The project manager should evaluate the consequences and meet with the client to explain the possible scenarios. This is because the project manager needs to balance the competing demands of scope, time, cost, quality, and stakeholder satisfaction. The project manager should not hire the resource without the client's approval, as this would violate the terms of the contract and the trust relationship. The project manager should not ask the client for a meeting and explain that the task will not be performed, as this would compromise the project objectives and quality standards. The project manager should not try to accomplish the task internally by leveling resources from other projects, as this would create risks and dependencies for both projects and potentially affect their performance. The project manager should evaluate the consequences of not hiring the external resource, such as the impact on the project schedule, quality, scope, and risks. The project manager should also identify alternative solutions, such as negotiating with the client, finding another resource, or modifying the project plan. The project manager should then meet with the client and explain the possible scenarios, highlighting the benefits and drawbacks of each option. The project manager should seek the client's input and feedback and try to reach a mutually agreeable solution that satisfies the project requirements and the client's expectations.
