Which change type primarily maintains the ongoing function of a system?

First order change is focused on making adjustments or modifications to existing behaviors or processes within a system without altering the fundamental structure or patterns. This type of change typically involves incremental improvements and adaptations that help maintain stability and functionality within the system.

For instance, in a family therapy context, a therapist may work with a family to alter communication patterns or resolve conflicts, which can lead to more effective interactions while preserving the family's underlying structure and dynamics. Thus, first order change is essential for ensuring that the system continues to operate effectively, as it involves adjustments that stabilize and enhance current functioning without challenging the overall system's integrity.

In contrast, second order change involves a transformation of the system's fundamental rules, beliefs, or structures. Morphogenesis refers to the process of development or evolution in the structure of a system. Negative feedback is a mechanism that helps maintain stability by counteracting changes, but it does not specifically represent a type of change that ensures ongoing function. First order change remains the most appropriate choice for maintaining ongoing function while preventing disruption to the system as a whole.
