Speeding up the pace from a traditional service delivery life cycle requires automation tools, which present opportunities and challenges to the infrastructure and operations (I&O) organization. I&O pros are expected to participate across the modern service delivery life cycle, and as such need to master life-cycle automation tools and understand when to use them. This report highlights the most commonly used tools, some new and some repurposed, and describes how to link them to most effectively create flow across the entire service delivery life cycle. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
