On the menu of this restaurant south of Nantes (Loire-Atlantique), homemade dishes, and dozens of pieces of information collected throughout the day. Digital version, we call it data. An example, the price of the dish of the day, the number of people who ordered a burger dish on Saturday, or the price negotiated with a ticket supplier. All this data, the establishment decided to use it, how? By paying 250 euros per month, to use computer software. Gaétan Giraud, general manager of the Black shelter, shows us the technical sheet of a dish created using the software. It contains the exact shot of each product updated every 20 minutes. He therefore knows his margin in real time. When a dish is no longer profitable enough, it turns red and leaves the menu. Hundreds of bills each month that had to be analyzed to find out if the restaurant was making enough money, impossible to do every day. Being more profitable thanks to data is no longer reserved for CAC40 companies. In this Montpellier SME, we rent excavators and tools for construction sites. And here, too, have produced data. When a machine is rented, its departure time and destination are recorded. During a maintenance, the repair time and the parts used are noted. THE SME has invested 50,000 euros in a dashboard that brings together all this information. With one click, the company can know which machine is the most profitable, which is not rented enough. Results more serenity in investments. More details in the video at the top of this article. TF1 | Report T. Jarrion, C. Moutot
