'''General Responsibility Assignment Software Patterns''' (or '''Principles'''), abbreviated '''GRASP''', is a set of "nineeight fundamental principles in [[object-oriented design|object design]] and responsibility assignment"<ref name="Larman2001"/>{{rp|6}} first published by [[Craig Larman]] in his 1997{{cn|date=February 2021}} book ''Applying UML and Patterns''.

The different patterns and principles used in GRASP are controller, creator, indirection, information expert, low [[coupling (computer science)|coupling]], high [[cohesion (computer science)|cohesion]], [[Polymorphism (object-oriented programming)|polymorphism]], protected variations, and pure fabrication.<ref name="Umair2018"/> All these patterns solve some [[software]] problems common to many [[software development]] projects. These techniques have not been invented to create new ways of working, but to better document and standardize old, tried-and-tested [[Computer programming|programming]] principles in object-oriented design.
