When I started at Intelliware many years ago, it was common practice for new employees to be given one or more books to read. In my case, I received Extreme Programming Explained, by Kent Beck. It was 2005, and the way that Intelliware worked was almost verbatim by the book, “the book” being Extreme Programming Explained. The influence of extreme programming, its values and practices continues today at Intelliware. Every day, our project teams Refactor, Pair, write Automated Unit Tests, work on Short Releases, assume Collective Code Ownership, and Continuously Integrate. Over time, we’ve drifted away from handing out recommended reading on day one for new employees, but we still have a bookish culture.
Earlier this year, I was wondering what other books have influenced Intelliware, so I asked my colleagues to vote. I went into the exercise assuming “Extreme Programming Explained has got to be number one, but what are the next few on the list?” I put out a call for nominations, organized some interviews to talk about the books, and wrapped up with some voting. To my surprise, XP Explained was not voted number one, although it was in the top five. As Churchill said, “Democracy is the worst form of government, except for all the others.”
See the end of this post for a sorted list of all the nominated books. After the voting, Intelliware’s Top Three books were:
1. Clean Code, by Robert Martin
2. Refactoring, by Martin Fowler
3. Clean Architecture, by Robert Martin
Our top picks by Robert Martin and Martin Fowler are detail-oriented books that deal directly with the mechanics of software development. All three of these books use the “Boy Scout Rule” metaphor, encouraging software developers to leave the codebase cleaner than we found it, and give catalogues of methods to do that cleanup and many examples of how. Over the years, my colleagues and I have gathered in study groups and labs to discuss and learn from these books.
Our second choice, Refactoring by Martin Fowler, describes a core practice from Extreme Programming. Refactoring is defined as a change made to the internal structure of software (to make it easier to understand or cheaper to modify) without changing its observable behaviour. As my colleague, Diego Correa said when I was interviewing him, “If we don’t pay attention to what we are doing, just changing code, not trying to improve it…it will get more complex, more confusing, creating more bugs and increasing the cost to maintain this code.” Refactoring can make it easier to add a feature, or it can improve your understanding of the code. Most of Refactoring is a catalogue of techniques. Each entry describes the steps to execute a refactoring safely and efficiently, but also describes the motivations to choose that refactoring. The book is packed with examples.
Our first and third choices, both by Robert Martin, are Clean Code and Clean Architecture. Clean Code gives advice and direction at the most detailed levels of software development. It helps with naming things, choosing the right responsibilities for functions, concurrency, and unit testing. Focusing on the details and improving code differentiates clean code from bad code. This book attracts practitioners who want to get better at the craft of software. Clean Architecture moves from the low-level details up to the higher-level structure of software. Martin points out that design exists on a continuum from low to high level, so there is not a clear distinction between code design and architecture.
So, what’s next? I expect that we will revisit many of our top books over the next few years with study groups, talks, and labs. I am also looking forward to getting a list of our top blogs, videos, and other non-books. I will report back, but until then, keep reading and talking about software development.
