The main features of a software development workflow include planning, coding, testing, deployment, and monitoring. In the planning phase, teams define requirements and goals. Coding involves writing the actual source code based on the specifications. Testing is crucial for identifying bugs and ensuring the software functions as intended. Deployment is where the software is released to users, and monitoring tracks its performance and user feedback post-release. Effective workflows also incorporate version control and collaboration tools to streamline communication among team members and facilitate continuous improvement.
