What is the final phase of the systems development life cycle aimed at ensuring ongoing support?

The final phase of the systems development life cycle (SDLC) is focused on maintaining the system and evaluating its performance to ensure it continues to meet user needs and operational requirements. This phase is known as maintenance and evaluation.

During this phase, any issues that arise after implementation are resolved, updates are made to adapt to changing requirements, and regular evaluations are conducted to assess the system's effectiveness. This ongoing support is critical for sustaining system robustness and improving functionalities based on user feedback. Thus, by prioritizing maintenance and evaluation, organizations can prolong the life of their systems, enhance user satisfaction, and ensure that the technology remains relevant in meeting business goals.

The other phases, while essential to the overall development process, do not focus on the continuous support aspect that is necessary once a system is up and running.
