Responsibilities

Objects that act as servers manage a certain amount of responsibility

Responsibility
- Of an object, as reflected by the interface it provides to other objects
- Of an operation
  - Precondition for activation - proposition about prerequisites for calling
  - Postcondition - proposition about result or effects
- Well-defined responsibilities provide for coherent objects

You should care about the responsibilities of both objects and operations

The distribution of responsibilities will become a major theme later in the course
