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.
This quiz covers the concept of work measurement, its application, and uses in establishing the time taken for a job at a defined level of performance. It also detects ineffective time and compares efficiency.
