The Definition of Done being binary—either Done or not Done—is important for maintaining transparency and clarity around the product’s current state. This clear distinction prevents the reporting of partially Done work, which can lead to confusion and false assumptions about the product’s readiness.
A binary DoD ensures that only fully completed work is considered for inspection and potential Release, maintaining high standards of quality. It also supports effective planning and forecasting, as the team can accurately assess what work is complete and what remains to be done.
