An agile team is incrementally delivering an infrastructure product over several iterations. Midway through the third iteration, the company announces that the operating systems supported by the infrastructure will be terminated next quarter, affecting thousands of machines. What should the project manager do first?

The correct first step is to schedule a session with stakeholders to determine the scope and impact. This critical initial action ensures all relevant parties understand the magnitude of the change, its implications for the project and the organization, and allows for informed decision-making. Without this understanding, any subsequent actions risk being misdirected or insufficient. Adding backlog items or requesting resources prematurely might address symptoms without fully grasping the underlying problem or its broader effects. Prioritizing machine upgrades with IT before understanding the full scope could lead to wasted effort if the strategic direction changes after stakeholder consultation.
