Pros
Opportunities to grow are good. We are a strong company, and I think we have a pretty good business model. I think the organization does allow for innovative approaches to be tried, but with a pretty short leash. I have worked at companies that are FAR less amenable to change and think progressively. Comparatively, I think we focus less on Wall Street than other consulting firms - maybe the Dutch influence, but we seem to have more long term thinking that just "what will the stock price do at end the month" that I have seen elsewhere among senior management.
Cons
With all the acquisitions, we are becoming much more bureaucratic. Too many mundane decisions are pushed too far up the ladder - more local authority (and responsibility) would allow us to be more nimble.
