====== General Responsibility Assignment Software Patterns (GRASP) ======

Craig Larman describes how to assign responsibilities to classes using the following principles and patterns:

  * [[principles:Controller]]
  * [[principles:Creator]]
  * [[principles:High Cohesion]]
  * [[patterns:Indirection]]
  * [[principles:Information Expert]]
  * [[principles:Low Coupling]]
  * [[patterns:Abstract Coupling|Polymorphism]]
  * [[patterns:Protected Variations]]
  * [[pattern:Pure Fabrication]]

He calls GRASP "patterns of general principles in assigning responsibilities"((Craig Larman: //[[resources:Applying UML and Patterns|Applying UML and Patterns – An Introduction to Object-Oriented Analysis and Design and Iterative Development]]// p. 219)). Some of these are really patterns but others are principles.
