They may not refer to the acronym "POSTED" exactly, but said acronym is what I learned and I thought highlighted the scope of what a system covers, specifically that it is not just the equipment i.e.: software. In the NASA SE Handbook, page 3 says the following, which essentially maps across to what I described:
"A “system” is a construct or collection of different elements that together produce results not obtainable by the elements alone. The elements, or parts, can include people, hardware, software, facilities, policies, and documents; that is, all things required to produce system-level results."
Same idea either way - the system is far more than just the equipment/technology.
