This doc revolves on three major concepts ー Teams (the groups of people building features), Milestones (the major gates to full launch), and Features (the individual work items). These concepts are linked together so you can quickly see how features are progressing against each milestone both at a team and a milestone level. You'll also find a Funding Tracker, which can be used to quickly surface any features which are in danger of slipping given lack of resources to deliver it.
