Except in sectors where high-volume recruitment is the norm, an organization faced with sudden, unexpected requirements for an unusually large number of new recruits often delegates the task to a specialist external recruiter. Sourcing executive-level and senior managementas well as the acquisition of scarce or ‘high-potential’ recruits has been a long-established market serviced by a wide range of ‘search and selection’ or ‘headhunting ’ consultancies, which typically form long-standing relationships with their client organizations. Finally, certain organizations with sophisticated HR practices have identified there is a strategic advantage in outsourcing complete responsibility for all workforce procurementto one or more third-party recruitment agencies or consultancies. In the most sophisticated of these arrangements the external recruitment services provider may not only physically locate, or ‘embed’, their resourcing team(s) in the client organization's offices, but work in tandem with the senior human resource management team in developing the longer-term HR resourcing strategy and plan.
