Which two waterfall approach phases are involved?

The design phase is indeed part of the waterfall approach, but testing is a separate phase that occurs after implementation. Testing focuses on verifying that the software meets the specified requirements, rather than defining what those requirements should be. Therefore, this choice does not accurately reflect the initial phases involved in determining program capabilities.

Implementation refers to the actual development of the software after the design has been completed, while testing is performed afterward to ensure that the software functions correctly. These phases are focused on execution and validation rather than defining the operations that the software will support.

While design is a critical phase, implementation follows after the design has been established. The implementation phase is concerned with building the software according to the design specifications rather than determining what capabilities the software will have, which is the focus of the analysis phase.
