Udemy – Mastering GRASP Principles in Object-Oriented Design

This course is a deep, practical, and brutally honest guide to GRASP – not a theoretical overview and not a slide driven abstraction. GRASP is one of the most misunderstood and misused foundations of object oriented design. Many developers hear the names of the principles, but almost nobody knows how to apply them correctly, how they conflict, and how real design decisions are actually made. This course fixes that.

• You will not just learn what each GRASP principle is.
• You will learn how to think like a designer.

What makes this course different:

• This is not a definitions course.
• This is a decision making course.

You will see:

• Why GRASP is more fundamental than SOLID
• Why many “best practices” directly violate GRASP
• Why blindly following principles creates worse designs
• How professional architects actually balance trade-offs

Every principle is explained through:

• Clear mental models
• Real domain driven examples
• Explicit anti-patterns
• Live refactoring and demos
• Architectural context, not isolated classes

What you will learn

You will master responsibility assignment, which is the core skill behind all good object oriented systems.

Specifically, you will learn how to:

• Identify the true Information Expert in a domain model instead of creating fake experts and data classes
• Decide when Low Coupling is more important than perfect responsibility placement
• Avoid God Controllers and correctly map system events to controllers
• Design classes with High Cohesion and detect cohesion violations early
• Replace conditionals with Polymorphism only when it actually improves the design
• Use Pure Fabrication without turning your system into a service soup
• Apply Indirection to reduce coupling without destroying clarity
• Protect unstable parts of the system using Protected Variations and abstractions

Each topic includes:

• Correct examples
• Incorrect examples
• Clear explanation of why one design fails and the other works
