Google 评分卡

Google评分卡的来自Google的SRE。为了保证稳定可靠的服务，Google组建了一支专业的团队来负责运行后端服务，参与的工程师有一个共同的名字：Site Reliability Engineer。

对此，资深Google SRE Chris Jones等人联合撰写了《Google SRE: How Google runs production systems》，首次向外界解密了谷歌的生产环境，中文名字叫《SRE：Google运维解密》。

正是在该书中提到了上面所说的“Google评分卡”。下面来看看这11个等级到底是如何划分的：

评分卡

0：you are unfamiliar with the subject area.

0：不熟悉的领域。也就是说对相关的领域几乎一无所知。

1：you can read/understand the most fundamental aspects of the subject area.

1：可以读懂或理解相关领域的大多数基础知识。

2：ability to implement small changes,understand basic principles and able to figure out additional details with minimal help.

2：能够实现一些小的改动，理解基本原理，能够在简单的帮助下找出更多的细节。

3：basic proficiency in a subject area without relying on help.

3：基本精通相关技术领域，完全不需要别人的帮助。

4：you are comfortable with the subject area and all routine work on it.

4：对相关技术领域非常熟悉和舒适，可以应对和完成所有的日常工作。

For software areas - ability to develop medium programs using all basic language features w/o book, awareness of more esoteric features (with book).

对于软件领域，有能力开发中等规模的程序，能够熟练和掌握并使用所有的语言特性，而不需要翻书，并且能够找到所有的冷知识。

For systems areas - understanding of many fundamentals of networking and systems administration, ability to run a small network of systems including recovery, debugging and nontrivial troubleshooting that relies on the knowledge of internals.

对于系统领域，了解很多网络和系统管理的基础知识，能够运行一个小型的系统网络，包括恢复、调试和依赖于内部知识的重要故障排除。

5：an even lower degree of reliance on reference materials. Deeper skills in a field or specific technology in the subject area.

5：对参考资料的依赖程度更低。在某一领域或某一特定技术领域有较深的技能。

6：ability to develop large programs and systems from scratch. Understanding of low level details and internals. Ability to design/deploy most large, distributed systems from scratch.

6：能够从零开发大型程序和系统。掌握底层细节和内在原理。能够设计和部署大多数大型分布式系统。

7：you understand and make use of most lesser known language features, technologies, and associated internals. Ability to automate significant amounts of systems administration.

7：理解并利用高级语言特性、技术和相关的内在原理，可以从根本上实现大量系统管理和运维工作的自动化。

8：deep understanding of corner cases, esoteric features, protocols and systems including “theory of operation”. Demonstrated ability to design, deploy and own very critical or large infrastructure, build accompanying automation.

8：对于一些边角和晦涩的技术、协议和系统工作原理有深入的理解和经验。能够设计、部署并负责非常关键、规模很大的基础设施，并能够构建相应的自动化设施。

9：could have written the book about the subject area but didn’t; works with standards committees on defining new standards and methodologies.

9：能够在该技术领域出一本经典的书。并和标准委员会的人一起制定相关的技术标准和方法。

10：wrote the book on the subject area (there actually has to be a book). Recognized industry expert in the field, might have invented it.

10：在该领域写过一本书，被业内尊为专家，并是该技术的发明人。
