Which of the following has PRIMARY responsibility to define the requirements for IT service levels for the enterprise?

Business managers are closest to the operational needs of the enterprise and understand the impact of IT service levels on their specific business processes, productivity, and profitability. They are therefore best positioned to articulate the necessary requirements for availability, performance, and other service attributes that IT must provide to adequately support their functions and achieve business objectives.

The help desk is an operational unit that delivers IT services and monitors performance, but it does not define the strategic service level *requirements*.

While the CIO is accountable for IT service delivery, they rely on business managers to provide the actual requirements that dictate those service levels.

A business continuity vendor provides specific services related to disaster recovery, but they do not define the overall IT service level requirements for the enterprise.
