Which aspect of software requirements management deals with maintaining software integrity during changes?

The aspect of software requirements management that deals with maintaining software integrity during changes is software configuration management. This practice encompasses ensuring that all the components of the software are kept consistent and functional, even as modifications and updates are made.

Software configuration management involves keeping track of all changes made to software items and their relationships, which helps in managing how changes affect overall system integrity. This includes version control, change control, and monitoring changes to maintain the integrity of the system throughout its lifecycle. It specifically focuses on preventing unintended errors or inconsistencies that could arise from changes, ensuring that each version of the software behaves as intended.

In contrast, while requirements analysis focuses on understanding and specifying what the software must do, requirements documentation serves to capture these requirements in a formal manner. Requirements gathering, on the other hand, involves collecting essential information from stakeholders. While these processes are crucial for defining and managing software requirements, they do not specifically address the ongoing management of integrity during changes.
