Three Scrum Teams work together on one product. Each has written its own Definition of Done, and they disagree about what "tested" requires. What does Scrum require them to do?
Professional Scrum Master I, objective 1. Understanding and applying the Scrum framework medium
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
The options
Correct They must mutually define and comply with the same Definition of Done
Correct. One product means one meaning of Done, and mutually is the operative word — it is agreed between the teams rather than handed to them.
Not correct Each team may keep its own, as long as every one of them is at least as strict as the organisation's standard
Wrong. That still leaves the product's Increments inconsistent with each other, so nobody can say what the combined result of a Sprint actually is.
Not correct The strictest of the three definitions automatically applies to all three teams
Wrong in method even if the outcome sometimes looks similar. Scrum asks the teams to define it mutually, not for the most demanding team to impose its version on the others.
Not correct The Product Owner selects one of the three, since they are accountable for the value of the product
Wrong. The Definition of Done is not the Product Owner's to choose. It is the Increment's commitment and it belongs to the teams building the product.
Why
Everything that keeps multiple teams building one product rather than three lines up here: the same Product Goal, the same Product Backlog, the same Product Owner, and the same Definition of Done. Increments have to be additive across teams and thoroughly verified so they work together, which is impossible if Done means something different depending on who built it.

- What it says
- If there are multiple Scrum Teams working together on a product, they must mutually define and comply with the same Definition of Done.

More questions on this objective
- A department is choosing an approach for a product where both the requirements and the technology are poorly understood and keep changing as the team learns. Someone argues for Scrum "because it is founded on empiricism". What does founding an approach on empiricism actually commit the team to? machine-checked
- At the end of a Sprint three items are functionally complete but have not been through the automated test suite the Definition of Done requires. To avoid an awkward conversation the Developers mark them Done on the board and include them in the Sprint Review. Which pillar has been damaged, and what follows from that? machine-checked
- A Scrum Team holds every event on schedule, keeps a burn-down chart and reviews its metrics carefully. For six Sprints running, the same impediment — a two-day wait for a shared test environment — has been named in the Retrospective, and nothing about it has changed. What is the accurate diagnosis? machine-checked
- Mid-Sprint, the Developers discover that a third-party API rate-limits far below what they assumed, which makes the current plan unworkable. One of them suggests carrying on as planned and raising it at the Sprint Retrospective, so the Sprint is not disrupted. What should happen instead? machine-checked
- Which THREE of these statements about Scrum theory are accurate as the framework defines it? machine-checked
- A Developer is fairly sure the design the team agreed last week will not scale. The team is halfway through the Sprint, everyone else seems content, and saying so means an uncomfortable conversation and probably rework. Which Scrum value most directly asks them to speak? machine-checked
