More Is More Complex (MIMC): ECV demands adding a new class for a new varying concept.
Model Principle (MP): ECV sometimes results in classes which do not correspond top a real-world concept in the sense of MP. A “concept that varies” can also be a technical concept.
Complementary Principles
Dependency Inversion Principle (DIP): ECV may result in the creation of abstract classes (i.e. the concepts) and descendant concrete classes (i.e. the variations). DIP now tells that other classes should only depend on the abstractions.
