What does the term 'Done' signify in Scrum?

In Scrum, the term 'Done' signifies that a task or product increment has met the Definition of Done criteria established by the Scrum Team. This Definition of Done is a clear and shared understanding that outlines the conditions under which work must be completed to be considered finished. It ensures that there is a consistent standard for completeness, which may include aspects such as coding standards, testing, documentation, and deployment. When a task is marked as 'Done,' it implies that it is potentially releasable and capable of being delivered to stakeholders, thereby enhancing transparency and quality within the Scrum process. This also supports the notion of commitment to quality and guarantees that the team is delivering valuable increments of work in each Sprint.
