There are three main principles that will help to optimize your DevOps initiative.  You may have heard them referred to as The Three Ways . All three of the principles will have a role to play but for the purpose of Time vs. Cost, I would like to focus on the first way which is “The Flow of Work from Left to Right”.  When considering this flow of work think of the value stream from left to right as being from the time the request is made until the time that value is realized. Using LEAN methods and applying techniques like the Theory of Constraints we can increase velocity to apply just the right cadence to meet the evolving business demand.  These practices along with our DevOps integration, Continuous Delivery Pipelines and automation will radically increase the time to value for products and services.  Time is a key metric.  DevOps organizations use “time” as the primary measurement tool.   Why time is a better metric than cost: Ti...

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”. The Third ...

I recently published a blog that explained the Theory of Constraints.  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. The First Way  Workflow!  The first way is all about workflow or the flow of work from left to right. Generally referring to that flow of work between the business and the customer.  Work that is flowing from development to test and then test to operation teams is really only work in process.  Work in process really does not equate to anything until value is realized on the other side.  We must identify and remove or free up our constraints. For example, reducing the cycle from time of code commit to the time we are in production will reduce the release cadence. Ensuring the workflow from left to right can radically increase workflow throughout the delivery cycle....
