What is the definition of done?
The definition of done is a team's shared agreement on when work is finished. What belongs in it, and why without one the word means nothing.
The definition of done is a team's agreement about what “done” means. It applies to all work equally, and it is the reason a card in the last column means the same thing to everyone.
What belongs in it
Only conditions every item can satisfy: tested, reviewed, documented, deployed. Anything that varies per item does not go here but into that card's acceptance criteria — the distinction most teams blur at first.
Why it matters
Without it, “done” means “works on my machine” to the developer, “unreviewed” to the reviewer and “not shipped” to the customer. All three say the same word and mean different things — sprints fail on this more reliably than on bad estimates.
In Zuuna
As a checklist on the card, or as a column rule that blocks the transition while items are still open.
FAQ
How long should it be?
Short enough that everyone knows it by heart — usually five to eight points. A list of twenty is not read, it is ticked.
May it change?
Yes, and it should. The retrospective is the usual place. What must not change is its validity in the middle of a sprint.
