In software engineering and system engineering, a use case is a technique for capturing functional requirements of systems and systems-of-systems.This would be a fantastic method of ideation. Rather that using a use case to desribe how to achieve a goal or task, use it to describe how to a respresent a subject artistically or describe how to create a particular vision.
Each use case focuses on describing how to achieve a goal or task. For most software projects this means that multiple, perhaps dozens, of use cases are needed to embrace the scope of the new system.
Ain't half clever these software developers.
Incidentally, I discovered that Edinburgh University's Informatics department, have a person employed specifically to inform the staff about and create digital art. How good is that?
