Managed services enable you to set contractual terms for IT tasks that include service level agreements (SLAs). This means you don’t have to spend time recruiting, hiring, or training your own IT staff. This allows you to pay only for the coverage or services you need. It makes budgeting uncomplicated. Also, there is no need to call an outside vendor (who knows nothing about your system) to come in and learn on the fly just to make a change.
