A newly formed cloud-services team joins a home-robot product that already has an app team and a firmware team, and the new team adopts a much lighter Definition of Done than the other two, skipping several checks the existing teams both require, so what problem does this most directly create?
Select an answer to reveal the explanation.
Short Explanation
If two teams promise a sturdy bridge and the third promises "probably sturdy enough," the whole bridge only holds as strong as the weakest promise. When teams share one product, letting one team run a lighter Definition of Done means the combined Increment can't be trusted the same way the others expect it to be.
Full Explanation
When multiple teams contribute to a single product, the Definition of Done needs to be at least a shared baseline across all of them, because stakeholders and other teams rely on "Done" meaning the same thing no matter which team produced the work. A new team adopting a noticeably lighter standard quietly weakens that baseline: work from the cloud-services team can now enter the combined Increment having skipped checks the app and firmware teams both consider essential, which reintroduces exactly the kind of risk a Definition of Done exists to prevent. This is not a matter of technology-specific preference, since some checks — such as integration testing or security review — apply regardless of which layer of the system a team works in, even if the specific tests differ in detail. Aligning Sprint length or Sprint Review scheduling across teams does not address the underlying quality gap at all; those are coordination details, not quality guarantees. The appropriate fix is for the new team to adopt the shared baseline Definition of Done used across the product, adding anything additional specific to its own technology on top of that floor rather than instead of it. A practical check is to compare the three teams' Definition of Done documents side by side and confirm every shared-baseline item appears in all three — any missing line is a gap in what the combined Increment can be trusted to mean.
