I recently worked on some measures/metrics that help answer the question "How effective is our product management process, and how is it contributing/affecting the overall performance of our product development line"
Here are some slides from slideshare about the topic. I might write it up in a more elaborate form in the future.
If there are specific questions about concepts I mentioned, mention it in a comment (or on twitter or something) and I might write up a specific area.
If you have examples of dashboards showing similar measures in practice, I'd love to see!
