During the earliest parts of development, surveys were sent to qualified individuals to determine the needs of the consumers. All of this information was tabulated to create a Design Concern Table, which acted as the most basic blueprint that any design must follow. The Design Concern Table is broken up into six distinct categories.
As seen below, each assessed measure has its own subcategories, which are evaluated in two ways - Requirements and Goals. A Requirement is something that must be achieved in order to be considered as a design possibility. A Goal is something that while is not necessary to the integral part of the design, it is strongly desired; the more goals a design fulfills, the more likely the design is the best solution.
Below is the Design Concern Table used to preform evaluation on design possibilities.
