Three key elements of building quality software efficiently are automation, standardized environments, and individual ownership. Automation eliminates tedious headaches by automating repetitive processes such as environment configuration, testing, and collaboration, freeing up developers to focus on high-value tasks like coding. Standardization ensures code integrity by providing consistent development environments, optimizing collaboration, and enabling seamless code reviews. Individual ownership empowers developers with control over their environment, allowing them to install personalized tools and frameworks without disrupting team standards, facilitating learning and innovation while maintaining consistency. By combining automation, standardization, and individual ownership, developers can form the "holy triangle" of efficient software development, resulting in huge time savings, improved code quality, and a competitive edge in delivering high-quality software efficiently.
