Which can help to reverse back to the previous baseline at any point of SDLC?

Version control systems (VCS) are essential tools that can help reverse to a previous baseline at any point in the Software Development Life Cycle (SDLC). By tracking changes and maintaining a history of modifications, developers can easily revert to earlier versions of code or documentation. Additionally, methodologies like agile and practices such as branching and merging facilitate managing different versions and features effectively. This flexibility ensures that teams can recover from errors or changes in project direction without losing significant progress.
