Our client is one of the leading retail businesses in Spain, boasting a strong presence in the market with a wide range of products and services. With a commitment to innovation and staying ahead in the competitive landscape, the client has invested heavily in technology to streamline operations and enhance customer experiences.

The company relies on data analytics for critical business decisions, from inventory management to customer segmentation and sales forecasting. Tableau Server serves as the central platform for sharing insights across the organization.

Client Problem

Despite their success, the client faced a critical challenge with their existing Tableau Server version. Running on an outdated system posed several risks:
