What is the principle that some individual is accountable and responsible for government property from the time it enters the system until it is disposed of?

The principle that holds an individual accountable and responsible for government property from its entry into the system until its disposal is known as "property accountability." This principle ensures that designated personnel are responsible for the care, management, and proper usage of government assets, thereby maintaining integrity and preventing loss or misuse. It establishes a clear chain of responsibility, reinforcing the importance of stewardship in the management of public resources.
