Explanation
= In a functional organization, the project manager has limited authority and control over the resources and processes that are outside their functional area. The purchasing department is a separate functional unit that may have its own policies, procedures, and priorities that are different from the project's needs. Therefore, the project manager should meet with the purchasing manager to find the source of the delays and agree on a purchasing schedule that aligns with the project schedule. This can help to resolve the issue, improve the communication, and foster a collaborative relationship between the project and the purchasing department.
The other options are not appropriate actions for the project manager to take. Option A is not proactive and does not address the root cause of the problem. Option B is not feasible and may violate the contract terms and the organizational policies. Option D is not realistic and may affect the project scope, quality, and stakeholder satisfaction.
