What types of vendor bidding models do you use? In our 2011 Contingent Buyer Survey, we asked respondents to specify which vendor bidding model(s) they used. Eighty-four percent noted they use primaries (contingent workforce recruiting opportunities distributed to a select handful of primary staffing agencies, which may in turn subcontract some jobs), a large increase from 2007. Gaining less traction was the sole-source model (CW recruiting opportunities serviced via a single master vendor, which may subcontract some jobs).
