Maxine loves coding and she’s awesome at it. But she knows that there’s something even more important than code: the systems that enable developers to be productive, so that they can write high-quality code quickly and safely, freeing themselves from all the things that prevent them from solving important business problems.

Everyone around here thinks features are important, because they can see them in their app, on the web page, or in the API. But no one seems to realize how important the build process is. Developers cannot be productive without a great build, integration, and test process. (Location 666)

developers need a system where they can get fast and continual feedback on the quality of their work. If you don’t find problems quickly, you end up finding them months later. By then, the problem is lost in all the other changes that every other developer made, so the link between cause and effect disappears without a trace. That’s no way to run any project.” (Location 771)
She had also forgotten that when you throw the Operations teams into the mix, the number of teams involved more than doubles, because getting all those applications running in production requires the server administration teams, virtualization teams, cloud teams, storage teams, networking teams (Location 1174)

Curious, she asks one of the them why he doesn’t seem very worried. He replies with a puzzled look, “I’m a developer—I work on features. I give them to QA and Ops to test and deploy. Then I work on the features for the next release. That keeps me plenty busy.” (Location 1231)

Once we get continuous builds going, we enable automated testing. We get automated testing, we can make changes quicker, with more confidence, and without having to depend on hundreds of hours of manual testing. And that, I believe, is the critical first step for how we can deliver better value, safer, faster, and happier. (Location 1789)
“Without continuous builds, we are like a car manufacturer without an assembly line, where anyone can do whatever they want, independent of the plant goals,” he continues. “We need to discover problems only when we are in the build or testing process, not during deployment or production.

‘technical debt is what you feel the next time you want to make a change.’ There are many things that people call technical debt, but it usually refers to things we need to clean up, or where we need to create or restore simplicity, so that that we can quickly, confidently, and safely make changes to the system. (Location 1934)
table turns their attention to him. “I’ve already told you about the First Ideal of Locality and Simplicity. We need to design things so that we have locality in our systems and the organizations that build them. And we need simplicity in everything we do. The last place we want complexity is internally, whether it’s in our code, in our organization, or in our processes. (Location 1972)
“The Second Ideal is Focus, Flow, and Joy. It’s all about how our daily work feels. (Location 1977)
The Third Ideal is Improvement of Daily Work. Reflect upon what the Toyota Andon cord teaches us about how we must elevate improvement of daily work over daily work itself. (Location 1986)
The Fourth Ideal is Psychological Safety, where we make it safe to talk about problems, because solving problems requires prevention, which requires honesty, and honesty requires the absence of fear. In manufacturing, psychological safety is just as important as physical safety. (Location 1987)
Fifth Ideal is Customer Focus, where we ruthlessly question whether something actually matters to our customers, as in, are they willing to pay us for it or is it only of value to our functional silo?” (Location 1989)

The joy that Maxine felt all day while working on the problem disappears. After all, fixing the code especially for features is just a fraction of the entire job. It’s not done until that customer can use what they’ve written. And even then, it’s probably still a work in progress, because we can always learn more about how to help that customer best achieve their goals. (Location 2176)
Technical debt is inherently neither good nor bad—it happens because in our daily work, we are always making trade-off decisions,” he says. “To make the date, sometimes we take shortcuts, or skip writing our automated tests, or hard-code something for a very specific case, knowing that it won’t work in the long-term. Sometimes we tolerate daily workarounds, like manually creating an environment or manually performing a deployment. We make a grave mistake when we don’t realize how much this impacts our future productivity.” (Location 2339)

“Business people can see features or apps, so getting funding for those is easy,” he continues. “But they don’t see the vast architectures underneath that support them, connecting systems, teams, and data to each other. And underneath that is something extraordinarily important: the systems that developers use in their daily work to be productive. (Location 2367)

“It’s funny: the tech giants assign their very best engineers to that bottom layer, so that every developer can benefit. But at Parts Unlimited, the very best engineers work on features at that top layer, with no one besides interns on the bottom working on Dev productivity. (Location 2370)

If someone gave us the authority, and we were given infinite resources for one month, what would we do?” Maxine smiles as she hears the suggestions fly fast and furious. They start making a list: Every developer uses a common build environment. Every developer is supported by a continuous build and integration system. Everyone can run their code in production-like environments. Automated test suites are built to replace manual testing, liberating QA people to do higher value work. Architecture is decoupled to liberate feature teams, so developers can deliver value independently. All the data that teams need is put in easily consumed APIs … (Location 2388)
“When something goes wrong, we ask ‘what caused the problem,’ not ‘who.’ We commit to doing what it takes to make tomorrow better than today. As Sensei John Allspaw says, every incident is a learning opportunity, an unplanned investment that was made without our consent. (Location 2435)
This is the opposite of the Second Ideal, she thinks. We’re just a stupid feature factory, pushing out widgets that customers may or may not care about. Work is not fun and full of joy, like I know it should be. There is no flow of features, there is no feedback, and there certainly isn’t any learning, (Location 2573)

We don’t even need guards anymore. We love being prisoners so much, we just think the bars are there to keep us safe. (Location 2937)
Ops, it’s worse, because we have so many areas of specialization. Complex work like deployments hit every one of those areas. We have servers, databases, networks, firewalls … heck, in the last decade, we’ve created even more silos, like storage, VLANs, automation teams, virtualization, hyperconverged infrastructure, and who knows how many more.

Prevention requires honesty, and honesty requires the absence of fear. Just like Norm Kerth says in the Agile Prime Directive, ‘Regardless of what we discover, we understand and truly believe that everyone did the best job they could, given what they knew at the time, their skills and abilities, the resources available, and the situation at hand.’ (Location 3715)

This service calls out to a bunch of external APIs from the shipping providers, and some of those are failing. Brent suspects that they are being rate-limited by one of them, because they’d never had Parts Unlimited servers send so many queries like this before. Maxine can’t believe that a service that seems so trivial is jeopardizing the entire launch. She smiles and makes a note of this, because she knows that this will likely be the new normal. But for something this mission-critical, there’s no way we should depend on external services, she thinks. We need to gracefully handle the case when they’re down or when they cut us off.

“Horizon 1 thrives on process and consistency, on rules and compliance, and on bureaucracies, which create extraordinary resilience.

“A hundred years ago, most large factories had a CPO—a chief power officer—who ran the electricity generation processes. It was one of the most important roles in manufacturing, because no electricity, no production. It was a Core process,” he says. “But that role has disappeared entirely. Electricity has become infrastructure that you buy from a utility company. It is interchangeable, and you choose suppliers primarily on price. There is rarely a competitive advantage to generating your own power. It is now merely Context, no longer Core. You don’t want to be the organization that has a large staff providing internal power generation. (Location 5134)

Teaching Thursdays.” Maxine’s heart leaps at the mention of this. This was something she had lobbied for, and now she’s getting it. Not just for the technology organization, but for everyone in the company. “Every week we will create time for everyone in the company to learn. For two hours, everyone is expected to teach something or learn something. (Location 5608)
They used a technique called Wardley Maps to better localize what parts of various value chains were commodities and should be outsourced, which should be purchased, and which should be kept in-house because they created durable, competitive advantage.
