Client success: Carrefour makes a successful journey to the cloud with PRISM

My name is Jan de Winter. I'm program manager at Carrefour Belgium. The whole project started, in 2017. It's, what we call the digital HR road map. And then in 2020, we started to work on the last part of the digital HR road map, which is the the replacement of our planning system, time and attendance system, and most difficult, the replacement of our payroll system. We designed the project in a different way so that we didn't have to rebuild important parts and so we could already save a lot of money. And so that's, that's the big advantage of the the PRISM approach. During the project, you also have benefits of two other solutions that we are using, Data Sync Manager and the Variance Monitor. The the most spectacular for me is the variance monitor because we use it to do the testing of the payroll system. So we are, in fact, recalculating all salaries of all employees for all months of 2021. We compare the results of it with the salaries that were calculated by the provider that we had in 2021. Based on that, we get some, statistics on, how many differences we have, and we can really work to close all the differences. After a few months, these results were so promising, that I could really use it to convince the Carrefour management that the project was in really good shape. It's making life much easier. If we would compare that with classic testing on scenarios, it would take much more time to do all the scenarios. And on top of that, we would never be sure if we had all the scenarios. So what we see is that, the the quality of service that we get from from EPI-USE and, the efficiency that they can bring in with the EPI-USE Labs solutions is, yeah, is very big. I think it will have a big effect on future projects in Belgium.
