• Each object is a component that has responsibility in a community
• The activities(responsibilities) of a system are distributed among objects in the system
• Responsibilities in an object should be closely related

Dependency

[jimin-kiim]

Coupling and Cohesion

Coupling

• dependency among modules
  • the degree to which the ability to fulfill a certain responsibility depends upon the actions of another component
• 🎯 minimize

Cohesion

• the degree to which the elements of a module belong together.
  • the degree ti which the tasks assigned to a component seem to form a meaningful unit.
  • a measure how strongly-related and focused the various responsibilities of a software module are.
• 🎯 maximize
