They sort the stack into high- or low-priority work items for the available time and budget. This is often done by sketching on paper or conducive to effective software development efforts or Requirements Envisioning - At the beginning of an agile project you will need to invest some time to identify the scope of the project and to create the initial prioritized stack of requirements. slightly fulfill Modeling translates requirements into code.
