Pros
Many of the practices have bright and capable professionals and leadership. Overall firm values around "one firm" are right strategic approach (if not fully realized). Some innovative and progressive areas (for example around data and analytics). Audit and Tax have some very strong and skilled practices and, when coordination across groups occurs, can be very value added to clients.
Cons
Practice areas are not consistent in living the values. A lot of infighting and ugly politics. As a result of this, as well as a cumbersome national member firm structure and conflicting agendas for tax, audit and advisory, the "one firm" vision frequently falls short. Extremely risk averse culture. Advisory leadership mostly driven by monthly numbers and does little to inspire or lead.
