A customer support team uses short iterative cycles to resolve customer issues. A surge of high-priority issues disrupted the plan and the manager is struggling to manage progress. Which approach should the project manager recommend?

The Agile Kanban approach is best suited here because it focuses on visualizing work, limiting work in progress (WIP), and managing flow. This allows the team to adapt quickly to the surge of high-priority issues without disrupting the overall plan, as new priorities can be pulled into the workflow as capacity becomes available. The Agile Scrum approach uses fixed-length sprints and a defined backlog, which would be disrupted by a sudden surge of high-priority, unplanned issues. The Spiral approach is a risk-driven model for large, complex projects, not suitable for managing daily customer support issues. Rapid Application Development (RAD) is an iterative development methodology focused on rapid prototyping and user feedback, not ideal for continuous issue resolution.
