Software Craftsmanship

Overview

Software craftsmanship is a movement that emphasizes the coding skills of developers themselves. It extends agile development by focusing not just on working software, but on well-crafted software. The Software Craftsmanship Manifesto (2009) declares:

As aspiring Software Craftsmen we are raising the bar of professional software development by practicing it and helping others learn the craft. Through this work we have come to value:

• Not only working software, but also well-crafted software
• Not only responding to change, but also steadily adding value
• Not only individuals and interactions, but also a community of professionals
• Not only customer collaboration, but also productive partnerships

The Boy Scout Rule

"Leave the code better than you found it." — Robert C. Martin

Every time you touch code, improve it. Fix a name, extract a method, add a missing test, remove dead code. The cumulative effect of small, continuous improvements is a codebase that gets healthier over time rather than decaying.
