# Introduction e classify the degree of reliability in systems into five discrete levels as shown below in the table:

Table 1: Discrete levels of classification of SRE maturity levels [1,3] Level Type
I Chaotic II Repeatable III Defined IV Managed V Optimizing
Also in lieu of various tenets of Site Reliability Engineering we include the following: Author: e-mail: anand.sunder@capgemini.com

Based on the interaction between people, processes, and technology and the five discrete levels of maturity we come here with a map of their interactions: Technology bridges the gap between people and processes, so across the discrete levels of maturity, i.e, Levels I -V the above diagram approximates the interactions in most of the cases occurring in real life scenarios.

We have also come up with an approximate flow map of the tenets across 5 discrete levels as shown below:

# W

A mature incident management (2) leads to better elimination of unnecessary toil (5).

An evolved exception handling (3) will lead to an evolved emergency response (4).

Ultimately Levels I-V of maturity will be mapped to various tenets as shown above, with highest level of maturity at chaos engineering (6).


# II.


# Conclusion

The abovementioned framework, can lead to some really insightful systemic understanding for improving reliability of services. Further insights and improved level of understanding can be extracted by applying this across multiple scenarios.
