DataLab is a newly founded (since february 2022) centre of excellence for all topics related to data and data analytics within the Fortenova Group. This presentation will be two-fold. In the first part, we will talk about the organization, its structure, evolvement, goals and recruitment. In the second, we will present a case study on demand forecasting in companies Konzum and Mercator, describing all the necessary steps: migrating the data from local data warehouses to cloud, data preprocessing, modelling, evaluation, and industrialization.
