Language pervades every aspect of organizational life. It touches everything. Yet remarkably, leaders of global organizations, whose employees speak a multitude of languages, often pay too little attention to it in their approach to talent management. As we have observed in countless organizations, unrestricted multilingualism creates inefficiency in even the most dedicated and talented workforces. It can lead to friction in cross-border interactions, lost sales, and a host of other serious problems that may jeopardize competitiveness (see also “Global Business Speaks English,” by Tsedal Neeley, HBR May 2012). Developing a comprehensive strategy for managing language can help transform that vulnerability into a source of competitive advantage.
