4. Create A Service Catalog

A service catalog is one of the most critical pieces of the services equation to put into place, Alley said, calling it the "interface for your business." More specifically, the service catalog outlines the services and the technology, processes and business strategies they align with. What exactly that looks like will be different for every business, he said, but can be determined by customer needs and how the IT and business services can be aligned to meet those needs.

"The service catalog to me ... it's where your IT services align with your business services," Alley said. "That’s why it's critical."
