 Supply chain management is like a symphony. Each of the players needs to play the right instrument at the right time. Even if one of them slips, the whole system can collapse. Let's imagine that there's a pharmaceutical company that has some products stuck in transit at a port. Whenever there's a disruption, everybody is running around. They're trying to put out that fire as soon as possible. The more information we've got about what is the status on the ground helps us optimize better. Every firm should try to get end-to-end visibility around its products. Our customers really just want to track products that they're sending out to customers, raw materials that are coming into their manufacturing plants. They need to know where it is and when it's going to arrive. Resiliency is how quickly can your supply chain come back to normal level of operations when it faces some kind of a disruption or crisis. Technology plays a very important role in bridging the gap between what might be in the system and what is in real life. There are many asset-tracking technologies that are out there. Most of those are used indoors, not necessarily in the supply chain because they require the proximity of a reader or a gateway to read the tag. Once it leaves a distribution facility, you no longer have visibility. So AT&T offers cellular-based and satellite-based asset trackers that provide near real-time visibility and that data that can be sent back to the customer. This can allow customers to pivot and react. That data is what can increase the resiliency of a customer's supply chain. Pharmaceutical firms are what we call as cold supply chains. We've got to worry about the temperature at those containers. Are we maintaining those limits that we have? And if you are deviating, we need to know exactly where we are deviating. In some cases, the whole drug might have deteriorated and should not be given to the patient. With the additional data that we can collect using these devices, we have machine learning and artificial intelligence solutions that can predict late arrivals, determine whether temperature ranges are being compromised. They can send data and alerts to the customer in near real-time. The name of the game today is how you use information within the context of supply chain. And so it's extremely important to have a great connectivity partner. There are a few areas that AT&T business is working on that will greatly enhance the visibility throughout supply chain. This is all cutting edge. One is precise positioning, which is going to make the location that's provided from these asset trackers more accurate. This actually provides correction of some of that data based on earth movement, based on weather and other things pretty slick.
