Explanation
Swarming is an alternative to the tiered support structure that would help to improve the situation. Swarming is a workflow management method that features in ITIL 4 Specialist: Create, Deliver and Support. It is designed for organizations that support complex systems or services. Swarming involves stakeholders working together to resolve the issue, rather than escalating it through different levels of support. Swarming can be used to identify the responsible group for the next action, or a swarm might be responsible for resolution.
Swarming is a technique to more effectively resolve complicated and complex issues, which typically require more than one person or group to complete an activity effectively. Swarming can also help to disseminate knowledge and experience among the support staff, and reduce the queues and delays caused by the escalation process. The other options are not relevant to the situation. Data analytics is the process of analyzing data to generate insights and support decision making. Robotic process automation is the use of software robots to automate repetitive and rule-based tasks. Continuous integration is a software development practice that involves merging code changes frequently and testing them automatically. References:
