Deutsche Telekom is the world's largest telecommunications provider. We are serving more than 250 million customers in fixed line and mobile business, and make around about €110 billion revenue each year, but that is not really our mission. As Jeff said yesterday, we want to bring love to our customers and make customers to fans. We believe that this is only possible if we become the leading digital telco. As one of the essences, we believe that this is a platform business. Platforms to scale, to provide a digital service, and that does not only apply to our customers, but we want also to bring love to our employees. And here Pega kicks in because we use Pega in the project HRcules to provide a digital service for all the HR services that we got. We face different local legislations that bring on top additional complexity. And the thing is, as it's legal, it always needs to be very precise.
Not a lot of room to maneuver. And that is something where Pega manages, with its Center-out technology, the orchestration of different systems that interact and bring a digital experience to our employees. When talking about digital transformation and going from a legacy system to a new digital platform, you need to empty the old platform, you need to either stop doing or migrate the stuff that you need. And that is where the value comes in. Because for those processes it says good is good enough. And by emptying those, we are able to pull the plug on the legacy system, because those benefits just materialize when you're done with your full program. And by that free up multi millions of euro, which we are currently spending in application operation and application management. And with Pega Blueprint, business has the chance to describe processes in their own words, with their terms, with what is meaningful to them. And the beauty of Pega Blueprint is that it adds on top things business tends to forget.
Like the unhappy path. What happens when we cancel? Where is a loop, if there is anything forgotten so that we just not define the perfect world. And even if we would just use Blueprint as a checklist to run through the cornerstones of a project, that provides a structure that translates into speed. With the preview function of Blueprint, we have a clear idea on what we can expect, and that reduces double work in implementation and brings us closer to going live. And that is something I really appreciate in teaming up with Pega, because we expressed our concern and our business challenge, and you guys made it your challenge as well, and strong collaboration and partnership just across the whole last year. And I really look forward for this. And mentioning Alan specifically, last year at this point, he promised to double developer productivity. Seems like you delivered on that one.
But on top, I also see that Blueprint significantly increases productivity on the business side in IT projects.
