Final answer:
The standards that describe how design success (or failure) will be measured are criteria. Criteria are measurable values used to compare different designs and determine which one better solves the design problem. Prototypes are tested to evaluate the design's performance and determine if it meets all constraints and criteria.
Step-by-step explanation:
The standards that describe how design success (or failure) will be measured are called criteria. Criteria are measurable values that can be used to compare different possible designs and determine which one better solves the design problem. They are used to evaluate the quality of a design and are essential in the design process.
Criterion is a measurable standard or attribute of a design, such as weight and size. Constraints, on the other hand, are limitations or conditions that must be satisfied by a design. Constraints describe the conditions that a design must meet, while criteria are used to compare designs and determine which one is better.
One way to measure design success is through the process of testing and evaluating prototypes. Prototypes are tested to see if they meet all constraints and perform acceptably according to the criteria. By testing prototypes, engineers can determine if a design is successful or if changes need to be made.
