During which phase of the systems development life cycle (SDLC) is a new system constructed?

The systems implementation phase is when the new system is actually constructed and made operational. This stage involves coding, testing, and deploying the software solution. It includes all activities that convert the approved design into a working system, such as building the software, configuring hardware, and performing user training to ensure that the end users are familiar with the new system.

This phase is critical because it is where the theoretical work and planning from previous phases are put into practice, and any identified requirements from the design phase are turned into tangible software and systems. Successfully completing this phase leads to the deployment and operational use of the system, fulfilling the objectives set out in earlier phases of the SDLC.
