Continuous integration (CI) is significant in software delivery as it promotes frequent code changes, leading to faster development cycles. By automatically integrating code updates into a shared repository, CI reduces integration issues and maintains software quality. Automated testing ensures early detection of bugs, which minimizes the risk of defects in the production environment. This approach encourages collaboration among developers and helps streamline workflows. As a result, CI contributes to quicker release times and enhanced responsiveness to user feedback, allowing businesses to adapt swiftly to market demands.
