The software development industry is increasingly realizing that success depends on a project’s long-term viability. To help with that effort, the Software Improvement Group (SIG) has identified ten guidelines for delivering code that’s easy to maintain and adapt over time. While a full examination of these guidelines is available in Building Maintainable Software (O’Reilly), this report focuses on their application in the real world. Author and agile consultant Abraham Marin-Perez briefly explores each guideline and uses a running example to demonstrate how they can work together in a production environment. You’ll also get case studies of ten European organizations companies that have significantly benefitted from these guidelines.
