What is an instrumental model used for?

An instrumental model is primarily used to take measurements for analysis. This type of model is designed to represent the performance or functionality of a system in a way that allows for empirical data collection and evaluation. By measuring various parameters, designers can analyze how different factors affect the intended outcomes, thereby refining their designs based on solid data rather than assumptions.

In contrast, gaining user feedback through a realistic representation focuses more on the visual and experiential aspects, while testing a concept with user interactions emphasizes usability and user experience trials. Creating a visual concept of the final product is about communicating ideas and aesthetics rather than the analytical or empirical measurements that an instrumental model provides. Thus, the focus of an instrumental model on data measurement makes it distinct in its purpose and utilization within the design process.
