Рефакторинг. Улучшение существующего кода

The book emphasizes improving existing code without changing its behavior. I'm curious how this concept has influenced real-world projects or team practices.

While the techniques seem invaluable, balancing refactoring with tight deadlines can be tough. What strategies have others used to make space for these practices?

His insights seem to have shaped modern coding standards. I'm interested in what motivated him to focus specifically on this aspect of software development.
