Which phase in the System Development Life Cycle follows Implementation?

The phase that follows Implementation in the System Development Life Cycle is Operation/Maintenance. This phase is critical as it involves the ongoing functions required to keep the system operational after it has been deployed. During Operation/Maintenance, users interact with the system, and any necessary updates, bug fixes, and enhancements are addressed.

This phase ensures that the software continues to meet users' needs and adapt to changing requirements. It often includes user support, performance monitoring, and troubleshooting issues that arise during the system's life span.

In contrast, the other options represent different phases or aspects of the system lifecycle. Initiation refers to the initial stage where project goals and feasibility are defined, while Development/Acquisition involves the actual building or procurement of the system. Disposal pertains to the final phase, which deals with the retirement of the system once it becomes obsolete or is no longer useful. Thus, Operation/Maintenance is the logical continuation after Implementation, providing the necessary support and upgrades to sustain system functionality.
