Yes, there's the great framework called PRICE. It's calculated based on how much people are willing to pay to have the problems solved!! :-)

Actually I describe the framework in the article. Everything we do in product should be guided by higher level vision, objectives and strategy. The problems etc that align with that should take priority.

If you've got those covered then anything else is opportunistic based on other needs. Hope this helps. If you need more detail, let me know.
