T-Mobile touts itself as “America’s Fastest Unlimited Network.”

In a fiercely competitive market, T-Mobile knows one of its most crucial responsibilities is to bring pleasurable customer support to the millions who call their helpline each month. While traditionally its call service center resembled a factory floor (cubicles brimming with reps donning headsets), T-Mobile has dedicated the past decade to reinventing its service sector.

Today when you enter a T-Mobile contact center, you’ll find reps sitting together in shared pods as they collaborate to solve customer issues as a “Team of Experts,” or TEX. TEX teams include cross-functional groups of 47 people who serve named customer accounts in a specific market. Each team has a point leader, four coaches, and eight technology specialists. Customers no longer wade through a “call tree” but have immediate access to a dedicated, reliable team. Teams are so connected to their service region that they follow the daily news in this area and decorate their pods accordingly (like a Lego replica of the Golden Gate bridge).

“We’re constantly talking about what’s happening there,” said a senior rep whose team serves San Diego. “I’ve never been to San Diego, but I know what’s going on in the local news, where the best place is for fish tacos, and what the surf report looks like for the next few days.”

Now a team in Chattanooga is responsible for 120,000 customers in Detroit, and a Charleston team responds to suburban Philadelphia. This collaboration allows each service team to operate like a small business, with members laboring together to increase performance. As a result, employee turnover has decreased by 48%. T-Mobile now boasts its lowest “cost to serve” ratio in company history (down 13% since 2016) and has been ranked the number one wireless company for service by Nielsen for the past 24 months.

Together Everyone Achieves More

Team collaboration fuels innovation and provides consistent service for your customers.

Does your team have a sense of enthusiasm or shared DNA that brings measurable results? T-Mobile started with four questions:

• Are our customers happier?
• Are they staying with us longer?
• Are we deepening our relationship with them?
• Are we making their service experience low-effort?

Embracing a team-service focus brings your clients more effective answers. Reps develop more authentic relationships with clients, which means they can improve their everyday service functions. And this ultimately enhances the product or service you offer. A superior output prompts higher customer loyalty, increased sales, and better word-of-mouth for your business.

Here are three tips to help you improve customer service teamwork:

Clearly State the Team Objectives

Teams can’t move fluidly until everyone knows what the “win” is.

Highlight Team Performance

Regularly communicate achievements, challenges, and specific goals. As progress is celebrated, motivation and unity increases.

Create a Sense of Belonging

While T-Mobile’s traditional customer-service managers only measured individual performance, today compensation is variably weighted according to both individual and team performance.

Teams use collaboration software to resolve calls and alert each other of escalating issues (like regional power outages). From this ownership mindset to a wholesale transformation of the factory floor, customer care vice president Callie Field says team unity has empowered everyone to do more:

“If all you ask people to do is bring down their handle time, they can do that. But if you empower them to do more—to think like a small-business owner who is focused on the customer’s happiness and the strategic management of their P&L—they can do that too. And they’ll do it really well if you give them the tools and get out of their way.”
