I just completed a minimum viable product (MVP) version of my Unity game as part of my university project. I am unsure whether if I should also make a section with the UML use case diagrams in the thesis at this stage. I am asking because unlike an industrial project where the use case should be in the business modelling, elaboration or, and especially when modelling the system requirement, to understand the design requirements of the system, here I am not in a mockup or requirement gathering stage, which is long past and completed during the project proposal stage. Here I have a working prototype that is in the stage of being an MVP. Would it be wise for me to add it at this stage for an academic paper?
