One of my personal favorite source control systems is Git. I've always been a huge fan of it. It is very, very easy to use. Things like GitHub and Bitbucket do a great job of managing Git and making it really, really easy for us to do things like polar requests for code reviews, and the separation of code into different swim lanes. That kind of management is really hard to do in Harvest, and I'd like to see that brought into the CA Mainframe Software Manager (CA Harvest SCM) product. It does support us with our lifecycle, but the challenges with using it from a developer's point of view bring my score down a little bit. The features don’t always working as advertised.
