In this course we will examine rules for validating architectures and review approaches to refactoring to help development teams ensure that their existing applications and architectures are sound.

By the end of this course, you will be able to:

• Validate an application’s architecture using the 3 validation rules.
• Use the Discovery tool to view and analyze an application's architecture.
• Refactor application architectures to improve flexibility and maintenance.
• Prioritize the changes that should be made during refactoring.
• Extract elements from a module without impacting consumers.
