Final answer:
Assumed requirements are expectations that are not formally documented but are believed by team members to be part of a project's scope, impacting the design process.
Step-by-step explanation:
The best description of Assumed requirements is: Assumed requirements are those that people expect without having explicitly expressed them. These requirements are taken for granted and are often considered common sense or standard practice within certain contexts. Unlike explicitly stated requirements, which are clearly defined and communicated, assumed requirements are not formally documented, but they are expectations that team members believe to be included in a project's scope. This can lead to misunderstandings if not identified and discussed early in the design process.
Assumed requirements play a significant role during the design process, including the Define Requirements and Constraints step. Identifying and documenting these requirements is crucial because they can impact the evaluation of solutions and how the detailed design is developed. Clear communication about assumed requirements ensures that all stakeholders have a shared understanding of the project's expectations, which is essential for the successful implementation of a design.
