System Analysis...I caught myself napping!!!!

Well last week we did a system analysis on the case study or a system that we were familiar with.  Being as familiar with DOD computer systems as I am, I decided to analyze a Brigade level system on down.  I laid out all the basic framework and I didn't even think to include such things like the routers and switches that are actually required to run the system.  I mean in real life they are there I just didn't think to include them.  I also forgot to mention how the systems are maintained and controlled and stuff like that.  The entire S6 or commo shop is in charge of maintaining all of the systems.  Even though they appear on the individual company property books they are still incharge of conducting inventories as well as system updates.  All of this information eventually came out in response to my peers questions, but if given the chance I will edit my diagram and it will be easier to understand.
