Pros
There's a lot of smart, capable and pleasant people in all the offices, and with decent benefits and salaries, but the best opportunities in terms of job growth and promotions are mainly confined to the Ann Arbor HQ office. The products produced, especially the long-established ones, are of high quality and well-regarded by the customers, which contributes to a positive pride-in-product attitude among the employees.
Cons
If you are not in Ann Arbor, having your opinion seriously considered is challenging. Independent thinking and calculated risk taking are not encouraged and when they occasionally are, they usually get mired in over-engineered project plans and too many rounds of meetings. The lack of an official compensation time policy especially for those that have to travel, fosters the idea that management does not trust their work force.
