"An international electronics company with multiple product lines is planning to implement a Just-In-Time (JIT) inventory system to reduce inventory holding costs. However, the suppliers are located in different countries, and the company is concerned about lead time variability due to geopolitical uncertainties and logistics issues. Considering the bullwhip effect, how can the company effectively implement a JIT system while minimizing the risks associated with lead time variability and ensuring a consistent flow of materials for production? Evaluate potential strategies, such as supplier diversification, safety stock management, information sharing, and lead time reduction, and recommend an approach that balances cost, risk, and responsiveness."

This question is difficult because it combines several elements of Operations Management, including JIT inventory systems, supply chain risks, and the bullwhip effect.
