The phase of the Software Development Life Cycle (SDLC) that describes all functional features of the system independently of any computer platform is known as logical design. During this phase, the focus is on outlining what the system should do, identifying the functionalities and behaviors required, and establishing the system's specifications without getting tied to specific technologies or platforms. It is more about modeling the requirements and ensuring that the overall design meets the users' needs, serving as a blueprint for the subsequent phases of the development process.

In contrast, the implementation phase involves the actual coding and configuration of the system based on the specifications laid out in previous phases, which includes platform-specific considerations. The development phase often overlaps with implementation, as it entails creating the software itself, also considering technology choices. The testing phase is where the functionality is validated against the requirements, but by this point, the functionalities have already been defined and implementation has occurred. Therefore, logical design stands out as the appropriate phase focused on functional features free from platform constraints.
