MITRE is doing SETA work for the government, competing with for-profit engineering companies. The FFRDC contracting mechanism allows them to respond to Government issues more easily than can for-profit SETA firms, so MITRE grows thanks to an unfair advantage. Because of MITRE, the Government has had to crack-down on all FFRDCs and impose strict STE restrictions. This is a shame as the other FFRDCs fill a very valuable need for our Government.
Somehow, MITRE has created the model of the self-licking ice cream cone where they advise the government what good systems engineering is. Problem is, MITRE provides very poor quality systems engineering because they don't actually practice it like the for-profit companies do. This lets MITRE peddle snake oil such as system of systems and MBSE and get away with it because they don't actually have to engineer any systems. You can say anything works if you don't have to take responsibility when it doesn't. Guess what, it doesn't.
