SOLID Principles of Object-Oriented and Agile Design

Topic: Business
Robert Martin

Robert C. “Uncle Bob” Martin is a software craftsman, and one of the leading names in contemporary software development. His books and videos are immensely popular.

In this unique live training session, Uncle Bob will use his signature presentation style to explain the benefits of the SOLID approach to application development. Crafted and defined through decades of first-hand design experience, SOLID has five principles that, when followed, make software designs easier to understand, more flexible, and less problematic to maintain.

What you'll learn-and how you can apply it

  • SOLID principles of software design
  • Clean Clode basics
  • Ensure that dependencies are well managed so that the code remains flexible, robust, and reusable
  • Understand costs and trade-offs associated with object-oriented design and get a leg up in ensuring that your code base is much cleaner
  • Professional practices

This training course is for you because...

  • You are an application developer, programmer, software engineer, or systems analyst who wants to know what object-oriented design is all about.
  • You take pride in you development efforts.
  • You want to understand the benefits of object-oriented design, the most popular paradigm in contemporary application development.


  • Software development experience
  • Familiarity of common software design

Recommended Preparation:

Clean Architecture (book) - Part III Design Principles

Clean Code Video Series (video)

Clean Coder Video Series (Expanded Edition)

Clean Code (book)
