Always written up as one of the selling points for outsourcing of IT.  But what are some examples?

Some which come to mind:

Providing an ITIL standard support desk – with established policies, procedures, logging, portal access, reporting.  An ITIL certified vendor brings this to the table and manages all support calls through a structured process.

Providing out of hours support – potentially this may not be affordable within the internal organisation – but the vendor, already providing 24*& support to toher clients, may be able to provide this at a very competitive price.

Purchasing/ renting equipment – may be able to leverage greater buying power of the vendor.
