Increment

The sum of all completed product backlog items at the end of a sprint, plus the value of previous increments. An increment must meet the team's Definition of Done and be in a potentially shippable state — even if the product owner decides not to release it. Each increment is additive: every sprint builds on the work of all previous sprints. The increment is inspected at the sprint review, where stakeholders provide feedback. The Scrum framework requires that each increment be a concrete stepping stone toward the product goal — teams cannot call a sprint successful if the increment is not usable and potentially releasable.
