object-oriented design
OOD

    (OOD) A design method in which a system is modelled
   as a collection of cooperating objects and individual objects
   are treated as instances of a class within a class hierarchy.
   Four stages can be identified: identify the classes and objects,
   identify their semantics, identify their relationships and
   specify class and object interfaces and implementation.
   Object-oriented design is one of the stages of object-oriented
   programming.

   Schlaer-Mellor is one approach to OOD.
