Estimate-risk spreadsheet

I stumble upon a wonderful tool created by Robin probably a long time ago. (http://www.agilemetrics.com/tools/estimates-risk.html).

You’ll see a spreadsheet captures the Stories (Requirements) in a visual and easily risk ranked way. “One of the nice things it does is provide a framework for quickly capturing subjective customer (business) perception of the stability/completeness of their requirements. It then uses this to give a graphical representation of the Estimates/Risk of the project.”
