Our small software startup recently spoke with a program office at a federal agency about a prototype. They suggested it could be done as an "other transaction" instead of a traditional FAR contract, potentially through a consortium. This is new territory for us; we typically bid on firm-fixed-price contracts for software development (NAICS 541511). We've only ever dealt with the FAR.
I understand that an other transaction agreement (OTA) sits outside the FAR, but I am trying to grasp what that truly means for us. What are the key differences in how OTAs are managed and awarded compared to FAR contracts? Also, the program office mentioned something about being a "nontraditional defense contractor." As a company with no DCAA history, does this help or hinder us in pursuing an OTA? What does consortium membership typically entail, and is it a realistic path for a small company like ours?
