Overview of this book

Product development and release faces overlapping challenges due to the combined pressure of delivering high-quality products in shorter time-to-market cycles, along with maintaining proper operation and ensuring security in a complex high-tech environment. This calls for new ways of overcoming these challenges from design to development, to release, and beyond. SAFe® for DevOps Practitioners helps you use a DevOps approach with the Scaled Agile Framework and details how value streams help you resolve these challenges using examples and use cases. The book begins by explaining how the CALMR approach makes DevOps effective in resolving product development roadblocks. Next, you’ll learn to apply value stream management to establish a value stream that enables product development flow, measure its effectiveness through appropriate feedback loops, and find ways of improving it. Finally, you’ll get to grips with implementing a continuous delivery pipeline that optimizes the value stream through four phases during release on demand. This book complements the latest SAFe DevOps courses, and you’ll find it useful while studying for the SAFe DevOps Practitioner (SDP) certification. By the end of this DevOps book, you’ll have gained a clear understanding of how to achieve continuous execution and release on demand using DevOps and SAFe.

Monitoring queues

To enable Lean flow, you need to closely examine queueing theory, the mathematical field behind the behavior of queues and waiting in line (think Starbucks or the checkout area of your local supermarket!). A number of mathematical formulas will be useful in helping us make sure we understand what we have to do to ensure Lean flow. These are:

  • Little’s Law
  • Kingman’s Formula

Let’s see how we can use these elements of queueing theory to enable Lean flow.

Where are our queues?

A key difference between product development queues and product manufacturing queues is that the artifacts of product development (particularly software development) are not physical and it is difficult to grasp the progress until completion, whereas in manufacturing, you can visually ascertain the completeness of a product while on the factory floor. This invisibility factor makes it easy to ignore these queues, often at your own peril.
