What is Code Quality?
Code Quality measures how well source code adheres to standards of readability, maintainability, performance, and security. High-quality code is easier to understand, extend, test, and troubleshoot.
How Does Code Quality Work?
It is assessed using a combination of manual code reviews, automated code analysis tools, testing frameworks, and adherence to best practices like clean code principles and design patterns.
What Are the Benefits of Code Quality?
- Reduces technical debt.
- Makes onboarding new developers faster.
- Improves system reliability and performance.
- Facilitates easier updates and feature additions.
How Can Code Quality Reduce Mean Time to Resolution?
Well-structured and documented code makes diagnosing, reproducing, and fixing bugs significantly faster, directly shortening time to resolution.
What are the Challenges of Code Quality?
- Achieving consensus on what “good” code looks like across teams.
- Time investment required for code reviews and refactoring.
- Balancing speed and code quality under business pressures.
