P a g e 6 | 43History
Founded by Jamshedji TATA in 1868, Tata’s early years were inspired by the spirit of
nationalism The modern iron and steel industry in India owes its origin to the grand vision
and perseverance of Jamshedji Nusserwanji Tata. The Tata Iron and Steel Company Limited
(Tata Steel) was registered in Bombay on 26th August 1907. The construction of the steel
plant was then taken up in earnest with the first stake being driven in February 1908. R.G.
Wells, an American with steel plant construction experience took over as the General
Manager in 1909. Success came when the first blast furnace was blown-in on 2nd December
1911, and the first ingot rolled on 16th February1912.
The story of the Tata Group of business unfolds with the birth of its founder Jamshedji Tata
in the small town of Navasari in Gujarat in 1839. He breathed his last in 1904 in Germany.
His parents were Nusserwanji and Jeevanbai Tata. Nusserwanji was the first businessman in
a family of Parsi Zoroastrians priests. Destiny called him to Bombay where he started
trading. Jamshedji joined him at the tender age of fourteen.
He took admission in Elphinstone College and while still a student he married Hirabai Daboo.
Jamshedji graduated in 1858 and joined his father’s trading firm. Those were turbulent
times. The British had just managed to ruthlessly crush the 1857 Revolt. Since the age of
twenty-nine Jamshedji continued to work in his father’s firm. In 1868 he started a trading
company on his own with a capital of Rs.21, 000/- Founded by Jamshedji TATA in 1868,
Tata’s early years were inspired by the spirit of nationalism The modern iron and steel
industry in India owes its origin to the grand vision and perseverance of Jamshedji
Nusserwanji Tata. His first step was to acquire a bankrupt oil mill and convert it into cotton
mill which he renamed Alexander Mill. Two years later he sold it with a good margin of
profit. With this he set up a cotton mill in Nagpur in 1874. Queen Victoria had just been
declared the Empress and in keeping with the times Jamshedji named it Empress Mill.
Jamshedji was a unique personality. He did not just think of innovative ways of P a g e 7 | 43
A) THE BEGINNING
OF TATA
manufacturing textiles but he devised new labour practices that would satisfy the workers.
In this way he was far ahead of his times.
It was not just his own personal success but also of those who worked for him and his
group. Jamshedji was in close contact with revolutionary thinkers and nationalists like Dada
Bhai Naoroji and Pherozeshah Mehta and strongly influenced by them. He came to the
conclusion that economic self-sufficiency should go hand in hand with political
independence. The former should be the base of the latter. Jamshedji had three key ideas in
mind. He wanted to set up an iron and steel company, world class learning institution and a
hydroelectric plant. Unfortunately during his lifetime none bore fruit but he had planted the
seed, which later took roots and spread its branches under the care of his successors. The
only achievement that he lived to see was The Taj Mahal Hotel.
It was completed in December 1903 for a princely amount of Rs.4, 21, 00,000/-In this too he
was inspired by nationalist thinking. In those days the locals, that is Indians, were not
allowed into the best European Hotels. Taj Mahal Hotel was a befitting reply to this
discrimination. Tata Group is a private conglomerate with headquarters at Mumbai. The
present Chairman is Ratan Tata who took over from J.R.D. Tata in 1991.
A member of the Tata family is always the Chairman of the group. Its operations covers
many fields related to industry and allied activities concerned with know-how and its
application –engineering, information technology, communications, materials,
automotive, chemicals energy, telecommunications, software, hotels, steel and consumer
goods. Â The statistics and figures of Tata Group speak for themselves. Its revenue touches
$967,229 million or $21.9 billion in 2005/06. This is equal to 2.8% of India GDP. There are
about 246.000 employees in the Tata group as per records of 2004. Market capitalization
figure is $57.6 billion. There are ninety-six companies operating in seven business sectors.
 Only twenty-eight of the ninety-six in Tata Group are publicly listed. Tata operates in more
than forty countries across six continents. It exports products and services to one hundred
and forty nations. The Charitable trust of Tata holds 65.8% of the ownership of Tata group

TISCO now called Tata steel set up in 1907 INDIA’s first iron and steel plant in Jamshedpur,
which is often called Tatanagar. Production actually started in 1912. It produces steel at the
lowest cost in the world. This is mainly because it is assisted by group member concern that
deals with the supply of raw material like coal
and iron. In 1910 was set up Tata Hydro-Electric Power Supply Company. In 1917 the Tata
group made its debut in the field of consumer goods industry with the setting up of Tata Oil
Mill dealing in soaps, detergents and cooking oil. 1932 saw the establishment of Tata
airlines. Tata Chemicals made its appearance in 1939. Telco now known as Tata Motors
started to manufacture locomotive and engineering products from 1945. January 2007 is a
watershed in the history of Tata Group. Tata steel made a successful bid for UK based Corus
Group, which was one of the world’s leading steel and aluminium producers. After an
unprecedented nine rounds of bidding Tata finally clinched the deal. Tata offered to buy
100% stake in Corus at 608p per share (all cash) totalling to a value of $12.04 billion. It has
turned out to be the biggest acquisition by any Indian company.
Tata Power is one of the largest private sector companies in India and supplies power to
Mumbai and parts of New Delhi. Then there are Tata Chemicals and Tata Pigments. In the
service sector there are Tata companies dealing with hotels, general insurance and life
insurance. Tata offers management, economic and financial consultancy services. Tata is
one of the best names in the world of investments and shares. In the area of education
Tata’s publishing house of Tata McGraw Hill is a renowned name.
Tata Motors is India's largest automobile company, with consolidated revenues of $ 32 billion in 2011-12. Through subsidiaries and associate companies, Tata Motors has

operations in the UK, South Korea, Thailand and Spain. Among them is Jaguar Land Rover, the business comprising the two iconic British brands. It also has an industrial joint venture with Fiat in India. With over 4 million Tata vehicles plying in India, Tata Motors is the country’s market leader in commercial vehicles and among the top three in passenger vehicles. It is also the world's fourth largest truck manufacturer and the second largest bus manufacturer. Tata cars, buses and trucks are being marketed in several countries in Europe, Africa, the Middle East, South Asia, South East Asia and South America.

PLANT A) ABOUT PANTNAGAR PLANT
B) HOLISTIC VIEW TATA MOTOR PANTNAGAR
The company has set up a plant for its mini-truck Ace and the passenger carrier Magic
(based on the Ace platform) at Pantnagar in Uttarakhand. The plant began commercial
production in August 2007. This is the company's fourth plant, after Jamshedpur
(commercial vehicles), Pune (commercial vehicles and passenger vehicles) and Lucknow
(commercial vehicles). The plant is spread over 953 acres, of which 337 acres is occupied by
the vendor parts.
State-of-the-art facilities include weld shops, paint shops, engine and gear box shops and
assembly lines. The company has invested over Rs.1250 cores in the plant. Vendors for the
P a g e 11 | 43
vehicle have made additional investments to set up their plants in the vendor park
adjoining the plant. The operation has generated about 7500 direct and indirect jobs in the
plant, among vendors and service providers in the area. It was also acting as a backup plant
for NANO. As the problem arise there in Singur it was decided to start production of NANO
from this plant in the meantime a full-fledged plant is being constructed for NANO at
Sanand, Gujarat. So, this plant is getting the opportunity to deliver peoples car to the
people.
Now, the NANO production has been shifted to Sanand in Gujarat. The plant is now acting
home to various new products to be soon or has been already launched by TATA MOTORS.
It is now producing TATA ACE (.75Ton), Super ACE (1Ton), Magic, Magic Iris, Zip and
Venture. Venture is being produced in 2 variants and is also exported out of India. Magic Iris
and Zip are yet to be launched.

MANUFACTURING SHOPS IN PANTNAGAR PLANT
Pantnagar has four shops for manufacturing of vehicles. The shops are:
1. ASSEMBLY SHOP -Assembly shop is also known as TCF Shop (TRIM CHASSIS FINAL). In this
shop all the assembly works like the assembly of trims, seats, ccb, window glass, doors
engine, and Suspension, Tyres, Headlamps, Tail lamps, and Dashboard etc. fittings is carried
out. This shop can be thought of as the organ fitting shop in to the skeleton body of the car.
Car enters this shop as a skeleton chassis cab and the final product of the shop is fully
completed vehicle. There are presently 4 assembly shops – TCF 1A, TCF 1B, TCF 1C AND TCF
1D.
2. WELD SHOP –Weld shop is also known as BIW Shop (BODY IN WHITE).Here different parts
are welded together and the whole structure of the car is built including the chassis frame.
This shop plays critical role in maintaining the dimensional accuracy which would otherwise
lead to major assembly-line problems and major downtimes in their correction The weld
shop is divided into 5 sections namely, BIW 1A, 1B, 1C, 1D, 1E.
3. PAINT SHOP – The TAIKISHA paint shop is the beauty parlours of the car plant. This shop
paints the car in various shades. This is the most sophisticated shop of the plant. It uses
world class technology for painting the vehicles. The most interesting point of this shop is
that all vehicles, no matter which type, are all painted under the same shop together. Thus
the paint shop has to work 4 times faster than the TCF, so that body reaches each of the
assembly shops. It takes 18 steps spread over less than 10 hours to accomplish the task.
Tata Motors Pantnagar boasts to have the biggest atomized Paint shop in whole of Asia.
4. POWER TRAIN SHOP – This shop is divided into Gear Train and Engine shop. This shop
takes care of the assembly of the engine and the assembly of the gear box. The engine and
the gear box are assembled separately but are coupled at the end of the line.

Kaizen
Kaizen is a Japanese word which is the combination of two words. (Kai—continuous
&Zen—improvement)Kaizen leads to the bigger improvement of the organization. It
is continuous improvement through self-realization. It is for safety, quality, cost,
delivery, moral, and environment. Kaizen involves looking at the current state of
process, separating value added from waste and making it right by using principle of
improvement, to leave out a waste and built a better process.
"CHANGE FOR THE BETTER" Kaizen = Continuous Improvement
...by Everybody! Everyday! Everywhere!
P a g e 24 | 43
System Followed
in TML
o Kaizen Cycle
The cycle of kaizen activity can be defined as:
Standardize an operation and activities,
Measure the operation (find cycle time and amount of in-process inventory).
Gauge measurements against requirements.
Innovate to meet requirements and increase productivity.
Standardize the new, improved operations.
Continue cycle ad infinitum
P a g e 25 | 43
o Kaizen Exercise/Event
What is a Kaizen Event?
A Kaizen event is an exercise planned and organized in a specific workshop over a set period of time to inspect and improve process flow, address recurring defects and problems and ensure better quality standards of products.
Aim
Any Kaizen exercise aims at continuous improvement in process flow and finding ways and means so as to remove defects and ensure better overall quality standards.
P a g e 26 | 43
o BENEFITS
Benefits can be measured in the form of following factors
P- PRODUCTIVITY
Q- QUALITY
C- COST
D- DELIVERY
S- SAFETY
M- MORALE
E- ENVIRONMENT
o NEED OF KAIZEN
To reduce the cost by improving productivity.
To improve the quality of the product.
To reduce the cost to compensate for the increased cost of inputs.
To improve the delivery of the product and reduce the lead time.
To improve the morale.
To remove the chances of accident
o Methodology
Kaizen event adopts the following series of operation to address the problems occurring in a particular shop/station-
1. Problem Description – In this opening stage, we define the problem at hand.2. 5W1H Analysis - This is a technique used to inspect the problem defined in step 1. 5W1H implies:
P a g e 27 | 43
a. What- What is the defect?b. Where- Where is it occurring?c. When- When is it taking place?
d. By whom- Who reported the defect?e. Why- Why is it occurring?f. How- How is it taking place?
3. 4 M Analysis – 4 M Implies Man, Machine, Material and Method. This assess-ment technique strives to investigate whether the cause of the problem is re-lated to Man (the operator), Machine (faulty equipment’s), Material (the work-piece) or the Method (process) employed by the operator.
4. 5 Why Analysis –is a form of root cause analysis in which the user asks a se-ries of 5 "why" questions about a failure that has occurred, basing each sub-sequent question on the answer to the previous. There are normally a series of causes stemming from one root cause, and they can be visualized using fishbone diagrams or tables. For example-
The vehicle will not start. (The problem)
1. Why? - The battery is dead. (first why)2. Why? - The alternator is not functioning. (second why)3. Why? - The alternator belt has broken. (third why)4. Why? - The alternator belt was well beyond its useful service life and not replaced.
(fourth why)5. Why? - The vehicle was not maintained according to the recommended service
schedule. (fifth why, A Root Cause)
The questioning for this example could be taken further to a sixth, seventh, or higher level, but five iterations of asking why is generally sufficient to get to a root cause. The key is to encourage the trouble-shooter to avoid assumptions and logic traps and instead trace the chain of causality in direct increments from the effect through any layers of abstraction to a root cause that still has some connection to the original problem. Note that, in this example, the fifth why suggests a broken process or an alterable behavior, which is indicative of reaching the root-cause level.
It is interesting to note that the last answer points to a process. This is one of the most important aspects in the 5 Why approach - the real root cause should point toward a process that is not working well or does not exist. [2] Untrained facilitators will often observe that answers seem to point towards classical answers such as not enough time, not enough investments, or not enough manpower. These answers may be true, but they are out of our control. Therefore, instead of asking the question ‘why?’ ask ‘why did the process fail?’
A key phrase to keep in mind in any 5 why exercise is "people do not fail, processes do".

The 5S Methodology
5S is a system to reduce waste and optimize productivity through maintaining an orderly workplace and using visual cues to achieve more consistent operational results. Implementation of this method "cleans up" and organizes the workplace basically in its existing configuration, and it is typically the first lean method which organizations implement.
The 5S pillars, Sort (Seiri), Set in Order (Seiton), Shine (Seiso), Standardize (Seiketsu), and Sustain (Shitsuke), provide a methodology for organizing, cleaning, developing, and sustaining a productive work environment. In the daily work of a company, routines that maintain organization and orderliness are essential to a smooth and efficient flow of activities. This lean method encourages workers to improve their working conditions and helps them to learn to reduce waste, unplanned downtime, and in-process inventory.
