The technical process that involves the actual implementation of a system is represented by the concept of implementation itself. This process focuses on taking the design specifications and translating them into a functioning system. It encompasses the activities necessary for developers and engineers to construct and integrate the various components of the system, making it operational according to the established requirements and design.
Implementation includes coding, assembling hardware components, and integrating different system parts into a whole, aligning them with the planned system architecture. This is a critical phase in systems engineering where the theoretical designs and models are realized in practical, usable forms. Successful implementation ensures that the system can eventually move into subsequent phases such as verification, operations, and transition, where it will be tested, used in real-world scenarios, or delivered to stakeholders.
In contrast, transition refers to moving a system from development to operational use, while operation deals with how the system functions in real environments. Verification focuses on ensuring that the system meets the specified requirements before it can be operational. Therefore, implementation is distinct in its role of being the actual execution phase where the system is built, making it the correct choice.
