Study Notes

Package Cohesion Principles

There are two principles of package cohesion: the Common Closure Principle (CCP) and the Common Reuse Principle (CRP).

Common Closure Principle

The Common Closure Principle aims to group classes that are likely to change together in the same package.
It focuses on minimizing the work to rebuild, test, and deploy a release.

Common Reuse Principle

The Common Reuse Principle is focused on grouping classes that are used together in the same package.
