Dashboard is a term of art in metrics-focused organizations, made by analogy to the dashboard of a car, which is the part that has the spedometer and other statistical displays that tell are designed to convey a lot of information at a glance while you're doing more important things (i.e. getting where you're going without killing any little old ladies with your car).

Anyhow, the actual implementation is just a web page (or similar) which has stats, graphs, etc for whatever metrics you want to display, designed to be quickly comprehensible.

If you give me a few hours to get back to my apartment (and Paint.NET) I'll screenshot mine, block out the private customer data, and show you.
