According to the PMBOK® Guide, specifically within the Monitor Risks and Manage Stakeholder Engagement processes, external dependencies—such as government or public authority approvals—represent a significant risk to project completion.
Issue Escalation: Since the project is in its final stages (three months left) and the authority is " stalling, " this is no longer just a risk; it is an issue. When a project manager encounters a roadblock that is outside their direct sphere of influence (external bureaucratic stalling), they must inform the major stakeholders and the project sponsor.
Corrective Actions and Legal Support: Construction projects are governed by contracts and local laws. Stalling by a public authority can have massive financial implications. Exploring corrective actions may include re-sequencing work to accommodate the delay, while legal assistance is often required to navigate regulatory hurdles, ensure compliance, or invoke specific clauses that protect the organization ' s interests against arbitrary delays.
Stakeholder Management: Reporting the issue ensures that those with the most influence (executives or sponsors) can use their political or professional capital to assist the project manager in resolving the bottleneck.
Analysis of other options:
Option A: While talking to a department head might seem proactive, a project manager often lacks the organizational standing to " demand " solutions from a public authority head. This approach ignores the formal governance and legal frameworks usually required in construction.
Option B: This is the most professional and standard-aligned response. It recognizes the limits of the PM ' s authority and utilizes the organization ' s broader power (stakeholders and legal) to address a critical external threat.
Option C: In most jurisdictions, public authority jurisdictions are non-negotiable. You cannot simply " request an alternative authority " to provide a legal approval if they do not have the legal mandate to do so.
Option D: Demanding an explanation in person is aggressive and often counterproductive. In project management, " demanding " is rarely an effective strategy for managing external stakeholders who hold the power of approval.
Per PMI standards, when an external dependency threatens the project ' s critical path and is outside the PM ' s control, the PM must report the issue to stakeholders and seek corrective and legal pathways to resolve the impasse.
