Which type of maintenance would include introducing new software to increase efficiency?

The focus of perfective maintenance is on improving a system's performance or enhancing its functionality. This type of maintenance involves making changes to software to introduce new features or improve existing ones, thereby increasing efficiency within the system. By incorporating new software or updates, organizations can ensure that their systems remain relevant and capable of meeting evolving business requirements. Perfective maintenance is crucial for adapting to user needs and technological advancements, helping to streamline processes and optimize operations.

Corrective maintenance addresses software bugs and issues that need immediate fixing, while adaptive maintenance involves modifying the system to work in a new environment or with new technologies. Preventive maintenance, on the other hand, aims at avoiding future problems by performing updates and changes that are not necessarily responsive to current issues but are proactive maintenance measures. Each of these types serves a distinct purpose, but perfective maintenance is specifically aimed at enhancing functionality and operational efficiency through the introduction of new software.
