While implementing a communications system the client says they may close the project. The project manager schedules an urgent meeting to influence the client to continue. Which two tools or techniques can the project manager use? (Choose two.)

The project manager needs to present a compelling case to the client. Alternatives analysis allows the project manager to explore various options for the project's future, including potential modifications or different approaches, demonstrating flexibility and problem-solving. Cost-benefit analysis provides a clear financial justification for continuing the project by comparing the monetary and non-monetary benefits against the costs of completion, highlighting the value proposition. Voting, multi-criteria decision making, and autocratic decision making are primarily internal team decision-making tools and are not suitable for influencing an external client in this scenario. The client is the decision-maker, so the project manager's role is to provide data and options, not to facilitate a group decision or make an autocratic one.
