What is the main purpose of establishing criteria in the design process?

The main purpose of establishing criteria in the design process is to ensure functionality and user satisfaction. Criteria serve as a set of standards or guidelines that help designers evaluate their work against specific goals and requirements. By defining what the design needs to achieve—such as performance, safety, usability, and aesthetic appeal—designers can create solutions that meet the needs and expectations of users. This focus on functionality and satisfaction also drives the iterative process of refining designs, ensuring they not only work effectively but also address user needs comprehensively.

For instance, if a designer is creating a new product, the established criteria might include durability, ease of use, and cost-effectiveness. These criteria guide the design choices and help assess whether the final outcome meets the necessary performance metrics before it is completed and presented to users.
