What systems analysis and design stage involves creating the new system from the design?

The stage that involves creating the new system from the design is implementation. During this phase, the actual construction of the system takes place, which includes coding, hardware setup, and integrating the different components according to the system design specifications.

Implementation is crucial because it transforms theoretical designs and plans into a functioning system that users can operate. This stage also encompasses any necessary data migration and setting up user interfaces and experiences described in the design phase.

While production may refer to the overall functionality and availability of the system to users, it typically implies the system is already operational rather than focusing on the creation aspect of the design. Therefore, implementation is the most accurate description of the process that involves bringing the design to life.
