The next Sprint involves a payments integration nobody on the Scrum Team has worked with before. The Product Owner suggests inviting a specialist from another team to Sprint Planning to advise. The Developers say that would compromise their self-management. Are they right?

Professional Scrum Master I, objective 2. Developing people and teams easy

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 No — the Scrum Team may invite other people to Sprint Planning to provide advice, and the decisions still remain the team's

Correct. Taking advice and surrendering a decision are different acts, and only the second would touch self-management.

Not correct Yes — Sprint Planning is for the Scrum Team alone, so nobody outside it may attend

Wrong. The Guide explicitly permits the Scrum Team to invite others to Sprint Planning for advice.

Not correct Yes — taking outside advice would mean the team is not cross-functional, so it must acquire the skill itself before starting

Wrong, and it is the plausible one because cross-functionality really does mean holding the skills needed. But Scrum expects teams to share or acquire skills as needed, and asking an expert a question is one of the ways they do it.

Not correct No, and the specialist should therefore decide how the integration work is broken down, since nobody else understands it

Wrong, and it is the sharper trap because it starts from the right answer. Advising is welcome; deciding is not — how selected items become Increments is at the sole discretion of the Developers.

Why

Self-management is often misread as isolation — nobody may help us, nobody may look in. It means the opposite of that: a team confident enough in its own authority to pull in whatever expertise the work needs. What would breach it is the specialist deciding rather than advising. Cross-functionality is about the team having the skills necessary to create value each Sprint, which includes acquiring them.
