Abstract
The development of a graduation research application aimed at social implementation leads to the practice of engineering design. In this paper, This paper reports on the contents of engineering design practice using the example of the development of a graduation research application in which I was involved as a supervisor and supporter. In this case, a difficulty arose in that the concept could not be finalized before development. This is thought to be due to circumstances within the graduation research. As countermeasures to this, The study proposes as a reference to explain the following: start development from the parts where the concept has been finalized, separate the code by parts and functions, and rewrite the code from scratch if the concept changes significantly.
