PMP Practice: Assess Project Needs, Complexity, and Magnitude

Saoirse Henare-Kelly is leading a project for Chukwuemeka Obiora Industries to replace a legacy railway signaling system across 340 kilometers of track in three European countries. The project involves integrating hardware manufactured by a vendor with a 14-month lead time, coordinating with national railway authorities that require sequential approvals, and adhering to strict safety regulations that mandate detailed documentation before any installation begins. The contract includes fixed milestones tied to regulatory approvals, and penalties for delays exceed $2 million per month. During project initiation, the engineering lead suggests using an adaptive approach with two-week iterations to 'stay flexible and respond to discoveries during installation.' The sponsor is concerned this recommendation doesn't align with the project's constraints. What approach should Sasha recommend?
