For the VCS, do you mean Clearcase? Clearcase was a good idea in 2001, when the alternative was CVS. In 2015, I am wholeheartedly unconvinced it offers anything over git. (And I'm not a devoted booster of git.) (I was nominally responsible for a Clearcase setup at Ericsson in 2001. I mentioned it in passing on the 2002 version of my CV, and no later version. I still get pings from those last few Clearcase shops, desperate to find someone willing to touch the thing.) You may disagree, and perhaps Clearcase has substantially changed its model since then. What in detail do you like about Clearcase over (say) git?
