Societal or socio-technical systems are complex dynamic systems. This means that changes take place continuously: new services are developed, new technologies are introduced to the market, decisions are made to do things differently, mutual task agreements are changed, or new players enter the market. In this sense, complex systems are always in motion. However, the degree of change and how the change is managed can differ greatly. Transitions can be driven internally (i.e. by players and incentives of the system itself) or more externally controlled, and their coordination can be vision-driven or take place more "emergently" (Berkhout et al., 2003). After studying different transitions, Schot and Geels (2007) define five stereotypical transition paths that can be followed by a system. These range from 'the path of reproduction' in which system interactions keep the regime (or the current structure of the system - the prevailing frames of thought, institutions and infrastructure) dynamically stable, to 'the path of reconfiguration' in which innovations increasingly challenge the architecture of the regime, or 'the path of substitution' where an innovation developed (and proven) parallel to the system breaks through to the regime. We are talking here about innovations, of a social or technological nature, that introduce a different practice with other necessary institutions and infrastructure.
