A few things about the matrix:
It contains every provision and clause in the FAR, DFARS, and in DoD Class Deviation memoranda. It doesn't have any "Principle Type and/or Purpose of Contract" columns except for a Commercial Items column. It contains the actual prescription of the provision or clause. For readability, I removed the number and title of the provision or clause in the block and just wrote "use this provision..." or "use this clause..." The identifying information for the provision or clause is already contained in the row. For DoD, it contains additional instructions for the use of FAR clauses that is contained in the DFARS or in a class deviation. This information appears in bold. If you work for a civilian agency, just ignore what's in bold. In the "IBR" column (Incorporation by Reference), there are no "N" entries for "no", with the exception of the provisions and clauses prescribed at FAR 52.107. This may cause some people to freak out, so I'll explain. FAR 52.102(c) states: Thus, if the FAR Matrix contained a "Y" in the IBR column, my matrix will also contain a "Y". If the FAR Matrix contained an "N" in the IBR column, or the provision or clause came from the DFARS or a DoD class deviation, then my matrix will contain a "Y*". The key at the top of the matrix contains an explanation for the "Y*" entry. If you're wondering how to incorporate a provision or clause that contains fill-in material or something the offeror must complete, see FAR 52.102(a) and FAR 52.104(d).
You can see the matrix on the DAU Acquisition Community Connection. I'm open to suggestions for making it better. Also, I would like to think that it doesn't contain any errors. However, if you spot one please let me know. As an incentive, I will add your agency's provisions and clauses (the ones in Title 48 of the CFR) to the matrix if you point out a mistake.
