The DevOps Handbook Quotes

“The more assumptions we can invalidate, the faster we can find and fix problems, increases our resilience, agility, and ability to learn and innovate.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“New local knowledge is exploited globally throughout the organization.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“Complex work is managed so that problems in design and operations are revealed.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“doing the same thing twice will not predictably or necessarily lead to the same result. It is this characteristic that makes static checklists and best practices, while valuable, insufficient to prevent catastrophes from occurring. See”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“In technology, our work happens almost entirely within complex systems with a high risk of catastrophic consequences. As”

“We cannot achieve deployments on demand if every code deployment requires two weeks to set up our test environments and data sets, and another four weeks to manually execute all our regression tests. The countermeasure is to automate our tests so we can execute deployments safely and to parallelize them so the test rate can keep up with our code development rate.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“We cannot achieve deployments on demand if each of our production code deployments take weeks or months to perform (i.e., each deployment requires 1,300 manual, error-prone steps involving up to three hundred engineers). The countermeasure is to automate our deployments as much as possible, with the goal of being completely automated so they can be done self-service by any developer.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“We cannot achieve deployments on-demand if we always have to wait weeks or months for production or test environments. The countermeasure is to create environments that are on demand and completely self-serviced, so that they are always available when we need them.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“Even under the best circumstances, some knowledge is inevitably lost with each handoff. With”

“Small batch sizes result in less WIP, faster lead times, faster detection of errors, and less rework.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“Studies have shown that the time to complete even simple tasks, such as sorting geometric shapes, significantly degrades when multitasking. Of”

“interrupting technology workers is easy, because the consequences are invisible to almost everyone, even though the negative impact to productivity may be far greater than in manufacturing.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“Work is not done when Development completes the implementation of a feature—rather, it is only done when our application is running successfully in production, delivering value to the customer.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“work can bounce between teams endlessly due to incomplete information, or work can be passed onto downstream work centers with problems that remain completely invisible until we are late delivering what we promised to the customer or our application fails in the production environment.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“We increase flow by making work visible, by reducing batch sizes and intervals of work, and by building quality in, preventing defects from being passed to downstream work centers. By”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“we also design our system of work so that we can multiply the effects of new knowledge, transforming local discoveries into global improvements. Regardless of where someone performs work, they do so with the cumulative and collective experience of everyone in the organization.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“By seeing problems as they occur and swarming them until effective countermeasures are in place, we continually shorten and amplify our feedback loops, a core tenet of virtually all modern process improvement methodologies. This maximizes the opportunities for our organization to learn and improve.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“the %C/A can be obtained by asking downstream customers what percentage of the time they receive work that is ‘usable as is,’ meaning that they can do their work without having to correct the information that was provided, add missing information that should have been supplied, or clarify information that should have and could have been clearer.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“In the DevOps ideal, developers receive fast, constant feedback on their work, which enables them to quickly and independently implement, integrate, and validate their code, and have the code deployed into the production environment (either”

“for those organizations that provided a stock ticker symbol, we found that high performers had 50% higher market capitalization growth over three years. They also had higher employee job satisfaction, lower rates of employee burnout, and their employees were 2.2 times more likely to recommend their organization to friends as a great place to work.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“high performers were twice as likely to exceed profitability, market share, and productivity goals. And,”

“when something does go wrong, we conduct blameless post-mortems, not to punish anyone, but to better understand what caused the accident and how to prevent it. This”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“Even high-profile product and feature releases become routine by using dark launch techniques. Long before the launch date, we put all the required code for the feature into production, invisible to everyone except internal employees and small cohorts of real users, allowing us to test and evolve the feature until it achieves the desired business goal.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“If adopting DevOps could enable us, through better management and increased operational excellence, to halve that waste and redeploy that human potential into something that’s five times the value (a modest proposal), we could create $2.6 trillion of value per year.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“In addition to the human suffering that comes with the current way of working, the opportunity cost of the value that we could be creating is staggering—the authors believe that we are missing out on approximately $2.6 trillion of value creation per year, which is, at the time of this writing, equivalent to the annual economic output of France, the sixth-largest economy in the world.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“When people are trapped in this downward spiral for years, especially those who are downstream of Development, they often feel stuck in a system that pre-ordains failure and leaves them powerless to change the outcomes. This powerlessness is often followed by burnout, with the associated feelings of fatigue, cynicism, and even hopelessness and despair.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“It is virtually impossible to make any business decision that doesn’t result in at least one IT change.”
― Gene Kim, The DevOps Handbook: How to Create World-Class Agility, Reliability, and Security in Technology Organizations

“we are no longer able to respond quickly to our changing competitive landscape, nor are we able to provide stable, reliable service to our customers. As”
