What does maintenance involve in information systems?

Maintenance in information systems primarily involves making changes to a system after it has been implemented. This includes activities such as fixing bugs, updating software to improve performance, making enhancements based on user feedback, and adapting the system to changes in the business environment or technology landscape. Effective maintenance ensures the system continues to meet user needs and operates efficiently over time.

The focus on maintenance is crucial because systems are rarely static; they require ongoing support and adjustments to keep up with evolving requirements and to rectify any unforeseen issues that may arise after deployment. By continually maintaining a system, organizations can maximize their investments and ensure functionality aligns with current operational demands.

The other options, while related to various aspects of information systems, do not directly pertain to maintenance. Creating new systems, conducting user training, and evaluating requirements are all critical processes in the system development life cycle but occur at different stages than maintenance.
