 The map for the *Improve your Reliability* learning path is based on a model from the site reliability engineering world called the Dickerson Hierarchy of Reliability. Mikey Dickerson was an SRE who became the founding administrator of the United States Digital Services. He created this hierarchy while facing one of the largest reliability crises ever.

 The model is patterned after Abraham Maslow's *hierarchy of needs*, which addresses human motivation. As with Maslow's hierarchy, to progress up the hierarchy you need to make sure that each of the lower levels has been addressed first. The levels on which we focus in this learning path, from bottom to top, are:

 There are two more levels in the hierarchy that aren't addressed in the *Improve your Reliability* learning path: the development process and the work that goes into making a good user experience (UX). These two subjects aren't discussed in the *Improve your Reliability* learning path, but other good Learn modules on these subjects are available.
