The first commitment of STF is that events do not emerge in isolation. Every outcome, occurrence, condition, object, institution, or process is produced, maintained, or transformed by one or more systems. The task of the systems thinker is therefore not merely to describe an event, but to identify the systems responsible for its existence and persistence. This principle shifts inquiry away from isolated actors and singular causes toward the structures, relationships, and processes that generate observable outcomes. It is the foundation upon which all other STF principles rest.
