CHAPTER 9
IMPLEMENTATION OF JUST-IN-TIME(JIT) CONCEPT IN INDIAN INDUSTRIES
9.1 INTRODUCTION:
Just-in-Time (JIT) is one of the most sophisticated techniques which has wide reach¬
ing applications. This technique is widely implemented in
abroad. Until now the JIT ideal was just limited to the Western advanced coun¬
tries and Japan. But due to technical advancement and globalisation, today India
is also implementing this concept in various industries moving gradually from the
traditional inventory methods.
The word Just-in-Time (JIT) is synonymous with Toyota Production System
(TPS). After the successful implementation of JIT at Toyota, other industries in
the Western World implemented the concept of JIT. The onslought was more in the
automobile industries.
The case studies of the industries that have completely implemented JIT concepts
features of JIT to reduce the overall cost have been
presented in this chapter. A tabular form below represents brief summary of some

9.2 IMPLEMENTATION OF JIT IN BAJAJ AUTO LTD.
We discuss here the case study of Bajan Auto Ltd. who has fully implemented JIT
by using the concept of ABC/ Analysis.
Auto slotted its suppliers into three categories and applied different ptir-Bajaj

lead of between 10 and 15 percent over its competitors in the manufacture of its 2-

The company had divided its 3,000 - and-odd components that go into
A’, ‘B’ and ‘C\ The first consisted of high value
(Rs.1000 and above) items; the second, medium value (between Rs.500 and Rs.1000);
and the third, low value (below Rs.500). This classification helped the managers to

scooters into three categories -

build inventories in inverse proportion to the average cost of each genere. Thus inven¬
tories for ‘A‘-class items are never more than for one shift. Even then the company
did not run out of stock. This was only because of JIT. The orders were placed every
week and the daily deliveries were made. In order to ensure that the inventory-level is
kept at minimum, Bajaj Auto got rid of quality inspection of these products. Instead
it became mandatory for vendors to conform to its self-certification programme under
which they guarantee the quality of their output and feed their supplies directly
the production line. 174 out of 1000 of its vendors fell in this category. Bajaj saved

Kanban process. Under the Kanban system, the requirements for the production line
for a particular component are indicated visually through cards which the suppliers
use to deliver exactly as much as is required.
This was not enough just to cut down the costs. This would result in forcing the
suppliers to hold more inventories. Thus the vendors push away from the company.
Bajan Auto, hence communicates its tentative production-plan 3-mont.hs ahead ol
schedule, the semi-final is relayed to them 45-days ahead, and the final production
scheduel is frozen to 30 days in advance.
The overall impact of these strategies was that the average inventories had fallen
from 30 days in 1994 to 12 days today.
CASE STUDY OF ASHOK LEYLAND WHICH IM¬
PLEMENTED JIT9.3
Ashok Leyland, another leading automobile industry in India, implemented JI T and
reached the targets of reduced inventory control and high level of productivity. Al¬
most 18 months ago. Ashok Leyland had to allow tower inventories helplessly. The
company’s profits had crashed from Its.124.93 crores to a meagre Its.18.-11 crores.
The company was fighting for its survival.
Then began Project OSCARS which stands for Optimising Supply Chain and
Rationalising Sourcing - aimed at vendor selection and development, better planning
and scheduling, and inventory control process. Until then the company was main¬
taining inventories worth 45 days, in comparison to 3 lo 5 days globally. This was
because the components were ordered by Ashok Leyland on the basis of an annual
production schedule which was going haywire.
155
1 (169)
Under the Project Oscar, the 5000-and-odd components which the company used
were categorised into ‘A!, ‘B’ and ‘C!. A items amounted to 75 percent of the total
cost of components, ‘B! items, 18 percent and ‘C’ items, 7 percent. Based on this
the company devised different delivery systems for each category, aimed at cutting
inventory holdings. For the supply of ‘A class items, a JIT system was utilized. Under
this the plant sent a JIT card, specifying the part number, quantity and the unloading
location to the supplier, who promptly despatched the required consignment directly
to the assembly line. Project OSCAll devised a funnel-planning system, covering ()
weeks of requirements. The broadest part- stands for the tentative requirement of the 1
last two weeks out of the six (6). The middle part of the semifrozen requirement for
the middle 2 weeks and the narrowest, part and the frozen requirement for the first two
weeks. So the vendor knows roughly when to expect the JIT card. Simultaneously,
Project OSCARs started a pull-based system on Ashok LeyIand shopfloor, where
each stage produces only as much as the next stage needs. The ultimate result of
adopting JIT was high productivity and a lean supply chain. The company thus save
Rs.8.50 crores a year. There are many more companies which used JIT and other
related techniques like Business Process Re-engineering (BPR) to achieve the major
targets like elimination of waste, reduction in lead time, high level of flexibility etc.
Also one of the major factors that make JIT superior to the traditional techniques is
the geographical proximity of the single source of supply which is utilized by many
companies.
The case studies of some of the industries that implemented JIT and other related
ideals partially, in order to achieve the above mentioned factors are discussed below:

Thus the company’s most out sourced raw material - electron guns and deflection

9.5 WIPRO ACHIEVED REDUCTION IN INVENTORIESBY STICKING TO SINGLE SOURCE OF SUPPLY
Similarly, Wipro Corporation also achieved remarkable results by implementing JIT,
firstly, the dot-matrix printer division reduced its procurement costs by 50% by
curtailing its vendor base from 140 to TO and focussing on single source of supply as
much as possible. Also the unit developed its suppliers within a 50 km radius. HenceV
company’s inventories shrunk from 15 days in 1992 to 3 days in 1998.the
9.6 SUNDARAM BRAKE LININGS USED THE VENDORBUYER RELATIONSHIP TO REDUCE COSTS
Sundaram Brake Linings (SBL) used the heart of supply chain management - the
supplier-vendor relationship. The closer and more dependent they
the better is the outcome. SBL used the principle of single sourcing to slice through
its bills for asbestos. Initially it bought from three different suppliers. This resultedin increased transaction costs. So they changed their tact and developed a structured
sourcing system with John Manville Co. (JMC) of Canada. Now SBL provides
JMC with a 12-week requirement schedule which the latter meets by delivering every
Monday. Thus SBL saves on inventory pile-ups and enjoys the flexibility of changing
the combination of different kinds of asbestos upto 3 weeks before each shipment.
This would have been impossible and SBL negotiated with multiple sources of supply.
Looking at the vendor’s ability to match with its schedule, SBL ordered asbestos on
a need-determined basis thus cutting costs significantly.

9.7 CARD-SIGNALLING SYSTEM USED BY RANEMADRAS
Ilane Madras is a steering gear manufacturing company where cellular lines riot only
increased throughout time, but also reduced the cycle time. At the core of it, they
used the card signalling system of Kanban and just-in-time inventory management.
To minimise, work-in-progress Rane employed a card signalling system. Every stage
in the process is an internal customer and parts are supplied only against demand.
However a minimum is maintained to prevent the stoppage of the line in case there

will have a system where its nearby vendors will produce as per a Kanban coming
from Rane’s shopfloor. The ultimate result of the implementation of JIT i

JI1, Escort reduced the cost per tractor by 20 per cent. Rear Axle unit targeted a
cost reduction of Rs.84.80 per unit. Willi the current output of 20,000 rear axles, it
amounts to a cut of Rs.lG.96 lakh(i) 72.6 percent increase in productivity, (ii) increase in capacity by 12,868 tractors,

9.9 JINDAL VIJAYANAGAR STEEL
File company began the production of hot rolled and cold rolled steel colls at its new
plant. Then, the company took the responsibility of supplying at the time and place
specified by the buyer - on a JIT basis. The company uses a fleet of 50 hired Volvo
trucks, each of which has a capacity of carrying 60 tonnes. The trucks are run round
the clock, with drivers relieving one another every 8 hours, on different routes. This
enables shortest permissible delays.
The company estimates show that the travel time have slashed down drastically.
The travel Lime has been reduced by 50 percent.
