In Agile and Disciplined Agile practices, iterations are plannedat the beginning of each iterationduring an iteration planning meeting. The team, along with the product owner, pulls the highest-priority items from the product backlog that they believe can be completed within the iteration. This ensures that the work is well- defined, understood, and aligned with the current goals and priorities.
