Accelerate DevOps with GitHub

By: Michael Kaufmann

Overview of this book

This practical guide to DevOps uses GitHub as the DevOps platform and shows how you can leverage the power of GitHub for collaboration, lean management, and secure and fast software delivery. The chapters provide simple solutions to common problems, thereby helping teams that are already on their DevOps journey to further advance into DevOps and speed up their software delivery performance. From finding the right metrics to measure your success to learning from other teams’ success stories without merely copying what they’ve done, this book has it all in one place. As you advance, you’ll find out how you can leverage the power of GitHub to accelerate your value delivery – by making work visible with GitHub Projects, measuring the right metrics with GitHub Insights, using solid and proven engineering practices with GitHub Actions and Advanced Security, and moving to event-based and loosely coupled software architecture. By the end of this GitHub book, you'll have understood what factors influence software delivery performance and how you can measure your capabilities, thus realizing where you stand in your journey and how you can move forward.

High-performance companies

Organizations with a high engineering velocity outperform their competitors and disrupt markets. But what exactly are high-performance companies?

The Developer Velocity Index

In April 2020, McKinsey published their research about the Developer Velocity Index (DVI) (Srivastava S., Trehan K., Wagle D. & Wang J. (2020)). This is a study taken among 440 large organizations from 12 industries that considers 46 drivers across 13 capabilities. The drivers are not only engineering capabilities—they also contain working practices and organizational enablement such as the company culture. The study shows that the companies in the top quartile of the DVI outperform other companies in their market by four to five times, and not only on overall business performance. Companies in the top quartile score between 40 and 60% higher in the following areas:

  • Innovation
  • Customer satisfaction
  • Brand perception
  • Talent management

The study conducted interviews with more than 100 senior engineering leaders at 440 large organizations across 12 industries. The interview contained 46 drivers across 13 capabilities in 3 categories, outlined as follows:

  • Technology: Architecture; infrastructure and cloud adoption; testing; tools
  • Working practices: Engineering practices; security and compliance; open source adoption, agile team practices
  • Organizational enablement: Team characteristics; product management; organizational agility; culture; talent management

The DVI, therefore, goes way beyond pure developer velocity. It analyzes the engineering velocity and all the factors that influence it and relates them to business outcomes such as revenue, shareholder returns, operating margin, and nonfinancial performance indicators such as innovation, customer satisfaction, and brand perception.

The state of DevOps

The findings align with the results from the DevOps Research and Assessment (DORA) State of DevOps report (https://www.devops-research.com/research.html#reports) but take them one step further by adding the business outcomes. The DevOps Report 2019 states how elite performers compare against low performers (Forsgren N., Smith D., Humble J. & Frazelle J. (2019)), as outlined here:

  • Faster value delivery: They have a 106-times faster lead time (LT) from commit to deploy.
  • Advanced stability and quality: They recover 2,604 times faster from incidents and have a 7-times lower change failure rate (CFR).
  • Higher throughput: They do 208 times more frequent code deployments.

High-performance companies not only excel in throughput and stability but are also more innovative, have higher customer satisfaction, and greater business performance, (see Figure 1.3).

Focusing on the measures that highlight the capabilities that set apart high-performance companies from medium and low performers, you can make your transformation visible and provide management with metrics that hopefully matter more to them than lines of code or estimation-based velocity.
