The context

• Jamshedpur : a manufacturing hub• Tata steel + Tata Motors- perfect location• Logistically well connected• Still poor efficiency in demand fulfillment

The problem

• Erratic behaviour of supply chain of Tata motors, and tracking of per vehicle consumption of critical grades of steel .

Research Design

• Primary data• Secondary Data• Qualitative design• Questionaire design• Data collection

Procedural steps :

• Understanding the manufacturing process flow at Tata Steel.• Understanding the manufacturing process flow Tata Motors.• Analyzing the demand demographics of Tata Motors• Identifying the role of TSPDL.• Conducting vendor visits and interaction• Data collection and analysis• Result generation

A bit about steel

• HR : Hot rolled - thickness of 2- 10 mm - poor surface finish - good mechanical strength• CR : Cold rolled - Thickness of 0.75 mm to 2 mm - good surface finish - not so good mechanical strength

The supply chain flow

TATA STEEL • VENDORSTSPDL

TATA MOTORS

Plan of study

• Study has ben planned in two phases 1) evaluation of the perception of tata steel among tata motors ancillaries and evaluation of problems 2) Evaluating the steel consumption per grade per vehicle, so as to facilitate better understanding of the consumption pattern

The Findings : Vendors satisfaction

Conclusion

• Demand supply gap for critical grades• Vendors wrongly influence demand• Scheduling on both fronts is defective• No adherence to the safety stock policy• No information management system for ancillaries• Unethical logistical practices

Recmmendations

• Reduce lead time for critical grades• Adopt appropriate sizing of finished coils.• Implementation of state of the art information system• The supply line should be properly maintained.• They should improve customer relationship.• Ensuring greater schedule accuracy• If possible engage the vendors directly• Investing in safety stock inventory storage capacity
