A service desk team acts as a single point of contact for its users.

The concept of swarming would help resolve this situation (D). The ITIL 4 Specialist: Create, Deliver and Support documentation (Section 4.3.5) defines swarming as: "A collaborative approach where multiple team members, including first- and second-line support, work together on an incident simultaneously to resolve it quickly, reducing queue buildup." This contrasts with the tiered structure’s escalation delays. Option A focuses on metrics; option B aids analysis; and option C shifts work externally, none addressing queue reduction directly. The guide notes: "Swarming enhances resolution times by leveraging collective expertise."
