TalkTalk Case Study

Modern Workplace with Microsoft 365

Media and telco giant, TalkTalk, has over 4.5M customers, but outdated tools meant that for many of the employees, ten miles apart in geography seemed like 100 miles apart from our customers.

Standing on top of a mountain during the arduous ‘3 Peaks Challenge’, a TalkTalk employee commented on how great it would be to update colleagues on their progress; unfortunately, they didn’t have the capability to do so. Today, they do; after a partnership with Cognizant Microsoft Business Group, they have elevated their workplace to match their progressive and dynamic employees, enabling and empowering them to work smarter from any location.


TalkTalk, a market leading telecommunications business, is renowned for its dynamic and progressive culture where small teams work closely together. But as tools started to slow down collaboration, employees were attempting to find solutions for themselves. Mounting IT costs, system complexity and challenges with secure remote collaboration were becoming rife. TalkTalk wanted a radical reform of their working environment, to centralise all teams in one office and to create an environment that promoted mobile productivity.


Cognizant MBG worked with TalkTalk to define a new Modern Workplace solution based on Microsoft 365, which kept the user firmly at the centre of the transformation. Today the business is empowered for flexible and agile working, multi-device communication, centralised tools for internal and external collaboration and secure environments to access documents from any location or device.


“It’s been incredibly successful. Cognizant Microsoft Business Group brought real value through the change process, really driving the user perspective. We’ve built a solid relationship for future projects.” John Gaskell, Office 365 Lead Architect - TalkTalk


Cognizant MBG migrated 2.5k users into the new environment over five days without a single incident. Since the migration, email volume has reduced dramatically, as Skype for Business becomes the communications tool of choice. Internal service desk calls have also dropped by around 600-700 calls a month (over 30%) thanks to the intuitive nature of the cloud services and the IT team are liberated to work on areas which drive value to the business. Reduced downtime, redundant point applications and greater operational efficiency are all contributing to impressive cost savings.
