the project manager should communicate the situation to the appropriate stakeholders who are responsible for managing the supplier relationship and contract. The purchasing department can then take the necessary actions to mitigate the risk of supplier failure or default, such as negotiating new terms, finding alternative suppliers, or terminating the contract. The project manager should not add the situation to the risk register (A) or use the issue log (D) without informing the purchasing department first, as this would not address the root cause of the problem or prevent potential impacts on the project. The project manager should not identify competitors (B) without consulting the purchasing department, as this could violate the existing contract or procurement policies. References:
