Vantaggi
The culture is great at identifying (really and honestly) what the sticking points are. They discuss setbacks openly and almost welcome them as the inevitable price you pay to build better stuff. It's refreshing to work in a company so motivated to deal with their own issues -- and not have it just be lip-service, as in other places I have worked.
Svantaggi
Continuous improvement is one mainstay of the culture, and productivity is the other. It seems like most employees have to *improve* their jobs and *do* their jobs at the same time. (There is no "steady state.") Because of this dual mandate, the work day is just packed -- there's little down-time to soak it all in, to stop and have lunch with coworkers, etc. Once at work, you are at work, period. (It's a good thing that most people like the work that they do.)
