We recommend that enterprises follow an eight-step process to build a services catalog

The steps include:
Step 1: Understand Existing Services Assets
Step 2: Understand Cloud Services Assets
Step 3: Identify Required Types of Automation
Step 4: Define Use of Automation
Step 5: Establish Operations Planning
Step 6: Identify Candidate Services
Step 7: Deploy Initial Services Catalog
