The Upswing Gravity Field is a wonderful visualization for feature prioritization of Product and Portfolio Backlogs. The upswing describes the added value of a product or a function, the gravity describes the effort that the organization has to spend to achieve this. The priority corresponds to the quotient of value and effort (priority = value / effort). By using logarithmic quantities, such as in the Fibonacci sequence, a double logarithmic representation and a rotation of 45 degrees, we get these perfectly parallel priority lines.
Typically, Product Owners can best estimate the added value or the market value of different products against each other, but have less expertise in estimating the effort to implement. It is exactly the opposite with the Working Teams: They have the best understanding of implementation costs from all those involved in product development, but cannot estimate the market value as well. Therefore, in the P4 framework, added value and effort are estimated separately and shown in the upswing gravity field. It is a powerful tool for the product owner to assess priorities.
