Pros
as an FFRDC (actually a holding company for multiple FFRDCs), MITRE _should_ appeal to technologists who are willing to sacrifice top-end wages for a job where they can have an impact (bad taste word when it comes to MITRE's FAA sponsor :-)) on government programs. opps, that doesn't sound all that "pro".
Cons
Under CEO Al Grasso and his push for "business" in non-DoD "customers", in the opinion of many MITRE employees, MITRE has lost it way. Now it is unlikely that a manager would walk away from "non-MITRE work". Has MITRE become just another Beltway Bandit? Sadly, the answer seems to be yes, unless Grasso chooses founding principles over his "lunch bunch"'s desire to follow in the footsteps of former CEO Barry "The Barry" Horowitz (sp?).
