Checkpoints:  Design Package

• The name of each package is unique and descriptive of the collective responsibilities of the model elements which it contains.
• 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.
