A difficult incident is worked on by pulling several specialists from different teams into the same session at the same time; once it becomes clear who is best placed to continue, the others step away. What is this technique called?

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.

How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.

The options

Correct Swarming

Correct. Swarming brings many stakeholders to bear at once and then narrows down to whoever is best placed to carry on, which suits incidents whose ownership is not obvious up front.

Not correct Hierarchic escalation

Hierarchic escalation raises an incident to a higher level of management authority, typically to release resources or make a decision. It is a vertical move, not a collaborative working technique.

Not correct Escalation to a specialist support team

Escalation moves an incident sequentially to the team whose expertise the category points to, and that team then owns it alone. The distinguishing feature here is that the specialists work the incident simultaneously before ownership is settled.

Not correct Problem control

Problem control is a phase of problem management dealing with analysis of problems and documentation of workarounds and known errors, not a way of organising people around an active incident.

Why

Swarming is the collaborative counterpart to sequential escalation: instead of passing the incident from tier to tier, many people work it simultaneously and then disengage as the right owner emerges. It reflects the practice's emphasis on collaboration within and between teams.
