The product backlog has been completed and prioritized.

According to the Project Management Professional (PMP) principles, a project manager’s role in an Agile environment includes facilitating the team’s progress towards project goals. This often involves removing obstacles or ‘blockers’ that are hindering the team’s progress. In this situation, the delay in signing the external vendor contract is an impediment that is affecting the project. Therefore, the project manager’s priority should be to assist with the removal of this impediment so that the project can continue. References: Project Management Professional (PMP) Certification Handbook, PMBOK Guide (6th Edition), Chapter 9: Project Resource Management, Section 9.6 Control Resources.
