  3. Release/Reuse Equivalency Principle (REP) The granule of reuse is the

    granule of release. Only components that are released through a tracking system can effectively be reused. This granule is the package. — Robert C. Martin
  4. Release macht Code zum Produkt

  5. Zeitliche Entkopplung

  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
  15. None
  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
  17. None
  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
