Q.5 Indian institute of material management (IIMM) is a forum for purchase and materials
related employees and they have frequent meetings, seminars and annual conventions to
share knowledge.
In one of their annual conventions the topic was implementation of JIT for competitive
Page 3 of 3
advantage. Leading personalities of the IIMM talked lots of positive and benefits due to
the JIT manufacturing systems. However few of the executive participants were more
worried about practice and less interested in idealistic theories.
One Mr. Jitendra Joshi of LML's Bangalore office was impressed. He has been
arranging engine block castings, tyre tube sets, machined components, speedometers etc
from southern region of LML, Kanpur unit. He has 15 years of experience in facing lots
of problems in arranging the long distance supplies. He mustered courage to get and ask
few questions against the JIT and summary of question to Mr. Sudhakar the speaker)
were as follows:
Mr. Joshi said JIT cannot be fully implement able in Indian conditions due to the
following genuine constraints:
The inter-state disputes like 'Kaveri Dispute', 'Border Disputes' at times disturb
the arrangements.
On and off terrorism, political agitations, holidays due to local, regional and
national leaders' deaths also disturb work environment.
Spread of vendors all over India and vastness of coverage do not enable to know
correct position of WIP of vendors.
Transport bottlenecks, heavy rain, floods (coastal areas), workers' strikes cause
anxiety and worry.
Partnership problems, financial and quality constraints are not easily attended or
solved.
These questions were like a mini speech on anti JIT and the atmosphere in the
auditorium got changed up Mr. Sudhakar, the speaker, gave half hearted replies to
questions for which Mr. Joshi and his friends were not satisfied. Finally Mr. Sudhakar
said:
"The system which operate successfully in Japan may not work equally well in other
countries". Only when Mr. Joshi took his seat as he felt he has made his clean on
practical problems than merely going through the theory. Suddenly he seems to have
won the admiration of the gathering.
Prof. Rao who was chairman of the technical session gave his concluding remarks. He
appreciated the ideology of JIT but advised executives to take it up step by step and
ensure pragmatic views and do not over depend on JIT to fail. This he told as Indian
industrial environment is yet to mature to take care of JIT system in totality.
