Silos are a natural phenomenon in the world of IT. The structure of hierarchies in IT creates control structures which promote silos, according to article author George Spafford. He goes on, however, to explain how ITIL—if implemented correctly—can reverse the tendency of IT to silo groups.
The first step Spafford lists is to make sure that groups understand they are working together to create value—it’s a perception shift above all else. Making sure that IT understand it is there to enable the business to succeed is all important if ITIL is going to succeed in breaking down the silos that have been created.
From there, Spafford suggests formalizing and promoting processes and data structures, designing and implementing processes with clear integration, and recognizing human factors. Once all of these items are addressed, there is a very high likelihood that IT will be able to break away from thinking in silo terms and instead think in organizational terms.
