Measuring and managing code quality is essential for mobile apps as it ensures consistency, reliability, and maintainability of the codebase, ultimately impacting the app's safety, security, and delivery speed. Maintainingable code is simple, clean, and easy to read, while reliability measures the likelihood that a system will run without failure. Testability assesses how well the code supports testing efforts, and portability measures how usable the same code is in different environments. Mobile teams should consider these four aspects when measuring and managing code quality to ensure high-quality code delivery. By implementing tools like Bitrise's step library and Fastlane integration, mobile teams can streamline their build processes and improve code quality. The Mobile DevOps Assessment Survey (MODAS) provides insights into a team's mobile development processes, helping them identify areas for improvement and support enhanced performance.
