Barcelona’s Digital Transformation Plan of Social Services is creating an integrated, user-centred digital system to improve coordination across more than 25 services and 50 resources supporting over 260,000 people each year. By replacing disconnected applications with a unified platform, the initiative aims to give professionals a 360º view of citizens’ social care trajectories, improve access and continuity of support, and reduce administrative burden. Developed through co-design with professionals and citizens, the practice combines system integration, the Barcelona Social App, omnichannel communication, and data-driven tools to enable more personalised, proactive, and efficient social services.
