An organization has found that a significant amount of rework is required because tickets are...

The approach to reduce rework is to train agents to capture the information required by each support team (B). The ITIL 4 Specialist: Create, Deliver and Support documentation (Section 4.1.3) states: "Training service desk agents to collect comprehensive and accurate ticket data reduces escalation rework by ensuring higher tiers receive sufficient context, minimizing delays and recurring incidents." This empowers first-line support, unlike option A (validation is reactive), option C (restricts ticket use), or option D (swarming is broader but less targeted). The guide notes: "Effective training enhances ticket quality and resolution efficiency."
