You don\u2019t have to be in the retail to know what a big deal Black Friday is. The promotions for sales the day after the U.S. Thanksgiving holiday are everywhere, from billboards to online. The Balance, a personal finance content website points out that Black Friday is one of the biggest and most profitable retail days of the year. \n\nAnd the phenomenon extends far beyond the U.S.: Bustle.com reports that nearly 20 different countries have Black Friday sales of their own. But what if a retail company faced the prospect of its core digital systems being down during this pivotal four days?\n\nBuilding on a solid foundation\n\nAnd that brings us to Carrefour \u2013 a French group and a leading global retailer. Carrefour has been a pioneer in the large food retail business for 60 years. The company reaches more than 100 million households a year and gets over a million single visits to all of its online shopping websites every day.\n\nThat\u2019s impressive, right? But the leaders of Carrefour\u2019s Brazil unit were concerned that their old Enterprise Resource Planning (ERP) system would not be able to keep up with the demands of a post-pandemic world. It was time to take their technology to the next level \u2013 a new ERP in the cloud, that would be able to move more quickly and at the same time. Plus, save a great deal of money.\n\nFor whom the clock ticks\n\nAs they confronted this reality, the people at Carrefour were hearing the loud sound of a clock ticking. Black Friday was just a few months away. \u201cIf there was any delay in the delivery of the project, the current data center would have to be shut down. In other words, the company would increase its costs for demand in November, when Black Friday takes place,\u201d said Paulo Henrique Farroco, the CIO of Carrefour Brasil. At that point, they had a little over three months to get it done.\n\nThe power of partnership\n\nCarrefour chose SAP S\/4HANA as the only system that would cover their entire process from origination, risk management, and logistics through back-office processes like finance, accounting, and tax to operational processes. And they picked partner Mignow for the project because it was the most innovative option, where all the steps of their data migration could happen automatically, through software. Using artificial intelligence tools, it understands the database, diagnoses the project, automates the conversion steps, and performs automatic updates.\n\nHitting the mark\n\nWith all the pieces of the plan in place, Carrefour completed the migration to a new data center and connectivity services structure in just three months. The highly complex project included migrating from the old on-premise system to a Cloud Software-as-a-Service environment \u2013 updating the integration architecture using new middleware, and installing the very latest version of the new ERP. It was a major step into the future, and just as important, everything was ready well before Black Friday.\n\nAdding it all up\n\nCarrefour is already seeing the benefits from the project. It\u2019s reducing operating costs by 40%. The migration opens up the possibility for stores to predict whether the quantity of products ordered will increase or decrease, being ready for whatever their customers need. With more robust and faster analysis of sales orders, they\u2019re predicting an increase in profitability.\n\nCarrefour is even reducing energy consumption by 45% by moving from on-premise data centers to the cloud. The project minimized service disruption for shoppers and employees with seamless migration across on-premises apps. And Carrefour\u2019s Paulo Farroco adds, \u201cAs we continue to implement best practices and adapt our operations to the cloud, we\u2019ll be able to reduce our costs even further into the future.\u201d\n\nThis project earned Carrefour a winner\u2019s position at the 2022 SAP Innovation Awards, honoring organizations that have used SAP products, services, solutions, and offerings to benefit both business and society.
