Pros
Everyone is very professional, mannered, knowledgeable, and focused on teamwork. There is very little internal politics here relative to the much larger Pratt & Whitney. As a small organization with plenty of work to be done, everyone is focused on the job and less so on personal advantage at the expense of co-workers. Probably one of the best group of people I've ever worked with during my career.
Cons
PWPS was a standalone division, but was brought "inside" into Pratt & Whitney ("Big Pratt") once they started turning a profit. Consequently, they inherited all of Pratt & Whitney's substantial policies & procedures, which dampened the "small company" feel of the division. Note that this division would have rated very high in all categories had it not been for a specific non-engineering manager whose apparent lack of interpersonal and teamwork skills unfortunately resulted in very high turnover of his direct reports.
