Which of the following is a stated benefit of code quality?

• A. Faster hardware upgrades
• B. The benefits: Customer satisfaction, predictability, and integrity of development, scalability, higher velocity and performance, and ability to innovate
• C. Decreased need for testing
• D. Shorter planning cycles

Answer: (B)

Code quality brings measurable benefits across the product and the development process. When code is clean, maintainable, well-tested, and easy to modify, the software behaves more reliably, which drives customer satisfaction because users get a stable, predictable experience. It also improves predictability for the team: with clear design, fewer defects, and better test coverage, plans and deliveries become more reliable and less risky. The integrity of development increases as changes are safer, architecture stays coherent, and refactoring doesn’t introduce unexpected problems. Good code quality supports scalability because modular, well-structured code can grow without becoming brittle. It tends to raise velocity and performance because teams spend less time wrestling with defects and rework and can implement enhancements more quickly. Finally, with fewer firefights and less technical debt, teams have more bandwidth to innovate. By contrast, faster hardware upgrades, a decreased need for testing, or shorter planning cycles aren’t direct, stated outcomes of code quality.
