I'm Mike Fox. I'm the Director of Group CIO in BT. BT is one of the world's largest providers of communications across the world and we operate in over 80 countries. We have a an enormous workforce that larger than 90,000 employees, 60,000 indirect employees. The debt we were carrying in our systems estate was holding us back and we also wanted to standardise our processes and also invest in a almost pressing the reset button on our systems. To create an agile platform. To grow and standardize across our different regions. The major benefit that we saw was the ability to standardize the way we did things. Examples we have right now is the speed at which we can deploy new processes, the speed at which we can standardize, the way we onboard, the standardization of large scale recruitment. And what the cloud did for us, it gave us the opportunity to invest in the more modern up-to-date technologies than we were actually using prior to this. And so we chose a transformational strategy that had us working really closely with the business on a new design, A fresh design. That allowed us to explore really the ways we could enable the business to be a bit more agile and to grow. So HR was not something that held the business back. I'm now thinking about a single service and a single platform. That reduces all the complexity, allows me to be less distracted by servers and storage. It's a lot more based on service. It's a lot more based on solutions. It allows us to make changes and enhancements to things like our performance management process. It means that we can absolutely revolutionize the way we do that in BT and we can do it quite easily, quite simply with configuration change. I think TCS, they know our business, they know our operating model and they know the complexities. They brought enormous amount of expertise to the problems that we were facing. They're able to fill the gaps that BT had when it came to looking at the technical challenges and also the business challenges as well. TCS helped us migrate from say 20 systems to a single system. They worked with us not only in the design and the build but they also helped to stabilise that system during the post call life period as well. So they brought an end to end partnership. To the programme. So in terms of reassuring me and working with TCS, I always found it extremely reassuring that they always had their commitment to fix problems with me to fix 1st and talk about it later. In terms of the attitude and the commitment of the account team, it was second to none. What I've seen previously in terms of the scale and complexity of the data migration work stream, working with TCS the risk that massively for me and it allowed me to be able to concentrate on other parts of the program knowing that work stream was in safe hands. What TCS bring to programs such as mine is deep knowledge of the business, a deep knowledge of the challenges and a deep knowledge of the risk. We work with TCS primarily because of the knowledge that they bring from a product perspective. From a business perspective, they bring great methods and the great tooling with them as well. I'd say TCS did have a significant input into the way the program worked. It wasn't as formulaic as people might want to expect it and to plan it. So you've always got to be flexible, you've always got to be agile and you've always got to be able to adapt to the problems within a programme of this size and scale. Think that what TCS brought was the certainty of their methods. They brought with them the certainty of the people, the ability to react and respond to challenges. They arose then absolutely. I think it's very important that the flexibility of the partnership is key to me. TCSR certainly part of my future plans and they work very closely. They bring so much knowledge of BT to my world and to my organization. We've been able to convert the way which BT manages the performance and monitors the performance of our organization. We've been able to totally standardise and simplify that. And in it's unrecognisable from two years ago to today, how we're actually working with our people and how we foster our talents.
