Namratha Oil Refineries Pvt. Ltd.: Tackling Oil Giveaway
內容大綱
In March 2017, the director of operations at Namratha Oil Refineries Pvt. Ltd., a leading manufacturer and distributor of high-quality packaged coconut oil in southwest India, faced a challenge. Because of inefficiencies in the company’s packaging division, pouches, jars, and bottles were being overfilled with coconut oil, leading to an “oil giveaway” that had weakened the company’s bottom line. The director analyzed the current processes and discovered improper data recording, frequent breakdowns, poor allocation of the maintenance crew, and an improper inventory management system. His experience told him that the existing production facilities were sufficient to meet the company’s requirements, and therefore, the existing processes needed to be streamlined to ensure minimal or no loss of oil. What strategy should he recommend to reduce losses and restore the company’s profitability?
