The Portfolio Backlog at the Organizational level, the top level of all Backlogs, contains Systems, Products and Application variants, as well as product variants for special markets. Each of these product variants is described by a set of System Requirements (feature set). In this way, the product variants can be estimated against each other with regard to both the benefits and the effort to be invested . The so-called Upswing Gravity Field is used for this in the P4 framework .
The Portfolio level is not necessary for organizations that create only one product.
