How ITIL 4 and SRE align with DevOps

In the early days of DevOps, there was a lot of debate about the ongoing relevancy of ITIL and IT service management (ITSM) in a faster-paced agile and DevOps world. Thankfully, that debate is coming to an end. ITSM processes are still essential, but, like all aspects of IT, they too must transform. Recent updates to ITIL  (ITIL 4), as well as increased interest in site reliability engineering (SRE), are providing new insights into how to manage services in a digital world. Here's a look at ITIL 4 and SRE and how each underpins the "Three Ways of DevOps," as defined in The Phoenix Project, by Gene Kim, Kevin Behr, and George Spafford.‎ What is ITIL 4?  ITIL 4 is the next evolution of the well-known service management framework from Axelos. It introduces a new Service Value System (SVS) that's supported by the guiding principles from the ITIL Practitioner Guidance publication. The framework eases into its alignment with DevOps and agile through a bi-mo

The Best of the Professor: The Third Way

The “Best of the Professor” blogs focus on one unique individual topic and will be followed by links to papers with more in depth information. DevOps initiatives are supported by three basic principles. In his book “ The Phoenix Project “, Gene Kim  leverages the Theory of Constraints and the knowledge learned in production environments to describe the underlying principles of the DevOps movement in three ways. These principals are referred to as The First Way, The Second Way and the Third Way.    In earlier papers from the “Best of the Professor” we discussed  the “First Way” and how this DevOps principle was all about the flow of work from Left to Right.  We then discussed the “Second Way which was all about the flow of work from right to left and how critical that is for measuring DevOps value.  In this iteration from “The Best of the Professor“, the focus will be on the last of these three DevOps Principles known as “The Third Way”.
