Is there a standard for using the Item number system and the Find number system in assemblies

I am trying to make a standard that my students can follow. But my boss thinks that I should stick to the DOD and MIL-SPEC standard or at least close to it. But in my tenure as a draftsman I never had to use DOD or MIL_SPEC for assemblies which is the Item number system. Apparently I have only used the Find number system. It very easy to use and to understand. The DOD standard, although I consider it Top of the Line way to make assembly drawings, I am not familiar with it. I mean what are the chances that all of my students will be using the DOD standard after they graduate from this program? So, I feel that my boss can teach them the DOD style and I can teach the simple style of assembly drawings. Now my only dilemma is that i need to find a manual that would help me separate these two and by the book. thanks
