I'm not a developer.. but did spend several years at BW working with their developers. Ask away, i will see if i can answer some of your questions.
SCRUM meetings, regular releases, change management.
The big difference is that people in BW work more as a collective and there is a lot less politics. This is what allows them to "get things done".
"Blustering" doesnt work well, you will get called out for it pretty quickly.
