Pros
Just about every process is in need of improvement, so there's lots of work for a LONG time. There are 1100+ s/w systems that don't talk. It's a company run by Excel spreadsheets (not a positive).
Cons
Wild West mentality. Try telling a cowboy he needs a different saddle ! It doesn't go over well. Working hard is embraced and working hard is scolded upon. Actually thinking is scolded upon. If you sit at your cube with a pencil in your hand looking at the wall (thinking), you will get funny looks as your not 'producing' anything. I would sum it up as the opposite of apple. There are lots of people set in their ways and management is not committed to making the process more efficient and effective. Heck, the $16B company did not have a supply chain network up until 3 years ago..
