In a successful enterprise that is profitable in its marketplace and consistently growing in size, the non-IT workforce has grown by 50% in the last two years. The demand for IT staff in the marketplace is more than the supply, and the enterprise is losing staff to rival organizations.

The MOST critical activity for reducing the impact caused by IT staff turnover is to:

A. outsource the IT operation.
B. increase compensation for IT staff.
C. hire temporary staff.
D. document processes and procedures.
