内部工具通常会贯穿于多个生产系统，但一些与研发相关的功能除外，例如，针对开发
系统执行的额外复杂度以及用于构建和测试的代码合并。内部工具同生产服务系统有着
不一样的视角：比起业务系统，内部系统的单功能的重要程度显著提高。任何依赖系统
的故障都可能放缓开发人员的速度和增加团队的挫败感，并最终影响向客户交付软件的
速度。换句话说，如果你的软件供应链的第一部分出现问题，这个部分便会成为余下依
赖这一部分的其他部分的瓶颈。
“速度慢”是分布式系统中最难调试的问题。“不稳定”是内部工具团队经常听到的抱
怨。这两者共同催生了“如何在高复杂性系统中通过交互排查问题”的挑战。例如，当
基础设施或者测试不稳定时，开发人员编写代码的能力就会下降，他们对工具就会产生
不信任，从而导致沮丧。这种复杂性促使
