Telefonica has appointed NTT Data to help transform its quality assurance and testing services (QAT).

The three-year contract is hoped to improve testing efficiency as well as operational capabilities, enabling the firm behind O2 to keep up with customer feedback when a new product is rolled out.

The mobile operator claims the agreement means its customers will benefit from a quicker time to get to market, as well as continual investments in quality testing leading to better products.

Telefonica’s head of service experience, Colin Cunningham, said: "The quality assurance teams are the guardians of the great customer experience we strive for, and so are an essential part of the process.

"Our aim is to keep our customers and their businesses connected 24 hours a day, seven days a week, 365 days a year. Strong QAT helps iron out any potential problems and reduces any downtime experienced by customers."

NTT Data will initially test productsa in Telefonica’s IT and network departments, before gradually expanding to test products in all areas.
