copied!<p>Git will not provide the "change management" process you're looking for. This is one of those management requirements that commercial version control systems like to advertise to attract businesses with shiny objects. That doesn't mean you can't do it, it's just outside the domain of git's purpose. Much like, authentication and access control (you can use ssh, and gitolite, but git itself does not provide these services). You'll probably need to develop this integration yourself unless you work with a common bug tracking tool.</p> <p>Locking files is always wrong. This is what "merging" is for.</p> <p>I currently work on a codebase of ~200,000 lines of code with 10 developers and git works very well. We have groups an order of magnitude larger also using git on other projects. Git's strength lies in merging and this is how it deals with multiple developers and lots of commits. Keep in mind, every push is a merge in git, whether it looks like it or not. Your local repository may have a branch named <code>master</code>, but it's not the same branch as <code>master</code> in the central repository. To synchronize them, you do a merge, which sometimes just is a "fast-forward merge".</p> <p>We don't bother to force a strong link to change requests. When I considered writing an interface to do this, one problem I ran into was how to make the dumb tracking system aware of every branch a bug is in. A simple hook isn't enough for this.</p> <p>You should move to git for the development process improvement. For me, it's fundamentally altered (improved) the way I write code. You'll be challenged to present a case for git doing change management better in business-speak without all the prepackaged bullets that come from expensive IBM tools. The real problem is, once you embrace git, you'll never be able to work with any of the other tools again, no matter how good a business case they present...</p>
