Version Control refers to the management of changes to documents, computer programs, large web sites, and other collections of information. It is about tracking and providing control over who made what change (and when), which allows for easy identification of what was changed, by whom, why, and when. This fits into the Application Lifecycle Management hierarchy as it plays a crucial role in managing changes throughout the entire lifecycle of software development, including integration, testing, tracking bugs, and managing different versions of the codebase. It is also closely related to Change Management as it enables organizations to effectively manage and control changes to ensure that they are implemented in a structured and predictable manner. Version Control provides an essential foundation for efficient collaboration, traceability, and accountability across teams and stakeholders, ultimately leading to improved software quality, reliability, and maintainability.
