The company I am currently working for utilizes an existing code review application that provides useful metrics about how many defects are found, how quickly they are fixed, what developers are working on, etc.

These metrics are very useful to the company and while I would very much like to be able to sell this tool because of its easy to use integration with Visual Studio, losing those metrics would be a show stopper in trying to get this software adopted. If the ability exists to show reporting and metrics about code review and usage, I might be able to successfully pitch this product.
