TATA NANO MANUFACTURING Khushiyon ki chaabi

Agenda I. II. III. IV. V. VI. History Introduction Technical specification The Strategy Supplier relation Assembling

 Ratan Tata was the chairman of the TATA company since 1991 to 2012.  It is diversified in 90 companies like Tata steel, Tata salt, Tata chemicals, Tata motors, Titan, Tata Telecom etc…  This company is serving INDIA for over 130 years  This company continuously upgrades technology with tie ups & collaboration with global companies

THE SEEDS OF DREAM The dream stared when Ratan Tata saw a family of four people (Husband, wife & two children) going on two-wheeler on heavy rain in highly risky conditions…But in India it’s a very common scene. Mr. Ratan Tata said, “I observed families riding on two-wheelers - the father driving the scooter, his young kid standing in front of him, his wife seated behind him holding a little baby. It led me to wonder for such a car which is safe & affordable to any middle class family.”

INTRODUCTION • Tata Nano is a proposed city car — a small, affordable, rear-engined, four-passenger car aimed primarily at the Indian market. • Presented by India's Tata Motors at the 9th annual Auto Expo on January 10, 2008 at Pragati Maidan in New Delhi, India.

ABOUT PLANT • Situated in Singur West Bengal • Investment of 1500cr. rupees by Tatas. • Shifting cost of the plant from singur is around 500 cr. • Total area of plant is 1000acres out which 300 acres were alloted for assembling of various parts and rest 700 acres for manufacturing.

AIM OF MAKING • The project to create the world's cheapest car inspired by the number of Indian families with two-wheeled rather than four-wheeled transport.

TECHNICAL SPECIFICATION AND FEATURES • First car in india with rear engine and rear wheel drive. • Engine with 623cc • A 33bhp car • Having fuel efficiency 21.97km/ltr in city and 25.5km/ltr on highway. • First car with 2 cylinder non opposed petrol engine.

TECHNICAL SPECIFICATION AND FEATURES • • • • • Acceleration: 0-70 km/h in 14 seconds. Maximum speed: 105 km/h. Trunk capacity: 15 L. Front brake: disc Rear brake: drum

The Strategy • Tata divided the components into two types – proprietary designs and Tata Motors design. For proprietary design components. Tata went with established suppliers such as Bosch which supplies the engine management system and has significantly contributed to the future diesel engine.

The Strategy • For components and systems designed inhouse, Tata Motors chose suppliers with strong process capabilities who could give valuable suggestions and improve on the designs. Nearly everything has been sourced locally and the Nano will have 97% local content from day one. Tata’s suppliers were an integral part of not only the design and development process, but also purchasing.

Supplier Relation •E.Balasubramanian , head of sourcing for the project, was not a popular man with vendors and there were problem in order to get vendors to pare marging and persuade them to produce components at lower cost .

The vendors had to invest in new processes and methods to reengineer their products to specifications that were rigidly guided by cost , performance and regulatory compliances.

For example , P.K.Kataky , director of battery maker exide , was reported as saying that the company’s margin would be thin and it would start making money only after two or three years.

Getting suppliers ,who were mostly clustered in auto centres such as pune, chennai and delhi , to invest in singur , west bengal , which Tata motors had chosen for its small car plant , was difficult . “But now about 15-20 vendors would finish their plants along with Tata Motors”.

However A three-shift operation and consolidated purchasing with suppliers provided them with lots of relief.
