Small and frequent commits are essential in Continuous Integration (CI) because they enable fast feedback, reduce integration issues, and support a more stable development process. By committing small chunks of code regularly, developers isolate changes, making it easier to identify, test, and fix bugs quickly. This approach minimizes the complexity of code merges and prevents large-scale integration conflicts that typically arise from infrequent, bulk updates. Frequent commits also allow CI systems to run automated builds and tests continuously, ensuring that new code does not break existing functionality. Moreover, small commits improve code review efficiency, enhance team collaboration, and create a more traceable and transparent development history. This disciplined practice aligns well with agile and DevOps methodologies, ultimately resulting in higher code quality, faster delivery, and lower development risk.
