Formalized work routines and fossilized structures often are unhelpful for operating in and actively shaping complex and dynamic environments. We need a performative, fluent understanding of organization that is no longer entirely based on rational planning: the often hidden experience-based knowledge (tacit knowing) is the foundation of today's necessary -art- of improvisation. The contributions show how implicit and intuitive anticipatory knowledge along with experimental, playful actions provide the basis for innovation and learning in organizations and social systems. In the analysis of -organizational patterns- and -musical thinking-, a new understanding of more flexible and dynamic organizations emerges."
