Coventry Society was founded in 1881 and we're now the second largest building society in the UK. Last year we lent 10 billion in completions and have a book of 47 billion in terms of employees. We're now employed 2600 people in our head office and branches around the country and be very much badly diversity and inclusion. When it came to mortgages, we've got a legacy long standing mortgage platform that had served us really well over multiple decades. How it was clear that it hadn't really got the scale that required for the future growth of the organization. Our ability to sort of react to where the market was going was slow as a result of that and the type of technology that had been built on really wasn't sort of fit for purpose then we needed to make sure that we had a system that allow us to secure, acquire, process, and manage a much bigger mortgage book. With the challenges we had with our IT infrastructure, our legacy systems, a lot of manual processes and their resilience over overarching all of that, it became very, very clear that we had to do something and find a partner that could help us do that quickly. The partnership with the Coventry Building Society started in 2019 with a consulting study to improve the effectiveness of their cells and origination process. And while the focus of the study was technology elements, we did bring in a lot of business outcomes. Our approach to bring in  the growth and transformation in the business outcomes was appreciated very much and our knowledge about the mortgage industry in the UK and the building societies were very effective in this journey.We need an organization that understood the technology we're bringing into the organization. But also an organization that will be able to make sure that what we built was something that was fit for the future, so a sustainable technology platform. TCS absolutely delivered that for us. I think one of the big call outs we would say was Web chat is something that we'd always talked about but never actually delivered. The pandemic gave us a real opportunity because there was demand from our broker partners to want to interact with us via a digital channel. And I think what TCS ports of this was a really good way of working, very disciplined, hard working. And looking for initiative ways to help us deliver this broker engagement on this when they use the web chat once it was launched was over 90% and on average now we take about 400 chats a day with a peak of 900. There were many milestones in this program. We posted the concept data study which was required to get started and then we embarked on the architectural solution design which formed the backbone for this program. The next important milestone for this was the implementation of the system that we built for rate switch function functionality for the brokers. After that, we moved on to implementation of the system with the consumer portal, which provided more features for the brokers and consumers to deal with. And if you look at the program today, we've got the best part of 150 people. You woud  find it difficult if not impossible to identify those people that are uncomfortable sort of payroll and those people that have been provided by TCS, which I think has been a real real sort of building block for us in terms of the success of the programme.
