Which phase involves the coding and development of the actual system?

The Implementation Phase is the stage where the coding and development of the actual system occur. During this phase, developers take the specifications and designs created in the previous phases and translate them into executable code. This involves setting up the necessary coding architecture, developing algorithms, writing code, and integrating all the system components to build a functional software application.

In the context of software development, this phase follows the design phase, where the system's framework and components were planned and detailed. Once the design is established, the next logical step is the implementation of that design. This phase is crucial as it brings the project visually and operationally into existence, allowing stakeholders to begin interacting with the system.

The subsequent phases, such as testing and deployment, focus on validating the development and making the system available for use, but they do not involve the actual writing of the system's code, which is the hallmark of the implementation phase.
