Which set of metrics best describes how to assess ROI for global mobility programs?

• A. On-time project completion only.
• B. Headcount growth only.
• C. Employee engagement surveys only.
• D. Cost per assignment, productivity, retention, knowledge transfer, and business impact.

Answer: (D)

Assessing ROI for global mobility programs requires a balanced view of both costs and the value created across multiple dimensions. Measuring efficiency, effectiveness, and impact together gives a true picture of return rather than focusing on a single facet.

Cost per assignment helps quantify the financial side by showing how much each relocation or global assignment costs the organization. Productivity assesses how quickly and effectively assignees contribute to business goals once on the ground, which reflects the operational value of mobility. Retention matters because maintaining talent post-assignment reduces the cost of turnover and ensures the investment in relocation yields long-term benefits. Knowledge transfer tracks the spread of skills and expertise throughout the organization, increasing overall capability and reducing dependency on a single individual. Business impact ties mobility to strategic outcomes—like market entry, revenue growth, or cost savings—demonstrating the actual contribution to organizational objectives.

Other options focus narrowly on one aspect: on-time project completion emphasizes timing rather than value; headcount growth looks at quantity of hires without linking to mobility outcomes or ROI; employee engagement surveys capture attitudes but not the economic return or strategic results of mobility. The comprehensive set above integrates cost, performance, talent retention, capability building, and measurable business outcomes, giving a true measure of ROI for global mobility programs.
