A project manager created a contingency plan for a known risk. The risk occurred, but the client insists on using a new workaround that will cause delays and need extra budget. What should the project manager do?

The correct answer is to discuss the options with the client as part of the change control process. Even though a contingency plan exists, the client is requesting a different approach (a workaround) that impacts scope, schedule, and cost. This constitutes a change request, which must be formally processed through the integrated change control process. This ensures all stakeholders are aware of the implications and formally approve the new direction. Proceeding with the originally approved risk response plan would disregard the client's explicit request and could lead to dissatisfaction or further issues. Requesting management reserve might be a partial solution but doesn't address the client's desire for a specific workaround. Mitigating risks introduced by the workaround is a good step, but it should happen after the client's requested change is formally discussed and approved, not as the primary immediate action.
