Invention activities The invention activities, together with the capability map allows us to create a high level design of the system that we are envisioning. These should include a healthy mix of low fidelity paper prototypes (initial user interface model) that we can test with real-world users prior to embarking on the next phases of the process. We may also envision the required architecture at this time which will guide various aspects down the line.
The subject of Agile Modelling techniques is beyond the scope of this write-up. Once we have our high level requirements, a model depicting the intended use for the system is understood, an initial domain model which identifies fundamental business entity types and the relationship between them, and an initial user interface model which explores UI and usability issues.
