“This is great stuff! Your descriptions are so vibrant and vivid that I’m rediscovering the truth buried in OO principles that are otherwise so internalized that I forget to explore them. Your thoughts on design and knowing the future are especially eloquent.”
—Ian McFarland, President, New Context, Inc.
“As a self-taught programmer, this was an extremely helpful dive into some OOP concepts that I could definitely stand to become better acquainted with! And, I’m not alone: there’s a sign posted at work that reads, ‘WWSMD? – What Would Sandi Metz Do?’”
—Jonathan Mukai, Pivotal in NYC
“Meticulously pragmatic and exquisitely articulate, Practical Object Oriented Design in Ruby makes otherwise elusive knowledge available to an audience which desperately needs it. The prescriptions are appropriate both as rules for novices and as guidelines for experienced professionals.”
—Katrina Owen, developer, Bengler
“I do believe this will be the most important Ruby book of 2012. Not only is the book 100% on-point, Sandi has an easy writing style with lots of great analogies that drive every point home.”
—Avdi Grimm, Author of Exceptional Ruby and Objects on Rails
“While Ruby is an object-oriented language, little time is spent in the documentation on what OO truly means or how it should direct the way we build programs. Here Metz brings it to the fore, covering most of the key principles of OO development and design in an engaging, easy-to-understand manner. This is a must for any respectable Ruby bookshelf.”
–Peter Cooper, editor, Ruby Weekly
“So good, I couldn’t put it down! This is a must-read for anyone wanting to do object-oriented programming in any language, not to mention it has completely changed the way I approach testing.”
–Charles Max Wood, video and audio show host, TeachMeToCode.com
“Distilling scary OO design practices with clear-cut examples and explanations makes this a book or novices and experts alike. It is well worth the study by anyone interested in OO design being done right and ‘light.’ I thoroughly enjoyed this book.”
–Manuel Pais, editor, InfoQ.com
“If you call yourself a Ruby programmer, you should read this book. It’s jam-packed with great nuggets of practical advice and coding techniques that you can start applying immediately in your projects.”
–Ylan Segal, San Diego Ruby User Group
“This is the best OO book I’ve ever read. It’s short, sweet, but potent. It slowly moves from simple techniques to more advanced, each example improving on the last. The ideas it presents are useful not just in Ruby but in static languages like C# too. Highly recommended!”
–Kevin Berridge, software engineering manager, Pointe Blank Solutions, and organizer, Burning River Developers Meetup
“The book is just perfect! The elegance of Ruby shines but it also works as an A to Z of object-oriented programming in general.”
–Emil Rondahl, C# & .NET consultant
“This is an exceptional Ruby book, in which Metz offers a practical look at writing maintainable, clean, idiomatic code in Ruby. Absolutely fantastic, recommended for my Ruby hacker friends.”
–Zachary “Zee” Spencer, freelancer & coach
“This is the best programming book I’ve read in ages. Sandi talks about basic principles, but these are things we’re probably still doing wrong and she shows us why and how. The book has the perfect mix of code, diagrams, and words. I can’t recommend it enough and if you’re serious about being a better programmer, you’ll read it and agree.
–Derick Hitchcock, senior developer, SciMed Solutions
“I predict this will become a classic. I have an uncomfortable familiarity with programming literature, and this book is on a completely different level. I am astonished when I find a book that offers new insights and ideas, and even more surprised when it can do so, not just once, but throughout the pages. This book is excellently written, well-organized, with lucid explanations of technical programming concepts.”
–Han S. Kang, software engineer and member of the LA Rubyists
“You should read this book if you write software for a living. The future developers who inherit your code will thank you.”
–Jose Fernandez, senior software engineer at New Relic
“Metz’s take on the subject is rooted strongly in theory, but the explanation always stays grounded in real world concerns, which helped me to internalize it. The book is clear and concise, yet achieves a tone that is more friendly than terse.”
–Alex Strasheim, network administrator, Ensemble Travel Group
“This is an amazing book about just how to do object-oriented thinking when you’re programming in Ruby. Although there are some chapters that are more Ruby-specific, this book could be a great resource for developers in any language. All in all, I can’t recommend this book enough.”
–James Hwang, thriceprime.com
“Whether you’re just getting started in your software development career, or you’ve been coding for years (like I have), it’s likely that you’ll learn a lot from Ms. Metz’s book. She does a fantastic job of explaining the whys of well-designed software along with the hows.”
–Gabe Hollombe, software craftsman, avantbard.com
“In short, this is in my top five programming books I’ve ever read. I believe that in twenty years this will be considered one of the definitive works on object-oriented programming. I plan to re-read it at least once a year to keep my skills from falling into atrophy. If you’re a relatively new, intermediate, or even somewhat advanced OO developer in any language, purchasing this book is the best way I know to level up your OO design skills.”
–Brandon Hays, freelance software developer

The book addresses OOP Anti-patterns and the Reader is taken through iterative steps in evolving the Example Applications throughout the chapters. In some ways, it can be likened to thinking in more of a 'Data-Modeling' Manner, though adapted for OOP instead of Relational Databases.
If you work in Software, you should read or re-read this book. The author also has a more recent book available through her web site, which is of similar quality though has more of a Programming or Puzzle-like Feel.
The term "design" in the title is not referring to making wild speculative guesses about the future and planning for any number of contingencies, it is about arranging the code so that it is understandable, and to minimize cost and pain.
There is a focus on designing the communication between objects as much as focusing on the structure of the objects themselves, which I found to be extremely interesting. This discussion helped clarify a lot of thoughts and ideas about abstractions and where responsibilities belong, as well as the directions of dependencies -- things that had been rattling around in my brain for a while but that I had trouble applying in the real world. Reading this let me put all these pieces together (and then some) into a coherent whole. Or at least a coherent seed of a whole.
The code examples are simple, but the author manages to wrangle some serious dramatic tension out of every line of code, and they illustrate the concepts covered well enough that I was able to make the leap to applying the concepts in much more complex code bases.
The chapter on testing was sublime. It took an immensely practical approach to which methods to test and which tests to write in order to avoid duplication and brittleness in both tests and designs.
I also appreciated that none of the discussions were about any sort of moral superiority. The discussions were about getting things done. The argument for arranging code nicely wasn't about aesthetics or professional duty, but rather about lowering cost and allowing you to make changes without causing expensive outages and making people frustrated.
Soap boxes? Sure. High horses? Nowhere in sight.
Note: I read a pre-release version of the book. I did not know the author at the time, but sent her quite a lot of feedback, which led to several conversations to clarify. When I waxed enthusiastic about the contents, she asked if she could forward this to the publisher, and a quote ended up in the paper copy.
The only real ding to the book is Chapter 8's references to Enumerable and Forwardable. Everything else in the book was either easy to read or well explained. These two characters seem to have slipped in without fanfare or explanation. I don't understand them and thus probably missed some of the book's goodness. Perhaps I'll get it later. I still rate this book a 5 star buy!
I'm only two chapters in and I definitely feel as if this book has already paid itself off.
The book starts off with plenty of insight on OOP and delivers direct and immediately actionable insight.
Thank you Sandi Metz for this amazing book!
