watch, avoiding human judgment.
    • It assumes that the time taken by workers to perform basic movements is practically constant.
    • The technique involves collecting PMTS data by recording job operations on film and analyzing the film to compile data.
