Maximize Abstraction
Initially hide the distinction between data and behavior.
Think of objects responsibilities for "knowing", "doing",
and "deciding"
Distribute Behavior
Promote a delegated control architecture
Make objects smart- have them behave intelligently, not
just hold bundles of data
Preserve Flexibility
Design objects so interior details can be readily changed
an application = a set of interacting objects
an object = an implementation of one or more roles
a role = a set of related responsibilities
a responsibility = an obligation to perform a task or know
information
a collaboration = an interaction of objects or roles (or
both)
a contract = an agreement outlining the terms of a
collaboration
