Pre-commit code reviews are usually ad hoc for us. Simpler changes may undergo no review while larger refactors are almost always reviewed with multiple people.

At the very least, about 2/3 of the way through the coding process, we again go through the code and make sure to identify ways we're deviating from the intended design. This gives us a bit of time to correct any issues and retest everything before moving on.

We just use TFS.
