Scholz (in press) proposes how Brunswik’s lens model can be extended to account for planning of sustainable transitions of complex system. In this commentary, an alternative extension is proposed, according to which planning is seen as a process that unfolds in three steps. The first step can be understood with a model construction lens: A planning team builds a representation, that is, a model of a (distal) complex system. In a second step, modeled with a planning lens, the team contrasts its representation of the system with possible alternative states, and simulates how the is-state could be transformed into an ought-state. In a third step, modeled with an implementation lens, the team selects and implements a set of actions, thereby leaving the “imaginary space” (Konrad Lorenz) and entering the real world.
