Harvard Case - Larsen and Toubro: Spare Parts Forecasting
"Larsen and Toubro: Spare Parts Forecasting" Harvard business case study is written by Suhruta Kulkarni, Prakash Hegde, Ruchi Jaiswal, Dinesh Kumar Unnikrishnan. It deals with the challenges in the field of Operations Management. The case study is 11 page(s) long and it was first published on : Jan 30, 2015
At Fern Fort University, we recommend Larsen & Toubro (L&T) implement a comprehensive spare parts forecasting and inventory management system that leverages advanced analytics, integrates with existing ERP systems, and optimizes supply chain operations for improved customer satisfaction, reduced inventory costs, and enhanced operational efficiency.
2. Background
L&T, a leading Indian multinational conglomerate, faces the challenge of managing a vast and complex spare parts inventory for its diverse range of products and services. The case study highlights the difficulties in accurately forecasting demand for spare parts, leading to stockouts, excessive inventory, and inefficiencies in the supply chain. This situation negatively impacts customer satisfaction, operational costs, and overall profitability.
The main protagonists in this case are the L&T management team responsible for improving spare parts forecasting and inventory management. They are tasked with finding a solution that addresses the existing issues and optimizes operations.
3. Analysis of the Case Study
This case study can be analyzed using a framework that combines operations strategy, supply chain management, and technology and analytics.
Operations Strategy: L&T's current operations strategy for spare parts management is reactive and inefficient. The lack of accurate forecasting leads to inconsistent inventory levels, impacting customer service and operational costs.
Supply Chain Management: L&T's supply chain for spare parts is characterized by inefficiencies, including:
- Poor demand forecasting: Leading to stockouts and excess inventory.
- Lack of centralized inventory management: Resulting in duplication and difficulty in tracking inventory levels.
- Limited visibility into the supply chain: Making it difficult to identify bottlenecks and optimize flow.
Technology and Analytics: L&T can leverage technology and analytics to improve its spare parts forecasting and inventory management. This includes:
- Advanced forecasting models: Incorporating historical data, market trends, and external factors to generate more accurate predictions.
- Real-time inventory tracking: Providing visibility into stock levels and enabling better decision-making.
- Data analytics: Identifying patterns and trends in spare parts demand to optimize inventory levels and improve forecasting accuracy.
4. Recommendations
To address the challenges faced by L&T, we recommend the following:
Implement a robust forecasting system: This system should leverage advanced statistical models, incorporating historical data, market trends, product lifecycle information, and external factors. The system should be integrated with L&T's existing ERP system for seamless data flow and real-time updates.
Centralize inventory management: Establish a centralized inventory management system to track spare parts across all locations, providing real-time visibility into stock levels and demand patterns. This system should be integrated with the forecasting system to ensure optimal inventory levels and minimize stockouts.
Optimize supply chain operations: Analyze the existing supply chain for bottlenecks and inefficiencies. Implement lean manufacturing principles, such as Just-in-Time (JIT) production, to reduce lead times and optimize inventory levels.
Leverage technology and analytics: Implement advanced analytics tools to identify patterns and trends in spare parts demand, improve forecasting accuracy, and optimize inventory levels. Utilize data visualization dashboards to provide clear insights into key performance indicators (KPIs) for inventory management.
Implement a robust risk management framework: Identify potential risks associated with spare parts forecasting and inventory management, including supply chain disruptions, product obsolescence, and demand fluctuations. Develop contingency plans to mitigate these risks and ensure business continuity.
5. Basis of Recommendations
These recommendations are based on the following considerations:
Core competencies and consistency with mission: Improving spare parts forecasting and inventory management aligns with L&T's mission to provide high-quality products and services while optimizing operational efficiency.
External customers and internal clients: The recommendations aim to improve customer satisfaction by reducing stockouts and ensuring timely delivery of spare parts. They also benefit internal clients by streamlining operations and reducing the burden on inventory management teams.
Competitors: Implementing advanced forecasting and inventory management systems can give L&T a competitive advantage by enabling faster response times, lower costs, and improved customer service.
Attractiveness ' quantitative measures: The proposed solutions are expected to result in significant cost savings through reduced inventory holding costs, improved efficiency, and minimized stockouts. This can be measured through KPIs such as inventory turnover, fill rate, and cost of goods sold.
6. Conclusion
By implementing these recommendations, L&T can significantly improve its spare parts forecasting and inventory management, leading to increased customer satisfaction, reduced costs, and enhanced operational efficiency. The use of advanced technology and analytics will enable L&T to make data-driven decisions, optimize supply chain operations, and maintain a competitive edge in the market.
7. Discussion
Other alternatives not selected include:
- Outsourcing spare parts management: This could be a viable option for L&T, but it requires careful consideration of cost, control, and potential risks associated with outsourcing.
- Adopting a traditional forecasting model: While this may be less expensive than implementing advanced analytics, it is likely to result in less accurate forecasting and higher inventory costs.
Key assumptions of our recommendations include:
- L&T has access to sufficient historical data for accurate forecasting.
- L&T is willing to invest in technology and training to implement the recommended solutions.
- The proposed solutions will be successfully integrated with L&T's existing systems.
8. Next Steps
To implement these recommendations, L&T should follow these steps:
- Form a project team: Assemble a cross-functional team with expertise in operations, supply chain management, technology, and analytics.
- Conduct a thorough analysis of the existing spare parts forecasting and inventory management processes.
- Develop a detailed implementation plan: This plan should include timelines, milestones, and resource allocation.
- Select and implement the appropriate forecasting and inventory management software.
- Train employees on the new systems and processes.
- Monitor and evaluate the performance of the new system: Use KPIs to track progress and make adjustments as needed.
By taking these steps, L&T can successfully implement a comprehensive spare parts forecasting and inventory management system that will lead to significant improvements in operational efficiency, customer satisfaction, and profitability.

Case Description
Larsen and Toubro (L&T) was India's largest technology, engineering, construction and manufacturing company. Construction and Mining Business (CMB) sold equipment such as Dozer Shovels, Dozers, Dumpers, Hydraulic Excavators, Motor Graders, Pipe Layers, Surface Miners, Tipper Trucks, Wheel Dozers and Wheel Loaders. CMB also provided the services of equipment installation and commissioning and other maintenance services. Supply of spare parts was critical, since the customer faced severe losses in case of equipment unavailability. Forecasting was done on an ad hoc basis based on the experience of the planning personnel. The value of each spare part ranged from INR 10 to INR 8 Million. It was critical to maintain a correct balance for the spare-parts inventories, since unavailability led to loss of revenues, decreased profitability, customer dissatisfaction and also gave rise to the fake products industry. Excess inventory led to high inventory carrying costs, working capital lock-in and also a possibility of spare parts becoming obsolete. Vijaya Kumar, Deputy General Manager of CMB, had to arrive at a forecasting methodology with an error of less than 10% for the 20,000 odd spare-parts. This warranted for 20,000 forecasting models, however this was not only very time consuming but also very expensive to develop and manage. Kumar wanted to build the forecasting model quickly so that he could roll out the forecasting strategy on a pan-India basis within a few weeks.
