4. At the end of the 19th century, John E
Brooks, grandson of the founder of the
Brooks Brothers firm in the US, came to
England on a European buying trip. While
watching a polo game he noticed
something peculiar about the players
collars; they were buttoned down so as to
prevent them flapping in the wind.
Impressed, John took the idea back to the
Brooks Brothers where they applied
button-down collars to dress shirts.
This shirt was introduced in 1896 and
became the iconic Button-Down formal
shirt, changing the face of menswear
forever. The shirt is said to be 'the most
imitated item in fashion history' and the
Brooks Brothers still call their shirts the
original polo-shirt.

5.  The next date important in
the development of the polo
shirt is 1920. This is the date
that an Argentine-Irish
haberdasher and polo player
named Lewis Lacey opened
a men's shop in Buenos
Aired and began selling a
polo-shirt embroidered with
the image of a polo player

6.  French tennis legend Jean Rene Lacoste
(1904 – 1996); most give him the credit of
'inventing' the modern polo shirt. In a similar
fashion to the polo players of the time,
tennis attire was highly impractical. In the
early 1900's 'tennis whites' were long
sleeved, button-up shirts that were usually
worn with the sleeves rolled up. This
impractical ensemble was finished with
flannel trousers and ties. This came from the
game being originally the preserve of high
society – fashion won over functionality in
these days. As tennis became more
competitive, players began to look for ways
of getting an edge

7. 
The next significant event in the history
of the polo-shirt came in 1972 when
Ralph Lauren wanted to give his new
casual wear company a brand name that
portrayed sophistication and
timelessness. He named it after the sport
of the wealthy and the Royals - Polo. He
included the 'polo-shirt' as a prominent
part of the Polo line which boosted its
popularity further.
The 1980's became the decade of the
polo-shirt as Lacoste and Ralph Lauren
battled for the cash of Americans coast
to coast. Lauren's. With superior
branding and Lacoste over saturating the
market Polo won the battle. It instantly
became an American classic with the
shirt itself developing iconic status as
the embodiment of Polo lifestyle.

8. A polo shirt, also known as a
golf shirt and tennis shirt, is a
form of shirt with a collar, a
placket with typically two or
three buttons,and an
optional pocket.Polo shirts
are usually made of knitted
cloth (rather than woven
cloth) usually piqué cotton or
less commonly silk, merino
wool, or synthetic fibers. A
dress-length version of the
shirt is called a polo dress.

9. SMV means standard minute value. It is a numerical value which is represented the
Standard time of a process or operation in a standard environment for standard worker
To convert cycle time to normal or basic time we have to multiply it with operator
Performance rating.
Standard Minute Value (SMV ) = Basic time + Allowance%
Uses of SMV:
 To Calculate the individual operator targets.
 To Calculate the section targets.
 For man power allocation.
 For product costing.
 For production planning .
 For evaluate the performances.
 For set the incentive levels.

10. The main objective of the study is to determine the main power and
Machine alocation for particular target . it is also designed to address the
following issues:
 To dertermine line balancing.
 To determine operational sequence of the manufacturing process of
polo shirt.
 To develop the target of manufacturing process.
 To increase the productivity of the company.
 To make proper distribution of SMV.
 To make better utilization of man , machine & materials.

14. 
1. Line balancing helps to know about a
new machine required for new style.
2. It becomes easier to distribute
particular job to each operator.
3. It becomes possible to deliver goods
at right time at the agreed upon price.
4. Good line balancing increase the rate
of production.
5. Line balancing help to compare
required machinery with the existing
one and compare balance.
6. IT also help in the determination of
labour requirement.
7. Good balancing reduces production
time.
8. Profit of a factory can be ensure by
proper line balancing.
9. Proper line balancing ensure
optimum production at the agreed
quality.
10. It reduces faults in the finished
product

31.  This project has come to termination finally after lots of thinking
discussion and I uninterrupted trying. I really have worked hard
to complete this project well ahead. I would like to make it as a
replica of production so that it provides a complete knowledge
about Polo-shirt. Through there where some limitation like
shortages of time that compelled me to completed the thesis as
soon as possible, even then I have tried to give my best.As I are
found that SMV for a Polo-shirt is 11.88.I have found during my
thesis that SMV of a Polo-shirt increased in terms of decorative
garments and there is a decrease of productivity.On the other
hand SMV decreased on the less decorative garments.As a result
productivity of garments is increased.Above discussion it is clear
that currect SMV calculation is the key factor for garments
productivity.
