Traditionally, IT service components such as hardware, network, databases, applications and business services have been managed independently. These IT silos have inherent limitations for everyone in the business. For example, have your end users ever complained that the website is unavailable, yet the hardware, application and network teams report that the system is working fine? Has a critical server ever gone down, but the business impact is unknown to anyone in your organization except a few experts working on the issue? Has a network issue disabled a business application, but the help desk was unable to correlate the network problem with end users calling for assistance?
