The document discusses the need for Estonia's government systems to shift from a traditional "box and jar" approach to a more modern API-first approach to better serve citizens. It outlines some of the challenges governments face in making this transition, including legacy systems, poor mobile usability, and the need to support third-party integration through well-defined APIs. The document proposes adopting an API-first policy, treating open data as APIs, and developing prototypes and reference architectures to help shift thinking and enable this new approach in a practical way through small, initial steps.
