Which environment is most likely to have frequent updates and changes?

The development environment is most likely to have frequent updates and changes because it is where new software applications and features are created and modified. Developers continuously write and test code to introduce new functionalities, fix bugs, and improve performance. This iterative process often involves numerous revisions as developers experiment and refine their work.

In contrast, the testing environment is typically used for validating the stability and functionality of software once it has been developed, which means it may not see as many changes as the development environment. The staging environment serves as a near-final step where the application is tested in an environment that closely resembles production, but it is not the primary place for frequent changes. The production environment, where the application is live and serving end-users, is usually more stable and is only updated after careful planning and testing to avoid disrupting service.
