I'm not sure what EPA can do to make it more useful. My personal example is the USEPA/USEEIO modeling framework [1]. My agency uses a pricey and rigid proprietary modeling framework. When I suggested USEEIO as an extensible cost-effective alternative I was met with resistance that it is free and mustn't be any good and definitely not defensible in court. Classic .gov thinking. I think DoD prioritizing open-source along with the work of USDS/GSA at digital.gov needs to diffuse to Senior Execs at other agencies to shift the paradigm. Unfortunately it feels like this is a decade out. Thank you for pushing OSS in .gov and to your peers at EPA for USEEIO.
