- Make your products live longer! Refactoring means taking the opportunity to keep your product alive. Don't ditch it, stitch it! Don't end it, mend it! Refactoring is not a needless cost. It is anti-needless complexity that prevents change.
- Design should be simple so that it is easy to refactor. Product designers: Make your products easy to change. Write clean, understandable code. Consumers: Buy products that are continuously refactored, or else find out why the developers didn't do that. Be critical and inquisitive.
- Refactoring is not rewriting. Rewriting is throwing away the broken bit. This is NOT the kind of refactoring that we're talking about.
- What doesn't kill it makes it stronger. Every time we refactor code, we add to its potential, its history, its soul and its inherent beauty.
- Refactoring is a creative challenge. Refactoring is good for the imagination. Using new techniques, tools and materials ushers in possibility rather than dead ends.
- Refactoring survives fashion. Refactoring is not about styling or trends. There are no due-dates on continuously refactored code.
- To refactor is to discover. As you refactor objects, you'll learn amazing things about how they actually work. Or don't work.
- Refactor – even in bad times! If you think this manifesto is not relevant during recession, forget it. This isn't about effort, it's about mentality.
- Refactoring is about independence. Don't be a slave to legacy code – be its master. If it's broken, refactor it and make it better. And if you're a master, empower others.
- You can refactor anything, even total crap. But we'd recommend avoiding total crap. Refactoring stops code from becoming crap.
Stop Rewriting. Start Refactoring.
