Which term best describes the complexity facet when selecting an architect?

The term that best describes the complexity facet when selecting an architect is related to the intricate details and specialized knowledge required for a project. Technical requirements encompass the specific functionalities, codes, standards, and sophisticated systems that the architect must understand and be able to implement effectively. This facet is crucial since complex projects often have unique challenges, such as advanced technologies or innovative design elements, which necessitate an architect with the expertise to navigate these demands.

In contrast, considerations like the size of the project, project duration, and launch date, while important, do not inherently address the intricacies involved in the architectural process itself. The size might impact the resources required, project duration pertains to timelines, and launch date relates to scheduling, but none of these aspects delve into the technical specifications or complexities that can arise during the design and construction phases. Thus, technical requirements stand out as the primary indicator of complexity when it comes to selecting the right architect for the job.
