Information technology (IT) centralization is the consolidation of an organization's technology resources.
Centralization initiatives are often initiated when it becomes apparent that allowing individual departments or branch offices to provision their own IT systems and services is not helping the organization meet its goals and objectives. When done correctly, IT centralization can not only simplify administrative tasks, it can improve security, make data management easier and save the company money.
Bring your own device (BYOD) and IT consumerization are additional factors driving enterprises to pursue IT centralization. Despite its advantages, however, IT centralization has its downside because it can detract from an organization's ability to be agile and quickly respond to changing business needs. It can also affect an organization's culture, perhaps unintentionally creating a working environment that accepts bureaucracy and stifles innovation.
