How the gate runs

Predictive

Phase gate: held once, at the end of the stage.

Agile (iterative)

Rolling gate: held per release; item readiness via Definition of Ready, completion via Definition of Done.

Flow (Kanban)

Policy gate: explicit exit policies on the board columns, applied to every item.

Hybrid

Phase gate per phase, with iterations or flow inside the phase.
