To be honest, we have not really had a lot of experience with this tool. We sort of installed it to meet a customer request requirement. It was an early version of the product about almost four years ago now. It didn't get much focus beyond that initial deployment. Now there is a renewed high interest in the product, so we have upgraded to the latest release. We understand that the product still has some growing pains, but we are impressed by the ability to integrate that product with Spectrum and with other tools. One of the things we want to focus on here is understanding the APIs for both Spectrum and for Performance Center so that we can more tightly integrate those products with other tools that we use.
