The Convention over Configuration (CoC) pattern or design standard details that the design of code should follow particular conventions instead of requiring configuration. This can be applied in many places. Certain frameworks have the ability to be configured for their use in your code base which is where this standard emanated from. But, configuration can apply to many more things and at many more levels. Documentation, for example, is a form of configuration. It configures the reader. In the case of source code, if the source code requires the developer to read and understand documentation about the source code, the developer is required to absorb that configuration before the source code can be absorbed most efficiently.
Convention over Configuration has far reaching effects in the navigability of a particular code base. To a certain extent, the convention ends up being configuration as the developer must essentially be configured to use the convention...
