A Week with Sandi Metz’s Practical Course

#RubyOnRails

At CleverLabs, we pride ourselves on our extensive experience and expertise in Ruby on Rails development. Our team, composed of seasoned developers, continuously seeks opportunities to refine our skills and stay at the forefront of industry practices. Recently, we had the privilege of participating in Sandi Metz’s "Practical Object-Oriented Design" course, a week-long deep dive into advanced OOP principles, drawing heavily from her acclaimed book, "99 Bottles of OOP."


A Course Beyond the Basics

Given our team's strong foundation in object-oriented design, we initially wondered how much new material this course could offer. However, we were quickly impressed by how it challenged our preconceptions and deepened our understanding of design principles. Sandi’s course didn’t just reiterate familiar concepts—it recontextualized them, offering a fresh perspective on how to apply these principles in more complex, real-world scenarios.




Refining Code with Purpose

One of the most significant benefits of the course was its focus on practical application. Through the lens of the "99 Bottles" problem, Sandi guided us through the intricacies of refactoring and design decisions that optimize code for flexibility and future growth. For our team, the value lay in the emphasis on intentionality in design—ensuring that every line of code serves a clear, justified purpose.


This approach was particularly beneficial for our senior developers, who are accustomed to making quick design decisions under tight deadlines. The course encouraged us to take a step back and consider the long-term implications of our choices, reinforcing the importance of creating code that not only meets current requirements but is also robust and adaptable to future changes.


Advanced Concepts Made Accessible

Despite the advanced nature of the course, Sandi Metz’s teaching style made complex concepts accessible and actionable. The interactive format, combined with her clear explanations and real-world examples, helped our team bridge the gap between theory and practice. Concepts like SRP (Single Responsibility Principle), DRY (Don’t Repeat Yourself), and managing dependencies were explored in greater depth, highlighting their relevance in large-scale applications.


Moreover, the course underscored the importance of maintaining a balance between pragmatism and perfectionism in coding. While it’s easy to get lost in the pursuit of an ideal design, Sandi emphasized the need to recognize when "good enough" is truly good enough, a lesson that resonated with our experienced team.




A Lasting Impact

The "Practical Object-Oriented Design" course was more than just a refresher for our team; it was a catalyst for growth. It provided us with new tools and perspectives to approach our projects, ensuring that we continue to deliver high-quality, maintainable code for our clients. The lessons learned have already started influencing our daily practices, from code reviews to new project designs.


In conclusion, the course reinforced our commitment to excellence in software development. It demonstrated that no matter how experienced you are, there’s always room for improvement and refinement. For our team at CleverLabs, Sandi Metz’s course was an invaluable experience, providing insights that will shape our work for years to come.
