Definition of Done in Scrum
What does it mean when something is “Done”? Especially in software development people’s expectations vary when they hear “Done” significantly. It could mean anything from “finished coding” to “written and tested” to “documented, released and blogged about it”. In Scrum, a dev team and their product owner compare expectations and agree on a shared Definition of Done.
To make it less abstract, I’ve included two examples of real-world DoDs. They are from the same company, five years apart. You might notice that the older one is more inward-looking and the newer one more customer-focused. It is also shorter, e.g. tests are not specifically mentioned. That is not because this team didn’t write tests anymore but because writing tests (and many other things) had become second nature several years before. If at any point the PO and dev team had noticed mismatched expectations about testing, they would have come to an agreement and added it to the DoD.
Neither of these DoDs is better or worse than the other. Each DoD reflects the joint expectations of PO and dev team at that time. They were the ultimate checklist whether they had thought of everything.Get PDF
The Definition of Done has an unofficial brother, the Definition of Ready. The DoR captures the shared understanding of when a product backlog item is groomed well enough to be worked on in a sprint. I hope to cover it soon.

Definition of Done
What can you expect when a team declares a piece of work “Done”?
In a Scrum team, the dev team and product owner capture their shared understanding of “Done” in the DoD. Paraphrased from the Scrum Guide:
Each sprint, teams strive to deliver potentially releasable functionality that adheres to their DoD. When a sprint backlog item is described as “Done”, everyone must understand what “Done” means.” The DoD varies significantly between teams and influences how many items a team can take on per sprint. Each increment must be thoroughly tested to ensure that everything works together. As a team matures, we expect it to adapt its DoD to ensure higher quality.
These are two DoDs from the same company, five years apart. Neither of these is better or worse than the other. Each DoD reflects the joint expectations of PO and dev team at that time. They updated the DoD whenever they discovered gaps.
