  • The package description accurately reflects the collective responsibilities of the model elements which it contains.
  • The publicly visible classes of the package provide a single, logically consistent set of services.
  • The dependencies between the package and other packages are consistent with relationships between contained classes
  • The package contents represent a consistent set of highly cohesive model elements, loosely coupled to elements in other packages.
  • There are no opportunities to further sub-divide the package into sets of highly cohesive model elements by taking advantage of loose coupling within the package.
  • The total number of packages is proportional to the total number of model elements.
