Transporting – the act of moving people, materials, or information from one place to another. In this series titled “The 8 Lean Wastes and Their Potentially Disastrous Effects”, we examine case studies for when companies, government organizations, or entire industries have allowed a specific type of waste to escalate to a disastrous effect. In this post, we review the waste of Transporting to understand what causes it, how to see it, and how to eliminate it.
The 8 Wastes and Their Potentially Disastrous Effects:
Based on data from the National EMS Information System (NEMSIS), the US national average time for an ambulance to arrive after an emergency call has been placed is 9.4 minutes. Just to level-set, the gold standard for ambulance arrival time is 8 minutes within 90% of the time. The data suggests that, on average, ambulances arrive 1.4 minutes late for an emergency call.
Additionally, the time to transport a patient back to the hospital to receive full treatment averaged 12.2 minutes in the dataset. This means that the time between the emergency call and the patient arriving at the hospital averaged almost 22 minutes in total.
The chances of surviving cardiac arrest diminishes greatly after 5 or 6 minutes of waiting time. How many deaths or serious complications could be prevented if we could design an emergency medical system with an overall response time of less than 5 minutes?

Transporting waste is abundant in just about any manufacturing or supply chain system. Since, for all practical purposes, multiple objects cannot occupy the same space at a time, transporting is an inevitable condition in the way we live, work, and play. One of the challenges to reducing transporting waste is that most methods of measuring productivity fail to highlight its existence. It’s important to measure delivery lead time from step to step within the factory and throughout the supply chain to help identify transporting waste; this also needs to be monitored on a continuous basis. Once you know to look for this type of waste, losses can fairly easily be measured and reduced in manufacturing or supply chain processes. For example, tools such as 5S, line layout, work cell design, and point-of-use supply (POUS) are all great approaches to minimize the waste of transporting within a factory.
The Factory Operating System (fOS) at factoryoperatingsystem.com also helps you see waste from transporting in the form of lost efficiency. In the fOS, this type of waste could either show up as downtime or rate losses. For example, if operators are having to travel across the factory to retrieve parts needed to perform a changeover, this entire time is captured under the planned downtime category. In this case, you might rearrange where items are being stored or staged in order to minimize transport time, changeovers, and efficiency losses due to planned downtime.
A manufacturing efficiency expert such as those at Manuficient can help you to improve the detection and elimination of transporting waste, resulting in significant cost savings and lead time reduction for your operation.
