This study introduces you to design principles in Ruby. Design principles are rules-of-thumb that help you make decisions about how to structure your code and design your classes. Good design helps manage complexity, makes code resilient to changing requirements, and makes it less expensive to change.

• Ruby Object Model
• Ruby Object
• Ruby Object Practice

By the end of this, developers should be able to:

• Recall each principle in the abbreviation SOLID
• Recognize "code smells" that suggest refactorings toward SOLID design
• Refactor code using design heuristics
