Which SDLC phase involves evaluating system performance and determining maintenance needs?

• A. Maintenance
• B. Planning
• C. Design
• D. Analysis

Answer: (A)

Maintenance focuses on keeping the system working well after it goes live. It involves monitoring how the system performs in real use—checking response times, resource usage, reliability, and user feedback—and then deciding what maintenance is needed. This can include bug fixes, performance tuning, applying updates, and planning future improvements to ensure the system continues to meet needs over time. Planning, analysis, and design are about defining, understanding, and building the system before it’s deployed, not ongoing upkeep.
