System Model vs Interaction Model: Where does the designer fit?

In the field of product design, it is important to understand the exact role of a Product Designer in relation to the system vs Interaction model. First of all, what is the system model? The system model refers to how something works. In contrast the interaction model refers to the how users use a product. A real-world example of these two models can be found in observing how users interact with a mobile application. When a user is ordering a ride via Uber, they do not understand the code or algorithms running in the back end in order to make their vehicle booking successful. The user does however understand how to the Uber app to order a ride and complete their goal. The role of the product designer is to fill in the gap between the system and interaction model. Product designers can see seen as a translator between both models. As a product designer you will become stronger by understanding the system model, this may involve learning some basic coding or at least practice coding a project from start to finish. By doing this you will have a better understanding for the entire pipeline and you will work more effectively with product development teams.

    This is really enlightening and an important aspect of product design to keep in mind! It’s also interesting how this might translate to other fields of design, like web design for example.
