A strategy driven by business requirements to provide, and in many
cases guarantee, levels of service from IT (Information Technology)
to end users. The needs of the end users are the primary driver for
the development of the IT infrastructure. The benefits of defining
this strategy are higher return on investment in IT expenditures and
also the proper setting of expectations for all organizations involved.

Documents defining various service levels IT is expected to deliver to
the end user. These documents focus on individual applications and
the service levels required by the application users. SLAs can also be
used for budgeting, planning, and control purposes.
