Git has moved beyond open source projects into the enterprise software developer's toolbox. Git solves some old problems in unique ways, but introduces new challenges for developers, software architects, release engineers, and managers. See how Perforce Git Fusion overcomes these challenges while still taking advantage of everything Git has to offer.
