Delivery systems can also be envisioned as being concerned
with hardware barriers or behavioural (elements of)
barriers. In that case the life cycle of barriers, including
inspection and maintenance, would be considered the hardware
side of barriers, whereas the behavioural side would
be supported by the delivery systems procedures, manpower
planning, competence, commitment and communication.
These delivery systems all presume some human
involvement in barrier operation. This distinction between
hardware and behavioural barriers and their related management
delivery systems is made in the ARAMIS audit as well.
