3. Application Of Different Types Study In
Garments Industry

4. INTRODUCTION

5. Work study
Work study is the investigation of work done in an organization in a
systematic process in order attain best possible use of men, materials and
machines available at present.
* The slogan of work study is ‘work smart, not work hard*

6. Objectives of work study
-To standardize the method of doing a task.
-To determine the standard time for doing a task.
-To minimize the materials movements, operator’s movement, idle time
of the workers and machine by proper plan layout.
-To eliminate the unnecessary human motions in performing a task.
-To utilize the facilities such as men, machine or materials most
efficiently and effectively.
-To establish the standard of performance.

7. Technique of Work Study
The methodology of this thesis is the observation, understanding, recording,
improvement, implement of the existing operation condition and find out the
problems then give a suggestion. To increase the production of a company first
of all it is required to collect the data about the production capacity, the total
floor space, total machineries, total worker and minimum clearance between one
work stations to another to perform the best works so that maximum output can
be achieved. Then it is important to practically visualize the existing condition of
the production floor.

8. LINE BALANCING
Line balancing means allocation of machine or work to individual work.
According to the working sheet the step wise setting of machine and work and
individualization of the whole worker into some necessary parts to the worker is
called line balancing.
In garments industry, line balancing is the process of-
-Selecting an effective sewing line
-With competent machines regarding to worker
-To produce a specific order
-A certain time deadline

9. use line balancing technique to achieve:
1. The minimization of the number of workstations
2. The minimization of cycle time
3.The maximization of workload smoothness.
4. The maximization of work relatedness.

10. Objectives of Line Balancing
 -Higher productivity
 -Increased profitability
 -Reduction in work content
 -Simplified work process
 -Greater awareness of equipment
 -Better understanding of how folders and special attachments can influence
productivity
 -Production information and documentation to management

11. Basic tools of work study
There are three basics tools of work study. They are-
1. Work measurement
2. Method study
-Motion study
3. Time study
-Partial work study
-Overall work study

12. Method Study
Latter on the scope motion study was enlarged and it was named ‘Method Study
The British standard Glossary defines method study as
“systematic recording and critical examination of existing and proposed ways of
doing work as means of developing and applying easier and more effective
method and thereby reducing cost.

13. Professional approach of Method study
The main objective of method study is to search for the best method. The searching of
the best method is correct sequence. This sequence of method study is known as
professional approach of method study
The basis pattern can be remembered by the word ‘SREDDIM” Here-
S=Select a word to be studied
R=Record from observation of all relevant facts
E=Examine critically
D=Develop a best method of work place
D=Define a new method which gives best possible returns
I=Install as a standard practice.
M=maintain by regular routine checks

14. Importance of the Method Study
 To study the existing/propose method of doing a job.
 To develop a better method to improve productivity and to
reduce cost.
 To reduce excessive material handling.
 Improve utilization of resources.
 Standardize work method, working condition, machinery
and tools.
 Improved work place lay out.
 Improve work flow.
 Better man power and capacity utilization.

15. Method Study for Garment Operation

16. Method study of activities
 There are following 5 method study activities as described below:
 Operation: An operation is an action performed for advancing towards
a desired result
 Inspection: An inspection is to check that the planned activity has been
performed correctly.
 Storage: Storage occurs when the product is removed for a time from
production

17.  Delay: A delay occurs when some undesired able even prevent the next
planned activity.
Transport: A transport occurs when there are movements from one place
to another.
Combined activities Operation & quality check
Combined activities Quality check then operation

18. Motion Study
Motion study is a technique of analyzing the body motion employed in
doing a task in order to eliminate or reduce ineffective movement and
facilitates effective movement.

19. Principles of Motion Study
There are three principles-
1) Principles related to the use of the ‘human body”
2) Principles related to the ‘Arrangement of the workplace”
3) Principles related to the ‘Design of tools and equipment”
Objective of Motion Study
 -Reduce the no. of motion.
 -Reduce the distance moved.
 -Reduce eye shift.
 -Simply grasps.
 -Best use of both hands.
 -Encourage rhythm.
 -Promote natural posture and movement.

20. Observed time
Observed time comes from a direct observation by an observer that an operator
takes to complete his/her relevant operation or elements.
Performance Rating
Standard performance
Standard Performance is” the optimum rate of output that can be achieved
by a qualified worker as an average for the working day or shift, due
allowance being made for the necessary time required for rest”
Observed rating
Performance rating factor
Standard rating


21. Normal Time
It is the time that a normal operator would be expected to complete a job without the
consideration of allowances. In British Standard it is called basic time.
Normal Time=Average observed time*performance rating factor
Standard Time
Standard time is the time required for an average operator, fully qualified and trained, and
working at standard pace, to perform the operation.
Standard time = Normal time +Allowance
= Normal time +(Normal time*Allowance)
= NT(1+Allowance)

22. SMV(Standard minute value)
SMV is the time taken by a qualified worker to perform a specified task in a defined
level of performance.
SMV calculation
SMV calculation of a basic T-shirt from a time study sheet of a garments industry.
Following formulas are use-
Normal time =Average observed time *performance rating factor
SMV =Basic time +(Allowance *Basic time)

24. Time study
Time study measures the maximum necessary time required to do the job. It is
the most important technique of work measurement. It can be defined as
“Time study is the technique for determining as accurately” as possible from a
limited number of observations.

25. Objects of Time Study
 To determined stander time during which the operation can be performed
efficiently.
 To determined scheduling and planning.
 To calculate fair production per hours.
 Help to the motion study of the job.
 The standard time data is used in time. So a fair entire wage plane can be
established.
 To achieve a uniform flow of work.

26. Element used in the Time Study:
Stop watch: Stop watch is the element which used in time study.
Others: Expect stop watch, following tools may also be used
 Time study board
 Time study form
 Ruler
 Pencil

27. Conclusion
These studies has identified the most pressing needs.By applying these
tasks properly productivity can be increased. By completing the study on
Work study, Motion Study, Time Study we have been experienced that,
these studies how affects productivity in our industries.
It was completely a new experience in our life, which will be very effective
in our practical life.
