Companies today are facing a big talent-management challenge. They simply do not have the capabilities they need in-house to transform their offerings, processes, and infrastructures—and they’re increasingly unable to persuade highly skilled professionals to come on board full-time, despite making attractive offers. In many fields—particularly technology, data sciences, and machine learning—the people with the most sought-after skills are freelancers. Integrating and managing a new “blended workforce” will be one of the main managerial challenges in the years ahead. Force-fitting the model used for temporary staff onto highly skilled freelancers won’t work, however. Firms must fully integrate these professionals into a highly cohesive internal team.This article looks at successful efforts to manage the blended workforce at companies such as Microsoft, M&C Saatchi, and Mars and lays out some of the most helpful lessons they have learned.
