Which phase in the SDLC involves the physical deployment of the system?

The phase in the Software Development Life Cycle (SDLC) that involves the physical deployment of the system is the Implementation phase. During this phase, the developed system is put into operation for its intended users. This involves activities such as installing the software, configuring it to run in the production environment, and making sure that all components are functioning as expected. Additionally, this phase often includes user training and support to facilitate a smooth transition to the new system.

In contrast, the Development/Acquisition phase focuses on the creation or procurement of the software, where coding and initial testing take place. The Operation/Maintenance phase is concerned with the ongoing functionality and support of the system after it has been deployed, while the Disposal phase involves the decommissioning of the system and archiving or deleting data once it is no longer required. Therefore, the correct phase related to the physical deployment of the system is indeed the Implementation phase.
