The document discusses how AutoScout24 improved its product development process. Previously, development lacked user involvement and focused on broad market research. Now, AutoScout24 uses lean discovery and development principles. It observes users to understand problems, builds small solutions quickly, and measures results to learn and iterate. As an example, AutoScout24 developed a bookmarks feature for dealers to contact car buyers, releasing updates based on data from user interactions and conversations. This new process helps AutoScout24 get products to users faster that solve real problems.
