Pros
Amazing depth and breadth of technical expertise. THIS is what sets Battelle apart from the competition-- the ability to bring top-notch technical talent to bear on the most challenging government and commercial problems.
Cons
It is difficult to not mirror other reviews. Poor long term planning, colossal internal project over-spends, and chasing short-term financial carrots (including ridiculous VP-level incentive goals) result in a volatile, pins-and-needles work environment. Technical staff have been turned into hamsters on the time-worked wheel, with little time for development or growth outside of project work. New grandiose yet vacant buildings, nonsensical "synergies" between product lines, and poorly implemented enterprise management systems (read: VP / CxO "vision") have all been sinks to Battelle's bottom line, while core technical activities keep us afloat. But barely. And at the cost of long term staff satisfaction, technical growth, and Battelle's position as a preeminent technical powerhouse.
