Nonfeedback
Nonfeedback refers to the absence of a feedback mechanism within a system, process, or interaction, meaning that the system's output does not influence its future input or behavior. In engineering and related fields it is commonly used interchangeably with 'open-loop' control. Nonfeedback contrasts with feedback-enabled designs where the output is measured and used to adjust inputs.
In control engineering, a nonfeedback or open-loop system applies a predetermined control signal to its actuators
In information theory and communications, a nonfeedback channel is one in which the transmitter does not receive
In other domains, nonfeedback may describe instructional approaches, organizational processes, or user interfaces that do not
