PMP Practice: Apply Intervention Strategies

Shota Hayashi is managing a legacy system migration project for Turbulent Otter Games. The project involves upgrading warehouse management software across 12 distribution centers. During the planning phase, the team identified a critical impediment: a key vendor module required for real-time inventory tracking may not be available on time. The vendor has provided three possible delivery scenarios: - Best case: Module ready in 3 weeks (25% probability) - Most likely: Module ready in 5 weeks (50% probability) - Worst case: Module ready in 9 weeks (25% probability) The project's critical path includes this module integration, and any delay directly impacts the project completion date. Kayla needs to calculate the expected delivery time to update the project schedule and communicate realistic expectations to the executive steering committee, who have already expressed concern about delays affecting Q4 revenue targets. Based on the three-point estimate, what is the expected delivery time for the vendor module that Kayla should use for schedule planning?
