Work Measurement in Garment Industry

Work measurement:
Work measurement (WM) is the application of different techniques designed to establish the time for a qualified worker to carry out specified jobs at a desired level of performance. Most activities of work measurement in textile and apparel industry are done by industrial engineering department. Work measurement can be used in cutting section, sewing section and finishing section as well. WM is very important in garment manufacturing because of using work measurement data you can estimate only direct labor cost of garment making. In this article I have given a basic concept of work measurement which may be effective for textile engineers.

We can easily understand that total time to manufacture a product is increased or delayed by:
  • Adding undesirable features to product,
  • Bad operation of the processes and
  • Ineffective time added because of worker and management.

All this leads to decreased productivity. Work measurement (WM) is concerned with investigating, reducing and elimination ineffective time, and increasing productivity. However, WM consists of two basic study techniques:
  1. Direct techniques: Time study and activity sampling.
  2. Indirect technique: Synthetic times, PMTS and analytical estimating.
More features about WM:
  • It is the means of measuring the time taken in the performance of an operation or series of operations in such a way that the ineffective time is shown up and can be separated out.
  • In practice, proving existence of the ineffective time is the most difficult task.
  • After existence is proved, nature and extent is easy to see.
  • WM is also used to set standard times to carry out the work, so that any ineffective time is not included later.

Objectives of work measurement:
Establishing a Standard Time is the main aims of work measurement, which is the required time to perform a given task. The purposes or objectives of work measurement are given below:
  • To reveal the nature and extent of ineffective time, from whatever cause, so that action can be taken to eliminate it.
  • To set standards of performance that are attainable only if all avoidable ineffective time is eliminated and word is performed by the pest method available.
  • To compare the efficiency of alternative methods. Other conditions being equal, the method which takes the least time will be the best method.
  • To balance the work of members of teams, in association with the multiple activity charts, so that, as far as possible, each member has tasks taking an equal time.
  • To determine, in association with man and machine multiple activity charts, the number of machines an worker can run.
Techniques of work measurement:
Various techniques of work measurement are:
  1. Time study (stop watch technique): It is the basic technique of work measurement.
  2. Synthesis from standard data,
  3. Work sampling,
  4. Predetermined motion time systems,
  5. Estimating,
  6. Analytical estimating.
  7. Comparative estimating etc.
Uses of work measurement:
Work measurement helps to uncover non-standardization that exist in the workplace and non-value adding activities and waste. A work should measure for the following reasons:
  1. In the process of setting standards it may be necessary to use work measurement.
  2. To discover and eliminate lost or ineffective time.
  3. To compare the efficiency of alternative methods.
  4. To set operating goals and objectives.
  5. To measure performance against realistic expectations.
  6. To balance the work of members of teams.
