The document outlines the typical design process model for interaction design which includes: 1) Defining goals, requirements, and scope in a mission statement and requirements document. 2) Conducting discovery research such as interviews, observations and context mapping to understand user needs. 3) Creating conceptual designs like personas, scenarios and flowcharts to address the identified needs. 4) Developing physical designs including prototypes, wireframes and style guides to realize the conceptual designs. 5) Testing designs through usability studies and iterating based on results.
