While serving as a Logistics Manager at an eCommerce company, our goal was to enhance our delivery times. I proposed leveraging GPS data from our delivery vehicles along with customer feedback to identify patterns and obstacles. By collecting and analyzing this data, I discovered critical areas for improvement, such as the impact of the day of the week, time of day, and specific traffic conditions on delivery speed. Armed with these insights, I decided to revise our delivery schedules and routes. As a result, within a few months, we achieved a 30% reduction in average delivery time, which greatly improved customer satisfaction. This experience highlighted the effectiveness of data in supporting informed decision-making.
