The Challenge at Hand

Imagine stepping into a Tata Motors showroom, exploring different models, and noticing a curious pattern—each car has a uniquely designed steering wheel. At first glance, it may seem like a minor detail, but what if standardizing these steering wheels could unlock massive cost savings and streamline production? This is the situation Tata Motors’ CEO faced after attending the Auto Expo in New Delhi, where a competitor, Maruti Suzuki, appeared to use a standardized steering wheel across multiple models. Now, Tata Motors must assess whether reducing the number of steering wheel variants is a feasible and profitable move.

 

1: Understanding the Context

Tata Motors currently uses eight different steering wheel designs across its car models. While these differences do not offer any real engineering advantage or customer differentiation, they add complexity to procurement, manufacturing, and logistics. With each steering wheel costing INR 800 and an annual purchase volume of 75,000 units per model, the total procurement cost reaches INR 480 crore per year.

The CEO has tasked us with evaluating whether standardizing to a single steering wheel model can reduce costs, improve efficiency, and simplify operations—without negatively impacting customer perception.

 

2: Identifying Key Questions

To determine the feasibility of steering wheel standardization, we must address the following:

  • Engineering Feasibility: Are there any constraints preventing a single steering wheel design across all Tata Motors vehicles?
  • Customer Perception: Do customers value steering wheel differentiation, or is it a negligible factor in purchase decisions?
  • Cost Implications: What are the potential savings from bulk procurement, and how would it impact Tata Motors’ bottom line?
  • Supply Chain Readiness: Can suppliers scale up production to meet the new demand efficiently?

 

 

3: Investigating the Root Cause of Cost Inefficiencies

To understand why Tata Motors' current approach is costly, we analyzed key operational and financial aspects:

  • Procurement Complexity: Managing eight different steering wheel models adds logistical overhead and limits the ability to negotiate volume discounts.
  • Manufacturing Inefficiencies: Different steering wheel designs require separate molds, assembly lines, and inventory tracking, increasing production costs.
  • Missed Economies of Scale: Standardization can lead to supplier discounts, reduced warehousing needs, and optimized production lines.

 

4: Evaluating Cost Savings and Operational Efficiencies

By shifting to a single steering wheel model, Tata Motors can unlock significant financial benefits:

  • Bulk Purchase Discounts: Suppliers offer a 5% discount for every doubling of order quantity and a 20% discount for complete standardization.
  • Projected Cost Savings:
    • Current Cost: 8 models × 75,000 units × INR 800 = INR 480 crore annually.
    • Post-Standardization Cost: 600,000 units × INR 640 (after 20% discount) = INR 384 crore.
    • Total Savings: INR 96 crore annually (~20% reduction).

Additional operational benefits include:

  • Simplified Logistics & Warehousing: Reduced inventory complexity leads to streamlined supply chain management.
  • Faster Production Cycles: Standardization enables assembly line efficiency and lower downtime in manufacturing plants.

 

5: Mitigating Risks & Addressing Challenges

Before implementing this strategy, Tata Motors must address potential risks:

  • Supply Chain Constraints: Ensuring that suppliers can scale up production to meet increased demand.
  • Consumer Perception Risks: While customers do not actively choose cars based on steering wheel design, the brand must reinforce messaging that standardization enhances quality and efficiency.
  • Transition Costs: Initial retooling costs and possible disruptions during the transition phase must be planned for.

 

6: Strategic Recommendations & Next Steps

Given the compelling cost savings and operational efficiencies, Tata Motors should proceed with steering wheel standardization. To ensure a smooth transition, the company should:

  • Engage with Suppliers: Confirm supplier capacity to produce 600,000 standardized units annually and negotiate volume discounts.
  • Conduct a Pilot Rollout: Test standardization on select models before full-scale implementation.
  • Enhance Brand Messaging: Position the change as a move toward efficiency and affordability rather than a reduction in product differentiation.
  • Explore Further Standardization Opportunities: Assess similar cost-saving measures in other components like dashboards and headlights.

By implementing these steps, Tata Motors can unlock substantial cost savings while improving production efficiency—setting the stage for broader manufacturing optimizations in the future.
