I recently created a simple Theme Prioritization Scoring Spreadsheet. I use this as part of the Certified Scrum Product Owner class that I conduct.
BigVisible Theme Prioritization Scoring Workshop – CSPO Class
Feel free to download and use. It currently does not weight the relative benefit of implementing a feature (epic, theme or user story) nor the penalty of not implementing though adding the weighting capability is simple enough.
If you are interested in taking an public scrum class with me, check out training.bigvisible.com
