GRASP-based reasoning helps designers and developers assign responsibilities in object-oriented designs, improving cohesion and reducing coupling.
Identify a sample class design and apply the nine GRASP patterns to assign responsibilities more effectively.

To reduce coupling, apply GRASP principles like Low Coupling and Indirection to assign responsibilities in object-oriented design, ensuring classes interact through stable interfaces and mediators to minimize direct dependencies.
The nine GRASP patterns for software design are Information Expert, Creator, Controller, Low Coupling, High Cohesion, Polymorphism, Pure Fabrication, Indirection, and Protected Variations, guiding responsibility assignment in OO systems.
Using GRASP patterns in a Java or C# code review involves mapping design decisions to principles like Controller and High Cohesion, documenting the rationale for responsibility placement to ensure safe, maintainable OO architecture.
Use the Pure Fabrication pattern instead of Information Expert when assigning a responsibility to the Information Expert would break High Cohesion or Low Coupling, justifying a fabricated class to preserve design balance.
GRASP guidance works effectively for teaching object-oriented design to software teams, providing canonical references and practical examples that help developers systematically assign responsibilities and document architectural reasoning.
