Which of the following is NOT considered an input of the Architectural Design Process?

The architectural design process relies on various inputs to inform and guide the development of a system's architecture. System requirements outline what the system must achieve and serve as a foundational input. Concept documents provide initial ideas and frameworks for potential solutions. An updated requirements traceability matrix is vital for tracking how requirements evolve and their relationships, ensuring that all requirements are addressed in the architectural designs.

However, the documentation of implemented solutions does not serve as an input into the architectural design process. Instead, this type of documentation typically arises after architectural design has been executed and the system has been developed. It reflects what has already been created rather than providing guidance or requirements for new design activities. Therefore, this option accurately represents something that is not considered an input of the architectural design process.
