Would you elaborate on the terrible job we do?

Are you serious?

TFS is such a bad product that most teams at Microsoft don't use it.

You use XAML to configure builds.

The source control system still uses a locking workflow.

The issue tracker managed to be under powered and over complex at the same time.

I had to suffer through it at two previous jobs. Never again.

Take a look at the competition. There is no single part of TFS that isn't done much better elsewhere.

The only reason it still exists as a product is because of Microsofts sales force, not it's own qualities.

File editing/locking/merging isn't great, particularly if we've got Excel in our Source Control. We can either have everyone lock files or everyone merge. You can't merge Excel files so it means everyone has to lock or we store Excel elsewhere.

Unix Client is flaky and inconsistent and doesn't get much love.

I can't put a version number into a file so I can see in Prod what version the code is.

I could go on.
