We were asked to ensure high data quality for a Luxembourg railway company’s passenger information system. This project required a precise understanding of user needs and the implementation of an effective testing strategy. Challenges included managing a test team, developing processes for 28 Work Packages, and automating tests for APIs and user interfaces. It was crucial that all the elements delivered, whether code, documentation or user stories, met the required quality standards.
Founded in 1946, the Luxembourg railway company is a key player in public transport in Luxembourg. Managing a network of 275 kilometers of track, it carries around 25 million passengers and 105 million tons of freight every year. Technological innovation is at the heart of its success, with the development of advanced digital tools to enhance the user experience and optimize traffic and service management. The company is actively involved in modernizing its infrastructure, reflecting its commitment to sustainability and operational efficiency.
