This document discusses the importance of technical practices in sustainable software development. It emphasizes that Agile leaders must demand technical excellence in the coming years to avoid failures. Various technical practices are presented that can help improve code quality, such as reducing variable scope, simplifying conditional logic, and following the "Boy Scout Rule" of leaving the code cleaner than how you found it. Pair programming, simple design, and software craftsmanship are also highlighted as pillars for sustainable development.
