The approach that may help is shift-left (C). The ITIL 4 Specialist: Create, Deliver and Support documentation (Section 3.3.1) states: "The shift-left approach moves support activities to frontline teams or users through self-service or enhanced first-line capabilities, reducing resolution times by minimizing escalations to specialists." This directly addresses the scenario, unlike option A (prioritization method), option B (team collaboration), or option D (automation tool). The guide notes: "Shift-left enhances efficiency and user empowerment in incident management." Reference: ITIL 4 Specialist: Create, Deliver and Support, Section 3.3.1 - Shift-Left Approach.
