Something we frequently hear, when talking to those involved in the federal contracting industry, is that just when you think you have a handle on all the different ways federal contracting is run, you find out about another new program, authority, protest, guidance, regulation, or any other possible wrinkle of federal contracting. One prime example of this is that many individuals getting into federal contracting will often be surprised that the FAR is not the only standard that may drive how a procurement activity is handled. As we have blogged about in the past, “Other Transaction Authority” can come into play on certain procurements. The Department of Defense (“DoD”) utilizes this unique type of procurement authority and releases an “Other Transaction Guide” to dictate how this authority will be used. But with all things, only change is guaranteed, and any contractor who thought they knew this unique procurement authority’s ins and outs will need to take another look, as the DoD has just released a revised “Other Transactions Guide” based on industry guidance and regulatory changes.
