Ultron, an Indian white goods manufacturer, was struggling to manage warehouse inventory during the busiest season of the year. The company had a growing portfolio of products in the warehouse and inventory that was more than 180 days old. The main reason for the dated inventory was the absence of a warehouse management system, which meant that inventory was tracked manually and the company, hence, was unable to maintain a first-in, first-out (FIFO) sequence of the products in the warehouse. Given the substantial investment costs associated with installing warehouse management software, the company was evaluating other alternatives for implementing FIFO at the manually operated warehouse. Analyze the case carefully and determine what is the best option for the company to overcome the FIFO problem in the warehouse. Can the aisle configuration in the warehouse be changed to achieve better picking efficiency? What are the alternatives for attaining FIFO in the warehouse without investment in a warehouse management system? Please note the following : 1. Please mention the reference sources used.
