AT&T's Stine: Driving the Data That Fuels Business Success

How data gets used
Perhaps the best way to look at the data organization's work is through the lens of specific use cases. While working on his hyper-automation assignment from Donovan, for example, Stine and his team explored how to optimize AT&T's truck dispatch operation. The company's 70,000 trucks traverse various geographies for diverse reasons -- installations and repairs being the main two -- in all kinds of weather and traffic conditions. Routing those vehicles more efficiently not only saves money by increasing productivity but directly impacts the customer experience as well. For example, instead of annoying new customers by asking them to set aside a day or half-day for a service turn-up, AT&T might be able to more precisely define when its crew would arrive, down to 15-minute segments.

"Just small increments of productivity means more jobs per individual per day and that improves the customer experience, but it also certainly helps the business in total from a resource and capacity planning standpoint," he said.

But the factors that must be taken into account for this to happen are many and changeable: weather, traffic, the specific facilities and task involved, the technician's training, the available truck and how it is equipped, as well as past performance. There is no way for a human dispatch capability to collect all of that data in real-time, repeatedly throughout a day, and keep up, producing the kind of productivity results AT&T wants, Stine says.

"We started to look at, how do you take an optimization engine, think machine learning, and start to bring all those things together, so all day long while you have a to-do list that's in queue to line up for dispatch, how are you always ensuring that you're updating that, so best tech, best customer experience, all of those things are accounted for in real-time?" he comments.

As AT&T is assembling this data, machine learning is also built in so that lessons learned in a given week's dispatches are applied to the operation immediately to impact the next week's processes.

The network operator is also working to aggregate all the data involved in network incidents - whether those are fiber cuts, equipment issues, malicious attacks causing congestion, or something else, Stine says. On AT&T's global network incidents occur regularly and potentially impact customers, but also internal elements such as radio towers, backhaul networks and video equipment, he adds. Information about any given incident will go into customer care centers for businesses or consumers, but also into other network operations centers. Customer calls may also be coming into the care centers.

"We said, 'Let's aggregate all this data'," Stine says. "In real time, this might take several hours for everybody to come together and coalesce around what it is specifically, thus who should we send to repair that cut fiber. We can now do this in nanoseconds."

That means in the instance of a fiber cut, for example, trucks can be rolled faster from the construction organization and the right truck can be sent the first time, while messages to all affected parties are also sent out immediately with accurate information regarding restoration times, he says. Customers can be proactively contacted and, when possible, services can be protected from impact.

AT&T was already doing a lot of this, using some automation, but without the data aggregation piece, he says. "There was no aggregation of the data with the intent of even, when I found out what it was, of saying every time I see a like signature to this, what should we do, and how should we react in order to really start to narrow impacts to customers or eliminate impact to customers if possible from these activities that go on," Stine comments.

The data organization also has the ability to continue to better inform how software-defined networking is used to improve network self-optimization that already happens today, to keep capacity available and maintain performance. "We know that every day we've got an opportunity to learn more," Stine says. With more data, comes more information and AT&T has a policy under its head of technology and operations Melissa Arnoldi of "relentlessly sharing what we're all doing to make sure that the broader benefit is received throughout the business."

That tight integration extends to working with the Chief Security Officer Bill O'Hern's organization to ensure data security as well as with AT&T's privacy organization, to ensure privacy and security of data, in motion and in storage, is built in from the outset and carefully maintained. Stine also says there is strategic importance in knowing when not to keep data -- especially if it isn't needed for compliance reasons -- since keeping data around incurs cost and also increases potential vulnerabilities.

Analyzing data By analyzing data a business can get a lot of insights to make a comprehensive SWOT-analysis, but also to understand their target audiences and remaining stakeholders.

The key in my opinion is to understand HOW to use and manage the big pile of data. By not knowing where to start working with the data, one can easily be victim of confusion.
