虽然组织通常会以极其紧迫的态度处理面向客户的生产环境故障，但往往会忽视那些保障开发团队正常运转的基础设施。对于工程团队而言，开发流水线——包括构建系统、CI/CD 工具和质量保证（QA）环境——本身就是一套生产系统。当开发人员无法编译代码或测试人员无法访问 QA 服务器时，团队交付价值的能力便会停止。正如制造业优先保障流水线正常运行一样，软件组织也必须为内部工具故障采取同样的“全员响应”心态。为了保持生产力，团队必须拓宽对“生产故障”的定义，将其涵盖软件交付过程中的任何瓶颈，从问题追踪系统和集成开发环境（IDE），到构建仓库和测试套件。将内部流水线故障视为与面向客户的故障同等重要的紧急事项，对于持续的软件交付至关重要。简而言之：如果开发流水线瘫痪，团队就等于离线了——这必须被视为最高优先级的紧急情况来处理。

这篇 Hacker News 讨论批评了将“开发流水线”视为任务关键型“生产系统”的观点。虽然参与者承认 CI/CD 流水线的中断会阻碍软件交付，但许多人反对将其归类为正式的“生产故障”。批评者认为，这种术语混淆了开发工具与面向用户服务之间的区别。另一些人指出，将两者等同起来会造成优先级判定问题：将每一个内部技术障碍都视为高严重性事件，容易导致“寻呼疲劳”，使工程师被非关键性的警报淹没。讨论中一个反复出现的主题是，为“开发者体验”基础设施争取管理层支持的困难。由于预防性维护的价值通常是隐形的——不像数据泄露或面向客户的崩溃那样明显——高管们往往在灾难发生前不会优先考虑这些系统。归根结底，虽然参与者一致认为强大的开发工具对业务成功至关重要，但大多数人认为，将这些内部流程贴上“生产”的标签是一种策略性的夸大，忽视了随叫随到文化和资源分配中的实际情况。

Software developers learn early in their careers that nothing is more urgent than fixing a production outage. Drop everything! All hands on deck!

However, the same level of urgency is not often given to problems with our development tools, build systems, QA environments, and other parts of the software development pipeline. But for the development team, the development pipeline is a production system.

A software developer’s job is to deliver value for the company. Sometimes that means building new features, sometimes that means fixing critical bugs for the customers’ production systems. But none of this can happen when something is broken in the software development pipeline.

If the code can’t compile, the developers are unable to do their jobs, and the team isn’t producing software. For the development team, this is a production outage. Fixing this should be a top priority.

If the QA server is down, the testers are unable to do their jobs, and the team isn’t producing working software. For the QA team, this is a production outage. Fixing it should be a top priority.

A software assembly line, on fire — You will not be shocked to learn that I drew this myself.

In manufacturing, there are extensive processes and procedures on how to prevent and minimize downtime on the assembly line.^{And similar processes exist for IT service outages. But I’ve found that most of those focus on outages in the service provided to customers, not for the people responsible for building and supporting the services.}

I recommend thinking about all the components that take you from “customer wants something” to “that something is delivered to customers”:

Issue reporting and change request systems, like GitHub Issues, Jira, etc
Tools developers use to directly build software, like IDEs, build tools (Gradle, Maven, etc), package repositories (npm, Maven Central, internal repositories, etc), local databases, containers, etc
CI/CD tools (Jenkins, GitHub Actions, etc).
A failing test suite (surely you don’t deploy to production if the tests are failing?)
QA server outage (surely you don’t deploy to production if QA hasn’t tested it?)
Literally any step in your process that prevents you from making changes and deploying them to production

A team with a broken development pipeline can’t produce software, and must treat this as a production outage.
