Scrum teams use definition of “done” to assess when work is complete on the product increment.
As per scrum guide when a product backlog item or an increment is described as “done”, everyone must understand what "done" means. Although this varies significantly per scrum team, members must have a shared understanding of what it means for work to be complete, to ensure transparency.
Daniel Gullo, Founder and Principal at Apple Brook Consulting, Certified Scrum Coach and Certified Scrum Trainer, shares his views on usage of definition of “done” in his recent blog. He says that there are different contexts of “done,” which can be applied at the story level, epic level, release level, product level, and so on.
Daneil says that there are different perspectives of “done”.
The word “done” is often used to mean “complete” as in the Development
Team saying: “We are done with this story.” It is also used to
indicate “acceptance” as in the Product Owner saying “This story is
done.” I typically teach and coach it this way: Don’t say “done.”
Instead, use “complete” and “accepted” for more specific indications
