Defining an Interaction Model: The Cornerstone of Application Design

Or, on the value of working with models. Of any kind.

“An interaction model is a design model that binds an application together in a way that supports the conceptual models of its target users. It is the glue that holds an application together. It defines how all of the objects and actions that are part of an application interrelate, in ways that mirror and support real-life user interactions. It ensures that users always stay oriented and understand how to move from place to place to find information or perform tasks. It provides a common vision for an application. It enables designers, developers, and stakeholders to understand and explain how users move from objects to actions within a system. It is like a cypher or secret decoder ring: Once you understand the interaction model, once you see the pattern, everything makes sense. Defining the right interaction model is a foundational requirement for any digital system and contributes to a cohesive, overall UX architecture.”
