The document discusses how the Danish government innovation lab MindLab is helping transform the public sector through citizen-centered innovation. It outlines MindLab's approach of engaging citizens as co-developers to meet citizens' expectations for better public policies and services with fewer resources. The document also provides three key lessons learned from MindLab's work: 1) citizen-centered innovation is effective but requires leadership and employee skills; 2) there is untapped value to be found through better services at no extra cost, but the public sector isn't used to value creation; and 3) a change agent like MindLab is needed to drive cross-government collaboration, with top management focus and support.
