Institutions play a crucial role in initiating and bringing about transitions. Heavily institutionalised systems can thwart transitions, while other institutions - or the absence thereof - can significantly boost innovation. Although there is no unambiguous definition of the concept of institutions, they are often seen as the rules of the game. These rules - formally seen as laws and regulations and informally as norms and values - find meaning in facilitating and coordinating interaction between individuals and organisations. In doing so, they hold various possibilities, limitations and conditions that can ultimately influence the effectiveness and lifespan of transitions. The games are often played in different political, economic and social arenas, but often also in between.
