Our approach: Internal Labor Market methodology


Mercer’s proprietary Internal Labor Market (ILM) Analysis® provides a fact-based approach for making many essential decisions about human capital. At a basic level, it raises fundamental questions about a firm’s workforce, such as who gets hired, who performs well, who advances, and who stays. At a more advanced level, ILM Analysis provides critical insights into an organization’s talent practices and focuses on the causal links between HR policies/programs and employee behaviors over time.

Our Workforce Strategy & Analytics (WSA) team was first established in 1994 as an R&D unit, focused on developing methods to measure the workforce and business impact of people practices.


In 2011, Mercer established the Workforce Sciences Institute, an offshoot of the original WSA team. The Institute’s primary objectives are to focus research efforts on the continued advancement and application of the new science of human capital management, from developing advanced analytic methods and constructs to measuring the economic impact of workforce management practices. WSA and the Workforce Sciences Institute operate as a cohesive unit, collaborating on client engagements and original research.
