Which activity is included in the disposal process?

The disposal process in systems engineering involves the activities associated with the end-of-life phase of a system. Performing disposal is a critical activity within this process because it entails the actual execution of disposing of the system components according to regulations, environmental considerations, and organizational policies. This may include decommissioning the system, recycling components, safely managing hazardous materials, or transferring ownership. The focus here is on ensuring that the system is retired in a manner that minimizes risk to the environment and complies with any relevant guidelines.

The other options listed pertain to different phases or activities within the broader systems engineering lifecycle. Planning maintenance relates to the sustainment phase, analyzing system performance typically occurs during operational evaluation or testing phases, and conducting user training is primarily associated with system deployment and support. Each of these activities plays an important role throughout the system’s life but does not directly engage with the disposal process itself.
