Pros
Stable challenging environment. Management tends to be fair (Although it depends on who your manager is). I have never had a bad manager. The same cant be said for many of the senior managers - They very often seem quite disconnected from reality and often times our employees and customers suffer because of it. However, if you stand up for what you believe is right and fight hard, you can most often win the battle.
Cons
Our technology is supposed to be superior - and it is as long as the customer can give us the data we need in the exact format we need it in. If the customers not flexible, we usually get into trouble. I think that will change soon as we are making significant upgrades to many of our systems and the future looks bright.
