In order to measure the ROI of talent mobility programs, you need to collect and analyze data from various sources and methods, such as surveys for gathering feedback from employees, managers, customers, or stakeholders; interviews for gaining more insights and stories from participants and sponsors; assessments for evaluating skills, knowledge, or behaviors of employees before and after their mobility assignments; and reports for tracking and comparing quantitative data and metrics of your programs. Surveys can help you ask questions about satisfaction, expectations, challenges, benefits, or suggestions for improvement. Interviews can help you learn about experiences, learnings, achievements, or recommendations for future programs. Assessments can help you use tools such as tests, simulations, or portfolios to measure learning outcomes and performance improvement. Reports can help you use tools like dashboards, scorecards, or charts to visualize and communicate your results and trends.
