Staff augmentation is a flexible outsourcing strategy that allows companies to add skilled professionals to their existing teams on a temporary basis. It is often used to address skill gaps, handle peak workloads, or support specific projects. This approach enables businesses to scale their workforce quickly without the long-term commitment of hiring full-time employees. It provides access to specialized expertise and cost savings by avoiding traditional hiring expenses. While beneficial, it requires effective integration and management of external staff within internal teams.
