(upbeat instrumental pop music) - [David] DWP itself is the largest government department. It has around about 90,000 employees. We look after actively 25 million citizens and round about 200 billion pounds worth of taxpayer's money flows through the department every year. - [James] where we were before, we had quite old, heavy, slow Windows 7 laptops for our mobile users and we started a small proof of concept, probably about three years ago now, to look at more modern, light, faster Windows 10 based devices. - The response we got from our employees, our colleagues, when we introduced the Surface Pros was phenomenal. It was an absolute step change from where they were before. - Speed of the devices, the weight of the devices, the flexibility the devices allowed them to do their daily tasks. And so that rapidly expanded, we purchased a significant number of what were Surface Pro 4s and then 5s and then 6s over a number of years. The move to cloud services is less of a reliance on expensive and hard to maintain on premise hosting, and the ability to scale really quickly. - What I'm looking for is a device that is truly, truly cloud native. One which never comes home, one which lives out in the big, bad world, which can be configured remotely, which you take out the box and it just works. - Security within DWP is a key element because we deal with customers' data and we want to make sure that data is secured, not only when it's in transit, but also when the data - - [David] Cloud-first allows us to really simplify the build and deployment stages. What autopilot allows us to do, send it directly to that individual, when that individual takes it out of the box, that machine builds. And then it builds on the individual's applications on top of that, so from opening it in the box very, very quickly over the air, anywhere that machine knows what it is, who it belongs to and how it needs to build. - They don't have to worry about going to this device or that device, they can just open it up really quickly, look at the device with Windows hello, log into that device and get the softwares up and running that they need for that day. - Element of our ability to be successful in such a short period of time is our collaboration with Microsoft. - One of the most impressive things through this project has been the relationship between Microsoft and DWP. They've worked fantastically together and we've achieved a lot.
