HR wasn't involved in sourcing strategy. Either I contacted HR to open a req for a full-time employee, or I contacted Infosys. For body shops there was a specific system that sent it to multiple firms, but I was usually already talking to my account managers. When doing budgets we'd submit headcount asks by type and there were some soft ratios we were expected to stay within but this was mostly the division exec and their finance partner related to keeping our ratios aligned with our charge-back rates. I never saw a number that had anything to do with diversity across contractors.
