The Rubicon Model is a psychological framework developed by German psychologist Heinz Heckhausen and his collaborators. It focuses on the processes involved in decision-making and goal achievement, particularly the transition from motivation to action. The model distinguishes between different phases in this process, highlighting how individuals move from the stage of consideration to the execution of their goals.
