Over the last couple of years, we have worked very hard to transform the 
Marks and Spencer's Sparks loyalty program from a traditional card based 
points program to something digitally centric, a customer engagement 
platform ready for the future. And that's really required us to think very 
carefully about what this new customer experience is that we need something 
that is seamless, that works on every single part of the M&S shopping trip. 
And truly passionate to the customer as well. Our biggest problem was our 
legacy monolithic application that prevented us scaling and meeting the 
future demands for the business. So we decided to partner with TCS and build 
our own be spoke solution and build the system in a microservices based 
architecture so that we can keep the system agile and we can replace 
components of that without having to replace the whole. Ms. strategy for the 
loyalty platform gives them much greater control and the power to help in 
personalized shopping. We leveraged our deep contextual knowledge and domain 
expertise to deliver this platform which is future ready and scalable. We 
collaborated with M&S Digital and Technology team and developed this 
solution in a much more agile way so that it helps delivering the business 
outcome much faster. Through our close relationship with TCS, we've managed 
to move the platform over to a new way of working. With continued operation 
and no interruption to the business or to our customers. We've had some 
amazing campaigns over the last year, one of them being our wonderful 12 
days of M&S powered by Sparks, which brought the best of M&S to our 
customers at that critical Christmas moment. Over 7 million customers take 
part in that campaign, but we have more broad ambitions for the program as 
well. And so we're delighted to have a capability and a platform that allows 
us to scale and accelerate that. I'm really proud of the work that we've 
done together, delivering a fantastic £3 million benefit to our business 
through cost savings.
