14. Common Reuse Principle (CRP) The classes in a package are reused together. If you reuse one of the classes in a package, you reuse them all. — Robert C. Martin
16. Common Closure Principle (CCP) The classes in a package should be closed together against the same kinds of changes. A change that affects a package affects all classes in that package. — Robert C. Martin
18. Acyclic Dependencies Principle (ADP) The dependency structure between packages must be a directed acyclic graph (DAG). That is, there must be no cycles in the dependency structure. — Robert C. Martin
