According to the PMBOK® Guide, specifically regarding the Monitor and Control Project Work and Determine Budget processes, a project manager ' s authority is limited by the approved cost baseline and management reserves.
Exceeding the Budget: When a project experiences a cost increase (such as a 10% currency exchange fluctuation) and there is no contingency reserve left to cover it, the project manager has exceeded their spending authority.
Role of the Project Sponsor: The sponsor is the individual or group that provides the financial resources for the project. They are ultimately responsible for the project ' s business case and success. Because this issue impacts the project ' s financial viability and requires additional funding beyond the baseline, the project manager must escalate the situation to the Project Sponsor.
Risk vs. Issue: While exchange rate fluctuation is a known risk in international procurement, once it has occurred and there is no budget to address it, it becomes an Issue. The sponsor must decide whether to provide additional funds (from management reserves), reduce the project scope, or accept a lower quality of furniture to stay within the original budget.
Management Reserves: These are amounts of the project budget withheld for management control purposes (the " unknown-unknowns " ). Accessing these funds typically requires formal approval from the sponsor or a steering committee.
Analysis of other options:
Option A: The PMO provides support, governance, and templates. While they may offer advice on how to handle the documentation, they generally do not provide the additional funding needed to solve a project ' s budget deficit.
Option B: Escalating directly to the CFO skips the project ' s established governance structure. The project manager should follow the chain of command, which starts with the project sponsor.
Option C: The procurement team handles the contract and vendor relationship. While they can confirm the price increase and the exchange rate logic, they do not have the authority to grant additional budget to the project.
Per PMI standards, any significant variance that threatens the project ' s baseline and cannot be resolved using the project manager ' s allotted contingency must be escalated to the Project Sponsor for a strategic decision on how to proceed.
