Objectives of project work:
To implement of work study charts to obtain
maximum utilization of the resources and to
optimize workplace by changing.
Role of industrial engineering department in
Importance of industrial engineering (IE) tools that can be used
to improve upon the productivity and thus enhance the profits.
Very few companies have been operating with a full fledged
industrial engineering department and even those which boast of
as an industrial engineering department(IED) are not allowing
freedom and scope to function to its full capabilities. The role of
IED is important for the garments industry for the following two
It’s highly labor –intensive industry.
Effective planning is emerging as one of the key factors for
the garments manufacturing industry.

Finished garments to warehouse
What is work study?
Work study is mainly concerned with the examination of
There are two parts of work study:
Why work study?
• To eliminate wastage of time and labor.
• To reduce fatigue and boredom of work by avoiding
• To find a best way of doing a job.
• To have more utilization of materials, machines and
• To improve the design of work place layout.
• To train the individual operator in its practice as per
Why Work Measurement is Important?
Production planning and
• Determine cost
The main purpose of method study is to
eliminate the unnecessary operations and
to achieve the best method of performing
To determine the time it should take for a
qualified worker to perform a specific
task using a specified method by directly
observing an operator.
Time Study Sheet of IE Department:
How it Works?
Compute the basic time
Basic Time = Observed time X
Compute the standard minute value
SMV = Basic Time + Allowance
In this case, we need to follow PDCA process improvement
chart which can give us a solution.
Figure : The Shewhart Cycle is a fundamental idea for continuous process improvement.
Quality means customer satisfaction
Benefits of TQM:
The benefits of TQM can be classified into the following two categories:
1. Customer satisfaction oriented benefits.
2. Economic improvements oriented benefits.
1. Customer satisfaction oriented
this category are listed below:
(a) Improvement in product quality.
(b) Improvement in product design.
(c) Improvement in production flow.
benefits: The benefits under
2. Economic improvements oriented benefits: The benefits
under this category are as follows:
(a) Reductions in operating costs.
(b) Reductions in operating losses.
(c) Reductions in field service costs.
(d) Reductions in liability exposure.
Time Study Exercise
= Side Seam
Observed Time = 35.27 Sec
Observed Rating = 92%
= (35.27 X 0.92) Sec
= 32.45 Sec
= 32.45 + (32.45 X 0.25) Sec
= 40.56 Sec
= (3600 ÷ 40.56) Pcs/ Hour
= 88 Pcs/ Hour
Investing in training and the development of employees.
Investing in better plant and equipment.
Management – Worker
Improving the planning or work
Improving methods of production
Effective worker selection process
Ways of improving productivity
– improving worker effectiveness
– Providing workers with
– Improving morale
– Rewarding success
– Improving attendance levels
– Reducing labour turnover
– Effective communications
– Measuring the performance.
WITH THE APPLICATION OF WORK STUDY CHARTS
IN APPAREL MANUFACTURING, THE EFFECTIVE
UTILIZATION OF RESOURCES ( MAN, MATERIAL &
MACHINES) CAN BE ACHIEVED.
THE COST INVOLVED IN USING THESE CHARTS ARE
VERY MINIMUM AND A SOLUTION CAN BE DERIVED
IN A SHORT PERIOD OF TIME.
