There are five phases in the systems development life cycle (SDLC). Match the description of each phase to the correct phase.

1. The phase of the SDLC that involves a complete, detailed analysis of the systems needs of the end user as well as a proposed solution.
2. The phase of the SDLC that involves development, testing, and implementation of the new proposed system.
3. The phase of the SDLC that involves describing in detail the desired features of the system that were uncovered in the analysis phase.
4. The final phase of the SDLC that includes making changes, corrections, additions, and upgrades (generally smaller in scope) to ensure the system continues to meet the business requirements that have been set out for it.
5. The phase of the SDLC that summarizes the business needs with a high level view of the intended project.

A. Analysis phase
B. Design phase
C. Implementation phase
D. Maintenance phase
E. Planning phase
