A project manager has been assigned to a project that is consolidating regional operations into a global operation. The project sponsor explains that some efficiencies

could be obtained from this unification. However, the sponsor is not sure if this effort will have a return on investment $($ROI$)$ and would like the project manager's

opinion.

What should the project manager do$?$

Request the project sponsor to include a commitment from the stakeholders to reduce costs within the project scope.

Explain that the project manager is limited to demonstrating earned value $($EV$)$ from the project execution perspective.

Suggest conducting a detailed cost$-$benefit analysis for financial feasibility before the start of the project.

Recommend conducting an initial high$-$level feasibility assessment to estimate the cost and benefits.
